摘　　要：介绍了东方红三号卫星的速率积分陀螺的基本工作原理和性能指标, 描述了速率积分陀螺的数学模型。分析了东方红三号卫星陀螺在轨飞行四十天中的常值漂移标定和补偿的结果,The basic operation principle and performance parameters of the rate integrating gyro (RIG) of the DFH-3 satellite are presented in the paper. The mathematical model of the RIG is constructed. The results of on orbit calibration and compensation of the constant drifts of the RIG of the DFH-3 satellite during flying of 40 days are analyzed, then the availability of the RIG made by BICE and the accuracy of the two calibration methods are proved out.
