 针对光电搜索侦察系统报告搜索到的空中目标当前方位、俯仰位置给后端武器打击系统的需要，在光电搜索系统与后端武器打击系统之间建立大地坐标系是解决此类问题的较好方法， 以便后端武器打击系统指向搜索到的空中目标。介绍了数字电子罗盘HMR3000的接口特性，给出了HMR3000的控制编程以及与DSP的接口电路，同时也给出了HMR3000电子罗盘获取光电搜索系统平台方位轴系相对地理正北的获取流程和编程实现方法以及DSP端相关程序。结果表明系统坐标系建立精度达到±0.5°，重复精度达到±0.1°，且能稳定运行。
Abstract:
 Aiming at the demand against report angle of azimuth and pitch of current target in the air by photoeletricity search information system detected to rear-end weapon PLSS，establishing of coordinate system of earth was preferable method to resolve openstream questions in photoeletricity search information system and rear-end weapon PLSS for rear-end weapon PLSS to point to target in the air by system detected. Interface characteristic of HMR3000 e-compass was introduced in the paper， control programming of HMR3000 and interface circuit between DSP and HMR3000 were given.Acquisition process of photoeletricity search information system platform azimuth axis relative to earth due north by HMR3000 e-compass obtained and realization method in programming and related program in dsp-end were given. Conclusions indicate precision of established coordinate system is in zero point five degree，repetition precision is in zero point one degree，and can steadily operate.
