Belgium invests €200 million for first sovereign military satellite constellation under GALO program.

On July 15, 2026, Defense Minister Theo Francken announced that Belgium will invest over €200 million to deploy its first sovereign military space-based Intelligence, Surveillance and Reconnaissance (ISR) architecture, named the GALO (Global Coverage All-weather Low Earth Orbit Observation) constellation, according to L'Echo. The project aims to reduce Belgian strategic dependence on foreign imagery, particularly France's CSO optical reconnaissance satellites, by granting Brussels direct control over orbital tasking schedules and revisits. The constellation will field an initial capability of approximately 10 Low Earth Orbit (LEO) satellites by 2027 before reaching full operational status by 2030.

The €200 million GALO program will deploy a mixed constellation combining electro-optical and Synthetic Aperture Radar (SAR) Low Earth Orbit satellites to enable all-weather, sub-meter resolution intelligence gathering across priority operational zones. Managed operationally by the Belgian Air Force Space Security Centre and the ADIV intelligence service, the procurement leverages local defense industrial partners, including Aerospacelab and Redwire Belgium, alongside commercial launch providers.

On July 15, 2026, L'Echo announced that Belgium will invest more than €200 million in its first sovereign military space-based Intelligence, Surveillance and Reconnaissance (ISR) architecture. Named GALO (Global Coverage All-weather Low Earth Orbit Observation), these military satellites will reduce the country's dependence on French and allied satellite imagery. Initial capability is planned from 2027, with full operational capability targeted for 2030. The first deployment phase is expected to involve roughly 10 Low Earth Orbit (LEO) satellites, before potentially growing to several dozen spacecraft distributed across multiple orbital planes, as a single satellite passing over a target at approximately 7.5 km/s can observe it only during a few tens of seconds to a few minutes before continuing.

The Belgian Air Force Space Security Centre will likely coordinate the programme. At the same time, ADIV, Belgium's military intelligence service, will probably define intelligence requirements, exploit the collected data and distribute the resulting products to Belgian and allied commands. The GALO programme addresses a specific limitation in Belgium's current intelligence model. Belgian authorities can request access to French military imagery, particularly from the CSO optical reconnaissance system. Still, they do not control the satellite's collection schedule, emergency tasking sequence or allocation of observation time. Defence Minister Theo Francken indicated that Belgium may currently obtain coverage of selected areas for only a few minutes per day.

That is sufficient for occasional strategic assessment, but not for routinely following mobile targets, monitoring several crisis zones at once or repeatedly checking whether activity has changed at an airfield, logistics hub, border crossing or military camp. During a major NATO or French national operation, Belgian requests would compete with French, alliance and European priorities for the same limited collection windows. GALO is intended to give Brussels direct control over target selection, collection timing, revisit frequency and dissemination, while allied and commercial imagery would continue to supplement the national system rather than disappear from the Belgian intelligence architecture. The most expensive and operationally demanding part of GALO may not be the satellites themselves, but the ground and exploitation infrastructure required to turn sensor data into usable intelligence.

Belgium will need a mission planning force to translate government and military priorities into collection requirements, a tasking centre to assign those requirements to specific spacecraft, a satellite control centre to manage orbital operations and spacecraft health, ground terminals to receive data, and a secure archive capable of storing large volumes of optical and radar imagery. It will also need imagery specialists, geospatial analysts, target databases, automated change-detection software and networks able to share data rapidly to national headquarters, deployed forces and NATO systems. A constellation can generate large numbers of images, but without automated filtering most of that volume would overwhelm a relatively small intelligence service.

AI-based object detection could flag aircraft, ships, armoured vehicles, new trenches, construction activity or unusual movement, while human personnel would still be required to verify the result, evaluate possible camouflage or deception and determine its operational significance. The Low Earth Orbit (LEO) gives Belgium lower latency, smaller spacecraft and potentially sharper imagery than higher-altitude systems, but it also creates the need for numbers. A satellite operating between about 400 and 700 km altitude completes one orbit every 90 to 100 minutes, although it does not pass over the same target on every revolution because Earth rotates beneath the orbit. Consequently, one optical satellite may revisit a location every one to three days.

Two satellites could reduce the interval to roughly 12 to 24 hours, five could permit several observations per day and a constellation of about 10 could potentially reduce access intervals to a few hours over selected regions. A force of several dozen satellites could bring revisit times below one hour over priority areas if the spacecraft are correctly distributed across multiple orbital planes. These are planning estimates rather than guaranteed performance because actual results depend on cloud cover, sensor type, viewing angle, competing tasking requests and ground-station access. This overlap gives enough repeated observations to detect movement, compare changes and hand off a target to another sensor before the intelligence becomes obsolete. 

