摘要

在不考虑罗差情况下

建立了捷联式磁航向测量系统的航向角误差模型

并结合无人机磁航向测量系统中框架式垂直陀螺仪的姿态测量特点

将其姿态误差源特征引入误差模型

全面分析了其航向角在不同飞行条件下的动态误差特性。对捷联式磁航向测量系统的航向角误差模型进行了仿真计算

并将仿真结果与飞行实验结果进行了比较分析。结果表明:捷联式磁航向测量系统的航向角误差动态特性符合无人机测量误差特点

能够为工程应用提供直接的理论依据。

Abstract

Error model of strapdown magnetic heading measurement system without considering magnetic deviation is built up

the dynamic error characteristics of magnetic heading under different flight condition for UAV is analyzed

combined with the attitude measurement characteristics of the frame type vertical gyro which is introduced into the error model. Error model is simulated

at the same time the simulation results and the experimental results are analyzed. The results show that the dynamic error character of the strapdown magnetic heading measurement system accords with the measurement error characteristics

and can provide theoretical basis for engineering application.
