摘要
针对陀螺漂移和加速度计零偏,提出了一种三位置现场测试方法。该方法不需要转台,对夹具和测试基准无特殊要求,惯性组件无须精确取向。仿真结果表明,惯性器件测试误差主要由安装失准角和标度因数误差有关。
Aimed at the gyro drifts and the accelerometer biases,a good solution which is a test under three position condition is presented. It needn't rotary table and special requirements on fixture and measurement reference. The inertial units can not be used accurately. The simulation results show that calibration errors are mainly inducted by the factor errors and misalignment angles of inertial measuring unit.
