Research on Task Scheduling Algorithm of Widerange High-resolution Remote Sensing Satellite Constellation for Emergency Disaster Reduction

To address the task scheduling problem of wide-ra nge high-resolution remote sensing satellite constellations for eme rgency disaster reduction, a spatio-temporal demand matrix for r emote sensing tasks was proposed.A remote sensing task scheduli ng algorithm based on moving candidate strips was designed on t his basis. Through simulation, the spatio-temporal demand matri x can flexibly describe the spatio-temporal requirements of differ ent remote sensing tasks. The remote sensing observation scheme can be generated through the adaptability of the scheduling algor ithm, which can basically meet the requirements of emergency dis aster reduction tasks.
