Emergency Constellation Design Based on Micro SAR Satellites

According to the requirements of all-weather emergency remote sensing applications such as disaster prevention and earthquake rescue, high-revisit constellation design and performance simulation based on micro SAR are carried out. A microsate1Ute SAR constellation consisting of 7 orbiting planes and 35 orbiting satellites is constructed. The constellation can be revisited within 2 hours in any region of the -world to meet the needs of all-weather remote sensing applications such as disaster prevention and emergency rescue. The constellation design method provides a solution for the future low-cost, integrated, intelligent and networked micro satellite constellation system.
