Paper Abstract

Aiming at the problem of lightweight and miniaturization of satellite optical communication terminals and intersatellite optical communication in multi-layer satellite networks, The beaconless light tracking and acquisition technology in satellite optical communication is researched and analyzed. The link margin of the satellite laser link under direct detection mode is analyzed , the track and the capture process is designed, the influence of satellite platform attitude error, inter-satellite link communication distance and other factors on capture time and capture probability are simulated and analyzed. The scheme designed uses the active side to emit signal light to scan the FOU, and the passive side uses the capture. The way the detector gaze is captured, ie the gaze-scan capture method. The research shows that in the designed multi-layer satellite network optical communication scenario, the acquisition time of GEO satellite to MEO satellite and GEO satellite to LEO satellite communication is 2034 seconds and 351 seconds respectively, and the capture probability is 95.28% and 99.99% respectively. The acquisition time of MEO satellite and LEO satellite communication is 216 seconds, and the probability of capture is 87.32%, which can meet the requirements of optical communication links of different orbit satellites in multi-layer satellite networks.
