车载卫星天线扫描与跟踪系统设计

内容简介：首先从车载天线接收系统总体设计方案进行阐述，给出了相应的系统框图，进而在论述中规划了车栽卫星天线接收主控系统的硬件设计模块.接着研究分析了此次硬件设计中使用到的接口：SPI、TWI、USART，完成了MEGA64主控模块的硬件设计，并给出系统板的原理图，最后，给出了车载卫星天线扫描跟踪算法设计.

Abstract：This paper starts with expounding total design scheme of vehicle-mounted satellite receive system. and give appropriate system block diagram. And then it charts out hardware design module in the vehicle-mounted satellite receive system. Moreover, this paper analyzes the interfaces that used in this hardware design ： SPI, TWI, USART, the hardware design of Mega64 control module including the schematic diagram is finished. At last, the design on vehicle-mounted satellite receive antenna scanning and tracking algorithm is given.