The word "All-weather" in GALO indicates that Belgium will almost certainly need both electro-optical and Synthetic Aperture Radar (SAR) satellites. Optical sensors provide the clearest visual identification of aircraft, vehicles, buildings, weapon positions and battle damage, but they are constrained by darkness, cloud, fog, smoke and atmospheric conditions. SAR satellites transmit microwave energy and measure the reflected signal, allowing collection at night and through most cloud cover. Depending on sensor design and imaging mode, SAR resolution can range from around 3 metres for wider-area surveillance to approximately 0.25 metre for narrowly focused collection. Radar imagery is especially useful for identifying changes in soil, newly built field positions, vehicle concentrations, bridge use, ship movements, flood conditions and terrain deformation.

It is less intuitive than a conventional photograph and requires specialist interpretation, but repeated SAR passes can reveal activity that optical imagery misses entirely. A mixed constellation would allow radar satellites to detect that something has changed and optical satellites to determine more precisely what is present when weather and lighting permit. Image resolution will determine which military questions GALO can answer. Imagery at 3 to 5 metres per pixel can locate major roads, buildings, runways, ports and large ships, but it cannot reliably distinguish individual armoured vehicles or artillery systems. Around 1 metre, analysts can generally separate tanks, aircraft, missile launchers and artillery pieces from surrounding objects. At 30 to 50 centimetres, imagery can support recognition of vehicle types, radar layouts, engineering works and individual aircraft parked on dispersal areas.

In the 20 to 30-centimetre range, it becomes possible to examine smaller equipment features, camouflage arrangements, weapon positions and some differences between vehicle variants, although atmospheric conditions and viewing geometry still affect usable quality. Belgium has not published a formal ground-sample-distance requirement, but routine military identification, target confirmation and battle-damage assessment would normally require at least sub-meter optical capability. Higher resolution will increase payload size, pointing accuracy, data volume and processing demands, creating a direct trade-off between image detail, spacecraft cost, field of view and revisit frequency. The announced €200 million should be treated as an entry cost rather than the full price of a sovereign military space capability.

The figure must cover some combination of satellite development, production, payload integration, launch services and initial ground infrastructure, but recurring expenditure will continue after 2030. Low-orbit satellites may need replacement after several years because of component ageing, solar radiation exposure, propulsion limitations and atmospheric drag, while sensors and onboard processors will become obsolete more quickly than those on traditional 10-to-15-year reconnaissance satellites. Belgium will also have to fund operators, imagery specialists, software licences, secure communications, data storage, cyber protection, orbit maintenance, collision avoidance, replacement launches and periodic upgrades to AI-processing tools. Over a 10-to-15-year period, full programme expenditure could therefore reach several times the initial allocation, although no Belgian life-cycle estimate has been released.

The distributed model nevertheless allows investment to be spread over successive production blocks, with newer satellites replacing older ones and introducing improved payloads without grounding the entire capability. But the Belgian industry is well positioned to capture work in spacecraft production, integration and ground exploitation, even if launch services will remain foreign. Aerospacelab's Charleroi facility, for instance, is designed to produce up to 500 small satellites per year, giving the company capacity far beyond Belgium's national requirement, while allowing serial production. Its relevant capabilities also include satellite buses, optical payload integration, constellation operations and manufacturing at scale. Redwire Belgium is already leading MATTEO, Belgium's first security satellite demonstrator, with Aerospacelab participating in the programme.

MATTEO can test secure mission operations, national command arrangements, spacecraft control and industrial cooperation before GALO expands to a larger constellation. Belgian companies could also compete for encrypted communications, onboard electronics, imagery processing software, data fusion, ground control, secure cloud infrastructure and cyber defence. Belgium has no domestic launch site, so spacecraft will probably be placed into orbit by foreign providers such as SpaceX or European launch operators, either in batches to establish orbital planes or individually to replace failed and ageing satellites. GALO's military value will also depend on whether its products are connected to Belgian combat and command systems rather than confined to an imagery center.

F-35A mission planners could use satellite data to update threat locations, examine airfields, identify radar and surface-to-air missile deployments, verify targets and assess strike results. MQ-9B SkyGuardian crews could be directed toward coordinates where satellites have detected new activity, allowing the drones to maintain persistent surveillance after the satellite has passed beyond the area. GM200 radars could provide time-sensitive air tracks, while satellite imagery could show the supporting airfield, logistics site, launcher location or dispersal pattern associated with those tracks.

NASAMS and Skyranger 30 units would not normally receive raw satellite imagery directly, but operational headquarters could use GALO data to position batteries, monitor likely launch sectors and update the wider air picture. In Africa, the constellation could monitor Belgian deployment areas in the Democratic Republic of the Congo, follow armed group movement in the Great Lakes region, examine convoy routes and border crossings in the Sahel, and contribute to ship detection and port monitoring in the Gulf of Guinea. By 2030, the programme's success will likely be measured by collection frequency, processing time, target recognition accuracy, archive depth, network availability and the number of operational decisions supported, rather than by the number of satellites launched alone.
