Description

technical field [0001] The invention relates to a satellite optical communication device, in particular to an advance aiming compensation device in the satellite optical communication device. Background technique [0002] The distance of signal transmission in inter-satellite optical communication is very long, which makes the relaxation time of transmission longer. When considering the relative motion between two satellites, the transmitting end must actually aim the beam to the "front" of the receiving end so that the receiving end can receive the signal. That is to say, when aiming, the transmitter must take into account the additional movement between the two stars that occurs during the beam transmission relaxation time, so as to align to the expected angular position. This aiming process is usually referred to as aiming in advance. The principle of the existing angle compensation device for advance aiming is to predict the value of the advance aiming angle at the cur...
