Building and Application for China Songshan Artificial Target Site

The Chinese first target site for satellite remote sensor on-orbit performance assessment,Songshan Artificial Target Site,was built in Henan Province,China in September of 2013.This site can be used for high-resolution satellite remote sensor performance measurements such as modulation transfer function(MTF),GSD,linearity,dynamic range,radiometric resolution and absolute radiometric calibration.The overall plan,design and implement of the Songshan Artificial Target Site are presented.The results of GF-1 satellite in orbit MTF measurement based on the Target Site are introduced,and the site applications are suggested.
