Robust Divergence Angle for Inter-satellite Laser Communications under Target Deviation Uncertainty
2023 IEEE 98th Vehicular Technology Conference (VTC2023-Fall), 2023 Performance degradation due to target deviation by, for example, drift or jitter, presents a significant issue to inter-satellite laser communications. In particular, with periodic acquisition for positioning the satellite receiver, deviation may arise in the time period between two consecutive acquisition operations. One solution to mitigate the issue
