French Space Command, news, discussions

@Amarante , do you have any information about France's hypersonic missile program (V-MAX)?
Not a lot. Quite frustrating… here are some elements: opex360, jan.02:

The ASN4G [for Air Sol Nucléaire 4e génération] is expected to replace the ASMP-A [Air-Sol Moyenne Portée - Amélioré] nuclear-capable cruise missile currently used by the Rafale B of the Strategic Air Forces [FAS] by 2035.

To this end, under the aegis of the Direction Générale de l'Armement [DGA], the Office National d'Etudes et de Recherches Aérospatiales [ONERA] and MBDA are working on the development of a mixed ramjet, i.e. an engine that can successively perform subsonic and supersonic combustion.

In July 2021, Olivier Dessornes, deputy director of ONERA's Multiphysics Department for Energy [DPME], told
Air&Cosmos that a test of a hypersonic vehicle propelled by a statomix engine would soon be conducted. The vehicle "will be accelerated to the desired altitude for a sounding rocket. The data will be collected before the vehicle melts and its remains are lost at sea," he explained.

Hence the questions expressed by MP François Cornut-Gentille in a question to the Ministry of Defence last September. Especially since the technology to be tested is very sensitive... The parliamentarian has just received the answers to these questions... with some additional details.

Indeed, in a reply published on 28 December in the
Journal Officiel, the Ministry of the Armed Forces revealed that the test in question was called "ASTREE". And that, initially, it should have been carried out in Russia. What the annexation of Crimea, in March 2014, finally prevented.

In detail, he explained, it was a "scientific experiment aimed at recalibrating simulation models for a super ramjet", carried out by ONERA and MBDA with a "research model whose definition is optimised for a reduced operating range, not representative of the expected operating range of an operational system".

He added: "Its manufacturing technology, which cannot be used for a functional device, aims to guarantee that measurements are obtained at the point of the targeted domain.

This test could have been carried out in France if the facilities likely to host it had not been dismantled nearly forty years ago.

"This experiment was relaunched with the United States a few years later, as the installation of such a model in its operating range requires a suitable launch system (launch site and acceleration boosters), which has not been the case in France since the 1980s," explains the Ministry of Defence.

On the other hand, the tests of the VMax hypersonic glider demonstrator, announced by the Minister for the Army, Florence Parly, in January 2019, will be able to be carried out in France, as the DGA has taken the necessary measures to this end.

"The missile testing department of the French Defence Procurement Agency [...] is conducting work in order to once again have this type of capability on French territory. A first capability should be available in 2022," the Ministry of Defence concluded.

(Unseenlabs press release, feb.18)

UNSEENLABS REVEALS SHIPS THAT VANISHED FROM CONVENTIONAL GEOLOCATION SYSTEMS​

Since early November, more and more vessels navigating in Chinese waters are disappearing from the tracking systems normally used in maritime transport, likely following the introduction of the new Chinese law on the protection of personal information, which came into effect last 1st November.

This law compels all handlers of Chinese data to get government’s approval before any transfer of data to foreign countries. Although the law does not specifically mention sea freight, maritime companies could be withholding information just to be “on the safe side” while waiting to know exactly what they are allowed to share. The enforcement of this law and the blockage of information are worsening the current shipping crisis and congestion of ports. From 21 to 28 of last November, Unseenlabs made several satellite acquisitions in East China sea to highlight the ships now missing from AIS screens.

Context
Since early November, a growing number of ships seem to vanish from conventional tracking systems as they approach Chinese coasts. According to VesselsValue, the number of ships broadcasting AIS signals from Chinese waters has dropped by 90% since the entry into force of the new law.

Normally vessels can be identified via their AIS transponders, which broadcast the ship’s geolocation as well as other information such as its MMSI number (a unique 9-digit number associated with each ship) type (carrier, tanker, fishing vessel), nationality, course, speed… The AIS identification system was made compulsory for most ships by the IMO (International Maritime Organization) to all signatory flag states of the SOLAS convention (Safety of Life at Sea) to facilitate traffic and avoid collisions. But since its implementation wider uses of the system have developed, and it has become an essential tool for port management, by providing information on berth availability and anchorage waiting times among other things.

While it has its flaws as a surveillance tool, the AIS system has become essential for the management and monitoring of sea freight flows worldwide.

