| 摘 要： | 为实现自动快速对星需求，电子罗盘已成为车载天线伺服系统的重要组成部分。但受到安装位置和地域环境磁场的影响，电子罗盘的测量数据会发生某种偏差，从而造成对星目标计算误差，在一定程度上制约了天线快速对星性能。文章以Honeywell公司生产的HMR3000为例，对电子罗盘定向应用进行深入研究，并给出主要标定方法的实现过程。该文对于电子罗盘在工程应用实践有着重要的参考价值。

| Abstract: | The electronic compass has become an inportant part of the antenna servo system on mobile vehicles for pointing to a particular satellite automatically and quickly. But the compass mounting location and additional magnetic fields generated by the host will cause its data deviation, take error in azimuth computing for the satellite, and limit antenna pointing to the satellite quickly in some extent. Based on HMR3000 produced by Honeywell compary, the paper describes the application of the electronic compass in the antenna servo system of Mobile vehicles and the several calibrating methods in detail, which may provide significant referrence in system implementation. |
