Reach on the measurement of the terminal performance of space laser communication system

Abstract

Space laser communication system uses laser light as the information carrier to achieve intersatellite communication. And the terminal of laser communication is the key part. It is necessary to accomplish the test of performance and function, validation and judgment. The test of dynamic and static performance for terminal is the basic content and necessary steps on the reliability of space laser communication terminal. So the reach on ground test technology of space laser communication is more important. This paper mainly describes the test system of integrated performance for space laser communication terminal. The test range of system includes two essential parts, i.e, static test and dynamic test. Static test includes the angle of divergence, the coaxially of axis, communication performance and so on. Dynamic test includes the test of capture ability at dynamic and disturbance environment, and the test of dynamic track precision. The test system has achieved accurate test of dynamic track precision and multi-performances test of terminal based on simulatin at real working environment. The test result could present the anti-disturbance performance, anti-noise performance, and dynamic communication performance of the terminal.
