Efficiency Simulation of Space-based Natural Disaster Surveying System
The earth remote sensing satellite system plays a crucial role in emergency management and disaster prevention and mitigation systems,primarily serving to rapidly and accurately provide essential information such as the extent of damage and conditions in disaster-stricken areas following an event.This study focuses on the disaster survey scenario of earth remote sensing satellite system,systematically sum-marizing the development process of its satellite constellation.Based on the current configuration of Chi-na's earth remote sensing satellite constellation,STK software is employed to construct a simulation sce-nario for post-disaster surveys.The effectiveness of the system in assessing disaster areas is analyzed from three perspectives:coverage percentage,average coverage gap,and average access time.The simulation results can serve as a reference for enhancing China's emergency satellite constellation construction and emergency command decision-making.
