VLEO Satellites Operate at Low Altitudes to Enhance Military Tracking and Surveillance, Battling Strong Atmospheric Friction While Seeking More Detailed Images and Intense Signals for National Security.
York Space Systems has unveiled its new LX/V-class satellite platform for missions in very low Earth orbit (VLEO). The design features an elongated shape and narrow solar panels to reduce the surface area exposed to upper atmospheric friction.
CEO Dirk Wallinger stated that the model evolves from the S-class and LX-class families. The company reuses software, flight systems, and attitude control while adapting the structure, propulsion, and solar panels for operational conditions.
The electric propulsion system is supplied by Orbion Space, a manufacturer acquired by York in March. This technology helps maintain orbit and combats atmospheric resistance. The estimated lifespan ranges from three to five years.

Focus on Military Missions and Distributed Space Architecture
The company anticipates that the national security sector will be the primary customer for the new platform. Applications include missile early warning, target tracking, and detection of moving objects, such as aircraft and ground vehicles.
Satellites at low altitudes can observe details more accurately and capture stronger signals with smaller payloads. Wallinger indicated that the equipment will integrate into layered defense networks, operating alongside spacecraft situated in higher orbits.
This initiative aligns with the trend of distributed constellations, where multiple small satellites work together instead of relying solely on a few large units. The architecture enhances resilience and enables continuous responsiveness.
Previous Tests in Low Orbit Validated Project Technologies
York utilized data from the Bane demonstration satellite, launched in December 2023, on the S-class platform. The vehicle tested navigation, resilient positioning from CACI, and optical communications by being reduced to about 200 kilometers in altitude.
Even under intense atmospheric friction, the spacecraft maintained attitude control and communication capability. The results provided the necessary operational data to modify the existing family of satellites without requiring a complete redesign.
The reuse of proven technologies shortens the factory development time. Consequently, the company claims to be prepared to swiftly meet customer demands for new low altitude surveillance and tracking capabilities in space.
