Abstract: The traditional ground-based method has a low cost-effectiveness and large uncertainty of single experiment, which can not meet the requirement of high frequency and high-precision radiation performance change monitoring of satellite payloads. A based on automated method is applied on radiometric performance change monitoring of GF-6 pan multi-spectral sensor(PMS) based on the Dunhuang radiation site (hereinafter referred to as "Dunhuang site"). The results show that decay of radiation performance is less than 5% since GF-6's launch.

Key words: GF-6 satellite, automated technology, radiometric performance, change monitoring
