Abstract
In order to improve the positioning accuracy of high resolution remote sensing satellite without ground control points,
the accuracy of payload pointing determination must be improving. In this paper, the development of high accuracy payload pointing determination technology of satellite is introduced, and the main methods that achieve high accuracy are analyzed. There are two implementations, one is the highly stable structural design and the integrated configuration design which provides common installation reference for both attitude sensors and payloads, the other is measurement of the relative changes between the attitude sensors and the payloads in orbit and to achieve high precision payload pointing determination by compensation processing. Based on the investigation results, this paper proposes a pointing determination system design for multiple payloads, which realizes the high precision transmission from the measuring sensors to the pointing monitoring payloads from the system level, and can solve the pointing change caused by the internal changes of payloads such as the camera and LIDAR system. The design method can provide a reference for the future development of the satellite with high performance.
