Analysis of aberration effect on high orbit satellite laser ranging

Due to the development of the satellite laser ranging technology, high orbit satellite laser ranging data volume increases significantly, but high orbit satellite has weak echo signal due to the distance, which requires the telescope system to align satellite accurately in order to receive the valuable echo signal. In this paper, the main factors that affecting the telescope to aim were analyzed, namely satellite velocity aberration and flight-time aberration of laser pulse. Based on Glonass series high orbit satellite as an example, the aberration offset was mainly studied, introduced laser operation, and the station measurement of Glonass satellite series aberration angle offset of 26 rad was calculated, and in the actual series of Glonass satellite in high orbit satellite laser ranging dozens of times ranging experiment verification. In this paper, it proved that optical line difference influences analysis is correct. Through the research we can improve the capture probability of high orbit satellite laser ranging and greatly enhance the efficiency of observation.
