摘要

提出了一种利用电子罗盘实现陀螺经纬仪粗寻北自动化方案。通过分析电子罗盘的原理和影响其精度的因素

对电子罗盘进行了校准。设计了基于DSP的控制电路

根据电子罗盘的输出驱动系统指向粗北方向。实验结果表明:电子罗盘粗寻北系统的精度在±30′以内

完全满足使用要求

粗寻北时间由10

5min减少到1

min。

Abstract

In order to realize automatization of gyroscope north finder

a coarse north-finding method through electronic compass is presented.The principle and the accuracy influence factors of the electronic compass are analyzed.And the electronic compass is calibrated by different method.The control circuit based on DSP is designed.The system is driven to the coarse north direction by the output of the electronic compass.Experiment result shows the precision with ±30′can reach the requirement and time of coarse north-finding is reduced from 10

5 min to 1

min.
