Micro/nano-remote sensing satellite network(MN-RSSN)composed of a lot of micro/nano-satellites can observe earth with high spatiotemporal coverage.However,the difficulty of conflict resolution increases rapidly as well.As for this problem,the work pattern and con-straint conditions of the observation on the earth by MN-RSSN are analyzed.Aimed to large area targets are oriented,a period-driven earth observation requirements planning method for MN-RSSN is proposed.Based on the real satellite orbit data and simulation tools,the coverage performance of planning results from the application examples of Sichuan province is simulated and analyzed.The method simplifies MN-RSSN work pattern of earth observation.Area targets can be observed for several times and data basis is established for improving the ob-servation quality of earth by MN-RSSN.
