| 摘 要： | 本文介绍国外研制环形激光陀螺(RLG)的经验和现状,把误差产生机理及其补偿方法作为研究重点,这是取得成果的基础。机械抖动偏频技术有优点,得到了广泛应用,但在精度上尚不能满足精密惯性导航的要求。近年来国外正在研究的速率偏置技术显著地降低了RLG的随机误差,并可补偿常值漂移。本文讨论了这一技术的优点。

| Abstract: | The parper describes the experience and present status in developirg ring laser gyro at abroad. Successful results have been obtained in research and development, which are based upon the error analysis and their compensation methods. Mechanical dither for frequency biasing has some adventages and has been applied widely, but it can not meet the accuracy requirment in inertial navigation. Recently at abroad rate-biastcchnique is under development, it can reduce the random error oi RLG significantly and compensate its bias drift rate. The adventages of this technique are discussed in the paper. |
