Paper Abstract

In this paper, a prototype of intersatellite laser communication terminal for a principle demonstration is reported, and the corresponding ground support equipments are described, too. The terminal has two main subsystems, the first is one for the laser communication and the second for the pointing, acquisition and tracking. Laser diodes are used for the communication link, and with the average laser power of more than 200mW and the data-rate up to 600Mbps. The PAT unit consists of a fine pointing mechanism and a coarse pointing assemble, which reaches a tracking accuracy of ~5μrad. The on-ground test equipments are included in a communication test bed with a long-distance beam propagation simulator, a PAT test bed with an optical satellite trajectory simulator, and a wavefront test bed with deferent lateral-shearing interferometers.