Chinese authorities invoke national security and sovereignty issues for this measure,
saying that foreign intelligence agencies and companies use the AIS system to keep track of Chinese military vessels and gather sensitive economic intelligence, according to a Chinese state media report. Although nothing in the law refers to AIS data, maritime transporters are being cautious and withholding the data while waiting for more information.

As a result, most ships are not visible from traditional surveillance systems once they get close to Chinese shores. In this new context, the AIS system doesn’t provide an accurate picture of traffic at sea, as shown in Unseenlabs’ series of satellite acquisitions in that area (space-based radiofrequency signals detection): in the sample below, more than 60% of ships in the area have disappeared from AIS screens.


Blind zone: disruption of global maritime traffic
An important consequence of this new regulation is the disruption of sea traffic due to a lack of data on ships positions: six of the world’s ten busiest container ports are in China, it is therefore essential to have visibility on ships departures, arrivals, and general flow of activity around Chinese shores.

An exhaustive picture of traffic at sea with space-based RF signal interception.

Unseenlabs conducted an eight-day satellite acquisition campaign in East China Sea, revealing a consequent gap in AIS data: up to 80% of ships located with RF detection don’t broadcast an AIS signal(AIS beacons turned off or data transmission blocked by Chinese authorities).

Unseenlabs’ radiofrequency detection system allows for an exhaustive picture of marine traffic near the Chinese coasts, revealing the number and location of all ships in the area, with or without AIS.

This new disruptive technology provides all maritime stakeholders in need of precise and up-to-date information on marine traffic with a new type of data that contributes to a new level of accuracy in maritime domain awareness. The new situation around Chinese shores illustrates the limits of current data sources such as the AIS system and highlights the need for alternatives, such as space-based RF detection, for a thorough picture of human activities at sea.

AsterX, a space warfare exercise that is timely given the situation in Ukraine

Russia's invasion of Ukraine has made us forget it, but France, Germany and Italy have been conducting the second edition of the AsterX space warfare exercise at the Cité de l'Espace in Toulouse since 22 February.

Space warfare: an exercise that has been running since 22 February
Since 22 February, French, German and Italian space soldiers, in cooperation with Cnes, have been conducting a series of virtual exercises simulating attacks on the space assets of France, Germany and Italy. These simulations of crisis situations, called AsterX, have taken on a special dimension since 24 February with Russia's invasion of Ukraine. The reality of the situation may have led the Space Command, headed by General Michel Friedling, to review the scenarios initially planned. The Air and Space Force had initially planned a debriefing for 4 March. It will be interesting to follow in the light of the current circumstances. Unless it has been cancelled in the meantime.

AsterX: a second edition at the right time
The exercise that has been taking place since 22 February is the second AsterX organised by the Space Command. The first edition took place from 8 to 12 March 2021. The novelty of this second edition is that it involves European Union member states, in particular the German and Italian space surveillance centres. In 2021, "it was a military space exercise, which is both a training exercise for space operations and a means of experimenting with a certain number of processes and architectures, to accompany our rise to power", explained General Michel Friedling (cf. Air&Cosmos n°2727).

Private partners involved
The exercise provided training for the CDE's space operators and its operational units, which conduct and monitor French military space operations:
C3OS (Centre de commandement et de contrôle des opérations spatiales), CMOS (Centre militaire d'observation par satellites), located at Creil Air Force Base 110, which ensures the stationkeeping of French reconnaissance satellites and the supply of military space imagery; and Cosmos (Centre opérationnel de surveillance militaire des objets spatiaux), located at Lyon Mont-Verdun Air Force Base 942, for space environment surveillance.

The CPCO (Centre de planification et de conduite des opérations du ministère des Armées), the Dirisi (Direction interarmées des réseaux d'infrastructure des systèmes d'information) and the DRM (Direction du renseignement militaire) were associated with the exercise. Also present were institutional players such as
Cnes (with its operational orbitography centre and one of its station-keeping centres) and Onera, as well as commercial partners: CS Group (for the testing of the first evolution of the space situation monitoring tool), Safran Data Systems (which provides space data from radio frequency detection technology), and ArianeGroup (which manages the GEOTracker optical space surveillance network).

