In order to simulate the effect of orbital motion on the laser communication terminal′s PAT system performance, a high precision one dimensional turntable was developed. GEO-LEO and LEO-LEO satellite relative motion angular velocities were analyzed, and the requirement of turntable′s angular velocity range was proposed accordingly. Based on the digital control technology, compound control and high level input cascade compensation were used to achieve the stable control with super-low speed. To meet high precision demand in angular location accuracy measurement, the influence of adjustment and alignment error in test procedure was studied. According to the results, the max turntable angular velocity was 2 (°)/s; the angle position measurement error of adjustment and alignment error could be ignored; the actual turntable position precision was superior to 2.5″. The turntable meets the requirements of high-precision and low-speed for the orbital simulation of space laser communication terminal.
