Watchdog
A maneuverable guard spacecraft designed to hold position near high-value satellites, watch nearby activity and move to respond to threats.
Why it matters
Military and commercial satellites can be approached, inspected or interfered with by other countries' spacecraft. Cheap guardians that can see and react nearby give owners an option besides watching from the ground.
How the technology works
Fortastra's spacecraft are designed to hold position near a critical asset, assess activity around it and respond in real time. Watchdog V0 has launched, and the company calls it an initial operational success.
Its Series A pays for relative navigation, a real-time perception system and a modular bus built for high-rate production.