Space Command and submarine cables in this post, (opex360, march4)

French forces in the West Indies (:) ie: French Caribbean) prepare for a possible break in the submarine communication cables


No sooner had the Russian offensive against Ukraine been announced by Vladimir Putin, the head of the Kremlin, than a computer attack targeted the KA-SAT communications satellite operated by the American company Viasat, which provides high-speed Internet access to several European operators, including Nordnet in France.


This was confirmed by General Michel Friedling, head of the French Space Command [CdE], at the latest press briefing of the Ministry of the Armed Forces, to which he had been invited to speak about the second edition of the AsterX exercise. “What we had imagined is happening," he said.


According to General Friedling, it damaged or even destroyed "several tens of thousands of terminals". Incidentally, it also affected the operation of 5800 wind turbines [i.e. a capacity of 11 gigawatts] installed in Germany, which were remotely controlled via the Viasat network. Their terminals cannot be restarted, so they will certainly have to be replaced... Which comes at a very bad time with the shortage of semiconductors. What's more, with the rise in gas prices, Russia, if it is indeed the cause, has in a way killed two birds with one stone.


In any case, this case shows, if it were still necessary, the importance of telecommunications systems. In addition to satellites, submarine cables are also vulnerable. And Russia has been interested in them for quite some time, with the ship Yantar often spotted near those linking Europe to the American continent.


Moreover, French forces are preparing for a break in these submarine communication cables. This could be accidental, as happened to the one linking Guadeloupe to Antigua in December 2020, or it could be deliberately provoked.


This is why the Joint Directorate of Infrastructure Networks and Information Systems [DIRISI], which is probably not talked about enough although its role has become essential nowadays, conducted the TRITON exercise [Tests de résilience interarmées des transmissions] on 23 February.


According to the Armed Forces Staff [EMA], this exercise consisted of "preparing the Armed Forces in the West Indies [FAA] to deal with a cut in its transmissions" to Metropolitan France. The objective was to implement emergency satellite transmission means, simulating a total failure of the transatlantic submarine links.


This exercise mobilised more than 150 military personnel from the DIRISI in Martinique, Guadeloupe and Metropolitan France, as well as those from the FAA operations centre. The Bâtiment de soutien et d'assistance outre-Mer [BSAOM]
Dumont d'Urville and the surveillance frigate Germinal were also mobilised.


In its p ress release, the EMA recalls that the DIRISI must "be able to rapidly set up satellite links to replace the transatlantic submarine links that would be unavailable". This can be vital in the event of a disaster, to enable the FAA to come to the aid of the population.

Not only a debrief of AsterX2022 but a complete overview of the French Space Command assets and capabilities

An excerpt: «ASTERX 22 aimed at training military operators, and at testing and experimenting Command and Control organizations and processes. It also helps sensitize other actors, within the state or outside, to military space issues and train how to operate with them. For instance, the French Armament Directorate (DGA) is part of the exercise, and feedback from the exercise will help define the future systems to be procured.

For the exercise, an orbital population of 10 000 objects is simulated, and 16 events covering all the spectrum of threats are inserted. A mission net connecting all the tools and actors, including Cyber Command, Military Intelligence (DRM, which tasks the observation satellites), the military communications directorate (DIRISI, which tasks communication satellites), CNES, trusted operators and foreign actors (4 other nations involved plus the European External Action Service, which handled a simulated incident affecting Galileo). This is a wider scope compared to last year. A new addition was the Commercial Integration Cell, in which the information provided by commercial trusted operators is collected and summarized.

The exercise simulated 24 days in 6 actual days, and was a success. 27 foreign delegations came to watch it, from 25 countries plus EU and NATO. The envisioned command and control organization was validated, relevant actors were sensitized to a common set of tool, processes and vocabulary, new concepts such as the commercial cell were tested and foreign partners realized the importance of space operations.

AI and satellite imagery, a field of excellence for French intelligence


The large number of satellites orbiting the Earth provide valuable information on major conflicts such as the war in Ukraine. Every day, thousands of these satellite images are recovered by French intelligence services. These images are analysed using artificial intelligence programmes developed by a young French company.

In the field of military intelligence, France has software for analysing satellite images that is considered by international experts to be the best in the world.

The artificial intelligence programmes developed by the young French company Preligens, created in 2016, now enable French intelligence agents to decipher thousands of satellite images in a matter of minutes, whereas these operations used to take several days. These devices are capable, after analysing the images, of issuing alerts on the evolution of a crisis situation. "This software automatically detects all objects of military interest," explains Eve Arakelian, Preligens' Communications and Marketing Director.


