惯测组合快速高精度标定方法研究

Research on the High Accuracy Rapid Test Method of IMU

研究了基于机械转子陀螺的捷联惯性测量组合位置标定的一种不对北免调平测试新方法,提出了利用位置转换进行速率标定的快速测试方法,大大缩短了测试时间。同时,采用脉冲计时取代传统的脉冲计数,显著提高了参数标定的精度。采用该方法实现了惯性测量组合的高精度快速测试。

This article researches a new method of mechanical gyro strap-down inertial measurement unit position calibrating which is not-aiming-north-and-not-leveling.It brings forward the rapid test method that calibrating the rate by using position switch.Using pulse timing instead of traditional pulse counting,it prominently improves the accuracy of parameter calibration and accomplishes the high accuracy rapid test of inertial measurement unit.
