Description

technical field [0001] The invention relates to the technical field of spacecraft testing, in particular to a Mars elliptical orbit image motion compensation control ground verification system. Background technique [0002] Mars exploration requires the use of high-resolution cameras to complete high-resolution imaging of key areas of Mars. The remote sensing orbit of Mars is an elliptical orbit with precession. Because Mars is far away, the accuracy of orbit determination is relatively low compared with that of near-Earth satellites. Under this condition, it is difficult to achieve 0.5m resolution imaging of the near-fire arc. At the same time, precise image motion compensation control is required during the on-orbit imaging of the Mars High Resolution Camera. Since the Mars high-resolution camera itself does not have a bias current adjustment function, it can only complete the image motion compensation function of the high-resolution camera by sending a bias current adjus...