Objects detected in a few seconds

"This highly specialised software is capable of detecting objects of military interest in a few seconds on a satellite image. This is why we work exclusively with intelligence. The objects in question can be aircraft, ships, armoured vehicles, anti-aircraft defence systems or the number of tents in refugee camps, in order to estimate the evolution of a crisis situation, for example.

But what is important to understand is that our company has no access to sovereign data from the defence and military intelligence services. And to train our visual recognition algorithms, we buy very high resolution satellite images from, for example, the Airbus Neo and Pleiade constellation or from the American company Maxar. And once trained, we install our artificial intelligence programmes in the computers of the intelligence agents who will use them on satellite images that we have never consulted," continues Eve Arakelian.

We supply our geo-spatial image analysis solutions mainly to France, but we also work with the United States, the United Kingdom, Japan and also with NATO intelligence agencies. Finally, we have developed an equivalent programme within the European Union.


Evidence of massacres

The programmes of the young company Preligens are undoubtedly used to analyse in detail the satellite images of the war in Ukraine. Information that is, for the most part, classified for obvious reasons of discretion, in order to carry out effective counter-espionage operations.

Some of this geospatial data has, however, been published, notably by American news agencies and media, allowing Internet users to examine troop movements and identify tank columns. Satellite images of the conflict have also revealed the extent of destruction in the country and provided the first evidence of massacres of civilians by the Russian military. (deepL)

How Prométhée takes flight

Since its creation in 2020, Prométhée has been burning up the stages. The president of this start-up specialising in Earth observation, Olivier Piepsz, is setting a hell of a pace to get Prométhée to the top of Olympus as quickly as possible. And for the time being, Prométhée is succeeding, both financially and operationally and commercially. Prométhée is really taking off. After raising 2.2 million euros in 2020 and obtaining 800,000 euros in subsidies, this former Safran and Dassault employee has successfully completed his second round (4.72 million) with the aim of scaling up his startup.

"It's a first step, we have a goal of raising 15 million euros this year (in total since the creation, editor's note)," explains Olivier Piepsz in an interview with La Tribune. Thus, Prométhée is already in discussions with so-called strategic partners such as Tikehau and the Provence-Alpes-Côte d'Azur regional council. These investors would be followed by other financial players. This would allow Olivier Piepsz to raise a further 4 to 5 million euros in the middle of the summer. "These investors will be able to help deploy the entire constellation," he says. Finally, between now and the end of the year, Bpifrance [french public investment bank], together with a banking pool, could provide financial support to Prométhée by granting it a seed loan.


First satellite launched in 2023

Prométhée is also in a hurry operationally. It is expected to launch its first multispectral Earth observation satellite ProtoMethe-1 in 2023, manufactured by Lithuanian manufacturer NanoAvionics, which was selected after a competition. "NanoAvionics is super competitive, has excellent technologies and has a good grasp of processes. They are very NewSpace," explains Olivier Piepsz. It was also the only manufacturer that allowed Prométhée to launch a satellite in 2023. This satellite will be the first of its kind and will enable the startup to validate the entire value-added chain it is aiming for - from the satellite to the ground station, including image processing and interconstellation connectivity technologies. All this feedback will be essential for the development of the Japetus constellation, a national programme for which Prométhée has been selected as prime contractor.

The startup is also working hard to launch ProtoMéthée-2, a satellite equipped with a hyperspectral camera, at the end of 2023 or early 2024. The aim is to go as fast as possible," he says. In NewSpace, we are obsessive about being the first and the best. We want to be up there very quickly to confirm our objective of becoming a real operator.


The Japetus constellation

Through the Japetus programme, launched as part of the space recovery plan steered by the General Directorate for Enterprise (DGE) and the CNES, Prométhée wishes to develop a constellation of some twenty nanosatellites with metric resolution thanks to Safran Reosc cameras and above all offering "revolutionary revisit". This means revisiting the same area every three quarters of an hour. "The aim is to be ten times more responsive than at present. We want to offer images all the time and at any hour", stresses Olivier Piepsz. The head of Prométhée also wants to develop "hyperreactivity" to provide customers with images as quickly as possible. "If we are able to offer this service, we will be better than the Americans," says Olivier Piepsz.

