摘要
为实现对卫星信号的快速搜索和高精度指向,提出一种利用三维电子罗盘对卫星实现自动定位的系统.通过对步进跟踪过程的分析,结合系统模块化设计思路,分析和设计了自动定位系统的硬件模块和软件中的控制算法.为提高整个系统的抗干扰能力和跟踪精度,采用空间坐标式跟踪来代替十字跟踪,从而快速准确地进行卫星定位.
In order to achieve the satellite signals quick search and precision pointing,utilizing three-dimensional electronic compass to achieve automatic positioning satellite was presented in this paper.Through analyzing stepping tracking process and combine the system with modular design ideas,the hardware module of automatic positioning system and control algorithm of software were analyzed and designed.In order to improve anti-jamming capability and tracking accuracy of the entire system,space coordinate tracking was used instead of cross track,which can realized satellite positioning fast and accurately.
