Quick-response Microsatellite Constellation Design

In response to the task of detecting the target sea area in an emergency, a concept of building a quick-response mi-crosatellite constellation was proposed. Firstly, the two central purposes of the design of micro-satellite constellations were defined, that is, to carry out detailed detection under emergency conditions and to conduct regular long-term visits after the tense situation to the target sea areas; On the basis of the above analysis, the requirements of the observation missions were analyzed concretely from seven aspects: the altitude range of the orbit, the scope of the target sea areas, the return period of the satellite, the imaging resolution requirement of the satellite payload, the coverage requirement of the target sea area, the satellite weight and the satellite lifetime; Then, based on the orbit height design of a single satellite and the constellation design of multiple satellites, the mathematical model of constellation deployment was set up and the micro-satellite constellation of fast response that met the mission requirements was obtained; Finally, the simulation test was carried out. The results showed that the constellation met the design requirements and also verified the correctness of the proposed method.
