Embodiment Construction
[0051] The on-orbit calibration of the satellite optical communication terminal and the method for calibrating the coaxiality of transmission and reception of the present invention will be described in detail below with reference to specific embodiments and FIG. 2 .
[0052] In order to realize the functions of on-orbit self-calibration and optical axis correction of satellite laser communication equipment, the on-orbit self-calibration of the satellite optical communication terminal of the present invention mainly revolves around the calibration of the receiving optical axis position of the beacon laser and the signal laser and the correction of the transmitting optical axis position Two aspects, according to its working process, can be divided into two stages, that is, the stage of externally calibrated receiving optical axis and the stage of internally correcting emitting optical axis.
[0053] 1) External calibration receiving optical axis stage
[0054] 1.1) The ground sa...
