Analyse of Axis-Errors and Compensating in Terminal of Intersatellite Optical Communication;

In this paper,it analyzes the consistent of a system of intersatellite optical communication, main components, key technology, developing trend and main problems of subsystems.

Selections of acquisition scan methods decide the acquisition performance of a terminal in intersatellite optical communications under the same external conditions and system parameters.

Study on the measurement of tracking and pointing accuracy used for the terminals of free space laser communication;

Analysis of the far field distribution measurement of the terminals of free space laser communication and de of the measuring system design;

Using a beacon in the free space laser communication system is an important method of finishing the acquisition course.

Both transmitter′s and receiver′s pointing errors cause signal fade in optically preamplified laser satellite communication,it is important to optimize the system performance in the presence of both the transmitter s and the receiver′s pointing errors.

This paper discusses the coupling loss induced by pointing error of receiver for coupling space light into single mode fiber in laser satellite communication systems with optical preamplifiers.
