Abstract:

Aiming at the three prominent issues encountered in practical telemetry, tracking and control and data transmission scheduling, namely the integrated scheduling of telemetry, tracking and control and data transmission, the low efficiency of large-scale satellite resource scheduling, and the equipment resources fragmentization after scheduling, an optimization model for integrated telemetry, tracking and control and data transmission resource scheduling is established. Two optimization objectives, namely task satisfaction rate and idle resource fragmentation number, are proposed, and a three-stage heuristic solution algorithm is designed.The algorithm first generates an initial scheduling solution, then combines a backtracking search mechanism with heuristic strategies such as tabu list and random search to improve the task satisfaction rate. Finally, by establishing a feasible solution decision function, resource allocation is optimized to reduce the number of idle resource fragments. Experimental results show that compared with existing benchmark algorithms, the algorithm improves the solution efficiency by at least 4 times, increases the task satisfaction rate by at least 3.13%, and reduces the number of idle resource fragments by at least 18.05%, thereby validating its fundamental efficacy in resolving the tightly constrained joint scheduling of telemetry, tracking and control and data transmission

Key words: integration of telemetry, tracking and control and data transmission, resource scheduling, idle resource fragmentation, heuristic algorithm
