A software suite for orbit determination in Space Surveillance and Tracking applications
, 2022 In the last decades, the growing in-orbit population of resident objects has become one of the main concerns for space agencies and institutions worldwide, and several initiatives have been promoted to tackle this issue. In the resulting Space Surveillance and Tracking (SST) services, ground-based sensors (optical or radar) are typically used to track ...

Cooperative Tracking Strategies for Optical Space-To-Space Surveillance Constellations
IAF Space Operations SymposiumMost space surveillance and tracking systems are constituted by networks of ground stations of observing radars and optical telescopes. These systems are usually reliable, easily serviceable, and effective under ideal conditions, but suffer from strong bounds on scalability and coverage due to the heavy constraints on their geographic locations ...
