Lunar Observation Research on Low-Orbit Remote Sensing Satellites

An on-orbit lunar observation method is put forward in this paper aiming at the low earth orbit remote sensing satellite, including observation opportunity, satellite attitude planning and imaging parameters of load, etc. Based on a low-orbit optical remote sensing satellite, the lunar observation experiments were successfully carried out for 8 times in July 2019, and the lunar phase angle covered −79.872–81.657o.The experimental results suggest that the actual performance of satellite attitude is consistent with the designed satellite attitude planning process. Moreover, the method has a high observation efficiency with 1500 s duration. The texture of 8 lunar images obtained have a good sense of layering with clear and stable texture. Furthermore, the spatial resolution is up to 1.18 km. The results verify the correctness and rationality of lunar observation method proposed. It can provide a reliable basis for long-term monitoring of the imaging stability of the remote sensing satellites.
