Paper Abstract

This presented paper describes a high-precision goniometer system with a ring laser gyro (RLG). The principle of the goniometer is introduced. The key techniques for improving the measuring accuracy are analyzed. As the central element of the goniometer, RLG is investigated, including its error items, such as scalefactor, bias and random walk coefficient. The experimental results are provided.
