Checking Image-linetime Relationship for TH-01 Satellite

doi:10.13474/j.cnki.11-2246.2017.0180

Abstract

Abstract: The TH-01 satellite is a transmission type mapping satellite,it's able to realize global precise positioning without ground control point.However, precise satellite attitude and orbit parameters of every photographing time line are required in post process. Linetime data in archived satellite product actually serve as a bridge between image data and attitude and orbit data. We analyze the intrinsic relationship of image data,linetime data and auxiliary data, and the experiments demonstrate the influences of mismatch of 1A image and timeline data on positioning precision. Then, we propose an approach to checking the matching attribute of 1A image and timeline data. Processing results validate the availability of the proposed method.

Key words: TH-01 satellite, stereo mapping satellite, attitude, orbit, linetime data
