摘要

The characteristics of the terminals for the inter-satellite laser communication must be tested and verified on ground before flight test. A pair of terminals for inter-satellite laser communications was developed for principle demonstration. A terminal has two main subsystems. The first is one for the laser communications and the second one for acquisition, pointing and tracking (APT). The optical methods and related system test-beds to measure and verify the performance of the terminals in the lab room. In these programs, several novel ideas are proposed. With these ideas, whole programs can be tested on ground in near-contacted field. The dynamic APT performances of an inter-satellite laser communication terminal can be tested and verified by the combination of satellite trajectory simulator and a collimator-like laser communication.
