Lessons Learned From Technology Demonstration of Space Situational Awareness Satellite
As the number of Resident Space Objects (RSOs) increases in orbit, the risk of collisions increases. As a result, action needs to be taken to properly detect, identify, and track what objects are in view at a certain time which is an area of research ...

Executive Brief: OD-SSA v2.0 Constraint-Based Orbital Debris Space Situational Awareness
Multi-phase strategic infrastructure addressing three critical Space Situational Awareness failures: (1) 500,000-1,200,000 object blind spot - 1-10cm debris fragments create major mission-ending risks but 0% cataloged (current threshold ~10cm); (2) 100,000-maneuver-per-year unpredictability crisis - Starlink executes 50,000 collision avoidance ...
