Abstract

Compared with the traditional optical remote sensing satellites, SAR (Synthetic Aperture Radar) remote sensing satellites have a short-term high current pulse load, which has a special design requirement for satellite power supply and distribution systems. For low-cost SAR microsatellites, the demand for lightweight power supply and distribution design is more prominent. According to the principles of low cost and high reliability, this paper aims to meet the overall effectiveness and operational reliability of small and micro-SAR satellites. The key points of satellite power supply and distribution system design are analyzed, including power satisfaction, satellite power quality, and temperature of important components such as solar array and batteries. System-level analysis is conducted through topology optimization and isolated double bus configuration, which is verified by engineering in orbit and carried out to provide guarantee conditions for the normalized operation of microsatellite SAR loads.
