摘要

An image motion compensation method is proposed for the SDLT-1 satellite of China and an experiment based on the three-axis air-bearing physical simulator equipment is designed to testify the feasibility of the proposed method. The experiment shows that the deviation of the LOS after AMC compensation can reach 10.96urad ( \(3\sigma\) 3 σ ) and 97% deviation of the LOS can be compensated by the proposed method compared to the result before AMC compensation 313.5urad ( \(3\sigma\) 3 σ ).
