光纤陀螺静态寻北算法的误差分析

摘要

以光纤陀螺静态寻北原理为基础,建立了3种常用寻北算法的误差模型,并定量计算算法中参数对寻北误差的影响.对3种模型的分析仿真结果表明,四位置寻北算法的寻北精度高,算法比较稳定,对纬度等寻北参数的敏感度小.%Based on the principle of static north finder scheme, error models of several north-finding algorithms were established, and the equations were accordingly deduced to calculate the error with the affection of every parameter in every north-finding algorithm. The result of verifying analysis shows that the four-position north-finding algorithm is less affected by the parameters, such as the latitude of the testing point, and has the higher precision and stability.
