Abstract:

Space camera imaging parameters are often subject to satellite platform resource constraints, which can not all be sent to the camera from the ground, Instead, the satellite platform selects ground calibration parameters saved in the camera according to gear selection. Because of the space environment, TDICCD uniformity will change during the space camera work in-orbit, thus affecting the image quality. It is necessary to design a method of re-injection of imaging parameters for an off-axis space TDICCD camera in-orbit. First, the camera work platform is introduced, and the design of imaging parameters re-injection in orbit is determined. Then, the program to receive, save, check and write the data is described. Finally, in order to prove the validity of the method, a software-specific detection module for camera controller is used, and the comparisons of TDICCD pictures before and after the imaging parameters modification are presented. Experimental result shows that the imaging parameters modification is successful.

Key words: in-orbit re-injection, camera controller, space camera, TDICCD, remote sensing imagery