In this context, Prométhée proposes that countries acquire space sovereignty by duplicating the model of this constellation and its services. This commercial offer has already attracted ten or so countries with which Prométhée is in negotiations, notably with Nigeria. Last November, the startup signed a letter of intent laying the foundations for a wide-ranging cooperation. (deepL)

French start-up launches its 7th satellite to spot boats that don't want to be seen

Paris, May 3, 2022 (AFP) - French SME Unseenlabs on Tuesday deployed its seventh satellite designed to track uncooperative vessels ("dark ships") from space and thus strengthen the fight against illegal fishing, drug trafficking and marine pollution.
The BRO-7 satellite was put into low orbit by the Electron mini rocket fired from New Zealand, a few weeks after the launch of BRO-6 on 1 April, announced the start-up created in Rennes in 2015.

The satellites in this constellation, which should number 20 to 25 by 2025, pick up radio frequency signals from ships, even if they have turned off their AIS (automatic identification system) transponders.

"We can characterise the emissions, i.e. apply a unique signature to each vessel. This makes it possible to follow their trajectory," Clément Galic, president and co-founder of Unseenlabs, told AFP.

All a ship needs to do at any given moment is to plug in its AIS to get its name and associate it with an electromagnetic signature.

The satellites in orbit, which allow a location to be determined with an accuracy of one to five kilometres, already cover the whole world, so it is a question of increasing the frequency of "acquisitions" when passing over areas of interest, he adds.

"In two acquisitions at most, we can see everything that happens in the Mediterranean. Radio frequency is the first layer of analysis for maritime surveillance. We have an exhaustive vision of a very large area, "100 to 1,000 times larger than an optical satellite", he explains.

According to him, this allows for "optimisation of resources" by assigning optical or radar observation satellites only "to the real areas of interest".

The French Ministry of Defence has made no mistake in investing in Unseenlabs in 2018 through its Definvest fund.

Today, the start-up, which has raised €27.5 million, does more than half of its business internationally.

"We have revenues, we haven't had time to spend it all. More than fundraising, what I would like is a little more French public orders," confides Clément Galic, pointing to the €1.5 billion provided for in the stimulus plan for new space players.

Unseenlabs, which has "gone from 10 to 35 employees in 18 months", hopes to have a dozen satellites in orbit by the end of the year.

"For our part, we are ready to launch several other satellites but this will depend on the availability of launchers," according to Mr Galic. (DeepL)

This is an article entitled: The Indo-Pacific, strategic space of French aerospace power, from which i publish here the part dedicated to the "French spatial forces" (aka "Commandement de l'Espace", CDE):

(…)
The Indo-Pacific and French space policy

The geopolitical approach to outer space is multilateral, because this environment is not susceptible to appropriation by States and escapes their sovereignty. France is nevertheless an important player, with its space industry covering a field ranging from launch (Ariane rocket) to observation and exploration.

A space mission requires three elements: a space segment (the satellite), a ground segment (control centre, earth stations) and a data link segment providing the interface between the control centre and the satellite. In order to be in constant contact with the satellite, the control centre must be able to provide a radio connection with it. The State must therefore build a network of stations judiciously placed around the globe so that the connection between the control centre and the satellite is constant. These stations are essential for controlling the satellite during the stationing phase when the satellite is separated from the launcher, and the station-keeping phase when the satellite is in orbit to make any corrections.

The French overseas territories are a crucial geopolitical asset for French space power. The Kourou launch site in French Guiana, with its proximity to the equator and low latitude, is an ideal location for geostationary satellite launches. The Indo-Pacific area also plays an important role in space observation. A satellite control station is installed in Kerguelen in the French Southern and Antarctic Lands (TAAF) to observe polar-orbiting satellites, which is essential for the observation and electronic monitoring of satellites for military use (CSO*, Pléiades**, CERES***). When the Ariane rocket is launched, the rocket drops the satellite into its final orbit above Kerguelen. It is therefore the station of the Centre national d'études spatiales (CNES) on Kerguelen that recovers the first telemetry. On Kerguelen, 15 to 20 follow-ups are carried out per day, i.e. 600 passages per year.

In addition to the CNES station in the TAAF, a global network of ground stations is also needed to cover the Galileo satellite constellation, the new European geolocation system. This network includes receiving stations, control centres and uplink stations.

