A Resource Scheduling Algorithm for Optical Ground Stations Supporting Satellite Observation Tasks

To address the resource scheduling problem of ground-based optical stations for key space target observation, this study proposes a station-structured genetic algorithm driven by dual-level tabu memory. The proposed method integrates station-grouped encoding, heuristic initialization, station-structured crossover, neig...

Spacecraft Orbital Maneuver Detection Using Adaptive Multi-Feature Criteria

To address the unstable detection of weak orbital maneuvers from publicly available Two-Line Element (TLE) data affected by natural perturbations, orbit-determination errors, outliers, and irregular update intervals, an adaptive multi-feature maneuver-detection method is proposed. The method incorporates a dominant J2...
