Satellite Surface Contamination (OSC) has unneglectable effects on solar-array output power, connections between solar-array, thermal blanket's functions, payloads' and optical sensors' performances onboard the Low Earth Orbit (LEO) satellites (especially long lifetime satellites). It can even influence their actual life. There are many kinds of examples in our country and overseas. In order to ensure satellites for long time working normally, we have set out to monitor and analyze the satellite surface gas. To be an effective instrument, Satellite Surface Gas Component Detector (SSGCD) is used to monitor the "in-situ" surface gas for the emergence and the variety with the change of time and position, as well as to monitor and identify the gas component and its density. Through the data processing with Ground Data Processing Unit (GDPU), we can evaluate the degree of the influence resulted from OSC, and provide services for orbital fault analysis and disposal.
