Test Method of Inertial Instrument in LSINS

为了提高激光捷联惯导系统 (LSINS)的导航精度 ,需要测试系统中惯性器件的模型参数。本文设计了一种利用双轴带温控箱速率转台的参数测试方法 ,测得了系统在各种环境温度下的参数 ,通过建模补偿有效地减小了 L SINS的导航误差。实验结果表明本方法标定精度较高 ,适用于中等精度

To improve the navigation accuracy of laser strapdown inertial navigation system(LSINS), the model parameters of inertial instrument must be tested. In this paper a kind of parameter test method of using the double axes speed turntable with temperature control box is designed, and the parameters in various environment temperatures are calibrated. Because of temperature compensation the navigation error of LSINS is reduced effectively. As shown by the experiment results, this test method is more accurate and applicable to the medium accuracy LSINS.
