Abstract: This paper introduces the satellite system running status and key events. This satellite has been observing the Earth for six years after its launch into a 645 km sun-synchronous orbit. Through the health trend analysis of the platform and subsystems, the orbit, power supply, rotating parts status, temperature, fuel consumption and so on are introduced in detail. The cameras’ status also are monitored and analyzed.

Key words: health trend analysis, image quality monitoring, satellite
