This compact, resource-efficient rig can precisely measure a satellite’s speed as it orbits the planet.
Researchers believe it could also serve as a tracking solution for deep-space missions.
With the rise of mega-constellations, traffic management challenges are expected to grow even more severe.
Current methods for tracking satellite speed and position rely on GPS or ground-based radars.
While GPS works when a satellite has a functioning receiver, it can become unreliable during solar storms.
Ground stations, meanwhile, can only track orbiting objects intermittently sometimes just once every few hours or days.
By analyzing this difference, the Spacecraft Speedometer can determine a satellite’s speed and position in real time.