In addition to the stations already deployed in Kourou, Nouméa, Sainte-Marie de La Réunion and Papeete, the construction of thirty to forty stations is planned in Saint-Pierre et Miquelon, Terre d'Adélie, Kerguelen, Mayotte, Wallis and the Marquesas Islands. France, thanks to the overseas territories and the Indo-Pacific, is one of the only countries to have a circumterrestrial network of satellite monitoring stations. This network can avoid stormy and temporary negotiations with a third country for the installation of stations.


This geopolitical asset is coveted by several major powers. China, for example, has put into orbit its own GPS-competing geolocation system, the Beidou 北斗 system. No fewer than 30 satellites have been put into orbit for the third version of the programme. However, it is from the Polynesian triangle that the tracking and guidance of these satellites is carried out by a 10,000-ton Chinese navy vessel equipped with trajectory radars: the Yuan Wang 6. The frequent visits of this vessel to Papeete (2011, 2015) testify to this interest.

Outer space, which is essential for military operations, has become a battleground for various actors in international relations. To face this new challenge, France created in 2019 the Space Command (CDE), integrated into the AAE****, whose mission is to protect and defend France's military and civilian interests, as well as those of European space projects. To face the different threats (cyber, electromagnetic jamming, sabotage, kinetic), international cooperation with different partners is essential. In this field, the Indo-Pacific strategy and the defence space strategy of the Ministry of Defence overlap. India, Japan and the United States are described in both documents as strategic partners. Collaboration projects already exist with India (Saral and Megha-trophic satellites), Japan (global dialogue on space) and the United States (French participation in the combined space operations of the US Space Force).

The military surveillance of space objects is also a prerogative of the AAE and the CDE, and this mission is the responsibility of the COSMOS (Centre Opérationnel de Surveillance Militaire des Objets Spatiaux) at Lyon Mont Verdun Air Base 942. Here again, the overseas territories offer several advantages. The overseas territories are less exposed than Europe to ballistic threats, and the periods of sunshine are complementary to those in metropolitan France. An information report by the National Assembly even recommends the creation of a COSMOS antenna in overseas territories, for example in New Caledonia or French Polynesia. In addition to the possibility of ensuring permanent observation, this would send a strong signal of France's involvement in the Indo-Pacific. (…) (DeepL)

NEWSPACE CROCUS PROJECT
Cailabs' laser communications technologies identified as strategic by the European Innovation Council (EIC)


Cailabs, a French deeptech company with a world leadership in light shaping, announces that it has been awarded the EIC Accelerator, a European funding for SMEs. Cailabs will thus accelerate the development and industrialization of its high-speed laser communications solutions.


Rennes, France - CROCUS (Coherent Rapid Optical Communication Under the Stratosphere) is the name of the project led by Cailabs, winner of the EIC Accelerator. This €8.5 million funding will enable the company to consolidate and industrialise its range of laser communication products.

Satellite, naval and airborne communications today rely on radio frequency waves. These are suitable for broadcasts to individuals, but are also limited in terms of throughput and the number of available frequencies, and are easily intercepted. Laser communications allow discrete links, without authorisation, at virtually unlimited rates and are becoming increasingly important in satellite networks.

"It is Cailabs' role to offer turnkey laser communications systems using our unique turbulence compensation technology, which is essential for very high data rates," explains Olivier Jacques-Sermet, Business Development Manager for laser communications at Cailabs. "Cailabs is building its first optical ground station in Rennes via the Keraunos project supported by the French Ministry of the Armed Forces to operate a world first optical link with a nanosatellite. Thanks to CROCUS, we will significantly accelerate our industrialisation and deployment capabilities for operators and system integrators to give them access to satellite links at speeds previously unattainable.


Beyond the acceleration capacity opened up by the EIC Accelerator, this choice validates the technical and economic interest of free space optical networks. As announced by European Commissioner Thierry Breton at the beginning of 2022, the European Union is seeking to consolidate its sovereign telecommunication networks, particularly satellite networks. The choice of the CROCUS project is part of this dynamic and confirms the need of European public authorities to have very high speed and secure optical links that will constitute the core of future satellite networks.

