A Simple Method of Mounting Bracket Self-Calibrationfor Civil Aircraft IRS

为提高机载惯性基准系统托架安装误差的标定效率，降低过程复杂度，提出了一种简便的托架自标定方法。对托架标定的原理、总体架构及标定流程进行了设计，并在此基础上给出了机体航向测量误差的评估算法。仿真及实际验证结果表明，本方法简单有效，可在具备同类惯性基准系统架构的各类飞机中推广。

To improve the calibration efficiency of airborne IRS bracket mounting error and to reduce the complexity of process, a simple method of bracket self-calibration is present. The principle of bracket calibration, overall architecture and calibration process are designed, and based on which an estimating algorithm of airplane heading measurement error is proposed. The simulation and actual verification results show that this method is simple and can be promoted in the airplane which has similar IRS architecture.
