Optimization of Measurement for Earth’s Surface Based on Satellites Data

Abstract

In this study, an optimization model of coverage performance (OCP) are proposed to measure the Earth and describe the interactions between satellites and the Earth. In OCP, the coverage width of Footprint and the periodic regression of satellite are main factors to the coverage performance. Therefore, the optimal scanning time for satellite is determined based on these two factors. The proposed method is applied to FY-1 Meteorological Satellite to verify the efficiency of the optimization model of coverage performance. The results show that the time needed for FY-1 Meteorological Satellite to completely measure the whole Earth is 25 days. The method proposed can provide the references for decision makers.
