摘　　要：提出了一种在不带有反转平台的精密离心机上标定陀螺加速度计误差模型系数的两位置测试方法。在对陀螺加速度计离心机测试环境分析研究的基础上,指出了在不带有反转平台离心机上测试时,地球自转角速度对陀螺加速度计的输出产生周期性误差,影响了测试精度。所提出的测试方案和辨识方法解决了地球自转角速度对陀螺加速度计的输出造成周期性误差这一重要问题。阐述了所提方案的测试原理,并提出分离和精确标定陀螺加速度计误差模型系数的数据处理方法。A two-position test method for calibrating error model coefficients of PIGA（pendulous integrating gyro accelerometer） using precision centrifuge without counter-rotating platform is presented.Based on the analysis and research of the environment of PIGA test on centrifuge,that is pointed out the earth rotation angular velocity brings periodic error to the test output of PIGA on centrifuge without counter-rotating platform,which is harmful to test accuracy.The test scheme and identification method were given which solved the problem of periodic error caused by the earth rotation angular velocity.Its testing principle was expounded,and a data processing method for separating and accurately calibrating error model coefficients were presented.
