Paper Abstract

Ring Laser Gyroscope (RLG) is a kind of typical inertial device widely used in navigation field. Owing its recent advances, RLG is proposed to be used as angle measuring instrument with highly dynamic performance and loose installation requirement. To prove the reliability of RLG’s angular measuring result, the metrological performance of RLG was analyzed through calibration. A new calibration method was studied to separate RLG’s additional error resource such as bias drift. The special calibrating procedure was designed and the corresponding calibration system was set up. The calibration result shows that the RLG angular measuring system has measuring deviation within ±0.4″ and repeatability within ±0.2″. The study proposes an effective calibration method of RLG’s metrological performance and proves the possibility of RLG’s application in high accuracy in-situ metrology field.
