Abstract
In the face of increasingly frequent regional emergency missions, the use of small satellites to obtain spatial information in hotspots has important practical needs. Under the premise of avoiding the short coverage of single satellites and limited access to information, this paper aims at research on the design and optimization of multi-satellite network orbits covered by hotspots regions. Firstly, based on the analysis of satellite coverage characteristics, the satellite coverage model is established, and the coverage calculation and coverage judgment conditions are discussed. Then a genetic algorithm based regional coverage satellite network design and optimization algorithm is proposed, which is designed the coding method, algorithm flow and corresponding constraint test rules in detail. The rationality, feasibility and effectiveness of the algorithm are finally verified by simulation examples. are provided, which provides a useful reference for regional space missions and its certain theoretical significance.
