摘要	A high-resolution remote sensing satellite with a large ground swath width requires on-orbit compensation of the drift angle. However, there are large differences between drift angles of different positions on the focal plane. According to the research status, this paper proposes to compensate the average drift angle by satellite yaw angle adjustment, after which the focal plane adjustment mechanism in the camera can be used to eliminate the residual error. In this paper, drift angle calculation and the compensation method for a high-resolution, wide-range space camera were conducted. For further improvement of the compensation precision, a high linearity motion focal-plane adjustment mechanism was designed according to the drift angle. Theoretical calculation and nonlinear residual analysis of the mechanism motion were carried out and verified by laboratory tests. Test results showed high motion linearity of the mechanism and were in good agreement with the theoretical analysis results. Finally, MTF analysis was carried out and showed that the nonlinear error of the mechanism contributes little to MTF reduction and is small enough to be neglected. The MTF reduction decreases by 42.9% after mechanism further compensation of drift angle, and the result satisfies the imaging quality requirement of TDICCD. (C) 2020 Elsevier Ltd.