Initiated by the European Innovation Council via EISMEA, the EIC Accelerator is a particularly selective funding scheme (74 winning companies out of 1,093 applicants), which supports strategic European SMEs in their industrialisation and market access. "The EIC Accelerator is a great tool of the European Union that allows SMEs to reach new dimensions" says Jean-François Morizur, CEO of Cailabs. "This funding allows us to accelerate our ambitions by positioning Cailabs as one of the European champions in optical ground stations".

The DGA has qualified the in-orbit operation of the Syracuse 4A military communications satellite

In the night of 23 to 24 October 2021, an Ariane 5 rocket successfully lifted off from the Guiana Space Centre [CSG] with the new Syracuse 4A military telecommunications satellite on board. However, this did not mean that the spacecraft would be immediately operational...

As the first European military satellite to be equipped with plasma electric motors, it took seven months to reach its geostationary orbit at an altitude of 36 000 km. And it was only last May that Thales Alenia Space and Airbus Defence & Space began testing it to verify its performance. This work is now complete.

The French defense procurement agency [DGA] has announced that it has qualified Syracuse 4A for in-orbit operation. "This success is an important step in the progressive commissioning of the Syracuse IV secure military satellite communications capability," it said.

As a reminder, Syracuse 4A is the result of a programme involving the launch of three satellites [Syracuse 4B is due to be launched in 2023, pending notification of the order for Syracuse 4C, provided for in the current military programming law]. It offers a military X-band and Ka-band throughput in the order of 3 to 4 Gb/s [which is three times higher than that of the previous generation of satellites], as well as greater resistance to cyber threats, electromagnetic pulses and jamming. It is also equipped with equipment for monitoring its environment and with the ability to move to counter possible aggression.

"The Syracuse IV constellation will make it possible to cover the French zone of interest, meet the needs of the armed forces in terms of throughput and resilience and support the steady growth in the armed forces' need for telecommunications," the DGA maintains.

In order to exploit the capabilities promised by the latter, the armed forces have ordered 400 "user" stations. "More powerful, more secure and mobile, they will offer the possibility of connecting a greater number of users simultaneously and will enable the forces to communicate in the most isolated areas," explained the Ministry of Defence at the time of the satellite launch.

In addition, via the MELISSA programme, the A330 MRTT "Phénix" tankers will also be able to use the "Syracuse" constellation thanks to satellite stations [COMSAT] compatible with the Syracuse IV constellation but also with any other telecommunications satellite. This will make it possible to turn them into "command and control nodes for air operations".

comments from @stromgade:
Some thoughts on the recent polish announcement that it is working with France on procuring optical satellites.
It's a bit surprising for several reasons:

1) The weather is not great in Eastern Europe in winter, so radar satellites should be preferred to see through the clouds. Indeed, during the cold war the French and German tried to launch such a satellite to surveil Warsaw pact movements.
However, radar images are harder to analyze, and also the leader in radar satellites in Europe is Germany. Maybe for political reasons Poland does not want such a partnership.
There are many recent commercial companies that build small radar satellites, so Poland could still branch into that.

2) French-Polish relations are not great when it comes to weapon procurements. And France is far from the only country building high resolution optical satellites: South Korea, which Poland is buying hundreds of tanks, howitzers and rocket launchers from is one.
So it would seem to be a more likely partner. The other is of course the USA, where @Maxar could have probably sold some 30-cm resolution Worldview Legion satellites.

3) However, the Korean and civilian US options lack one thing that the French offer has: high resolution thermal imagery. Indeed, according to @jdomerchet, Poland wants to acquire two CSO derivatives.
These satellites provide, in addition to sub-30cm visible band images, a thermal infrared channel. That allows them to see at night and likely partly through clouds, making radar satellites perhaps less needed.
Apart from France, the only other option to get such a capability in the short term would be from a US spy satellite (KH-11 or whatever they are called today). But I doubt the US would be willing to sell that.
Since the CSO production has finished relatively recently, the supply chain might be able to spin up relatively quickly to build new copies. Poland seems to be very interested in capabilities available in the short term, that's why they chose South Korean armor.
So in the end even though the announcement was a surprise, there's not much other options if you want to get a very high resolution satellite with infrared capability.
What's funny is that at the start of CSO project, France tried very hard to make other countries join, under the umbrella of the MUSIS project. It initially failed, but eventually Germany bought 2/3rd of a CSO sat, Sweden, Italy and even Switzerland joined the program
and now Poland buying some would make the dream of MUSIS a reality
