卫星跟踪系统动中通

The Satellite communication system-"Connection in moving"

在研究卫星通讯地面站的动中通设备时,要求天线系统在车载机上能很好地跟踪指定的卫星。系统应具有距离、速度、加速度的跟踪能力。本自动跟踪系统采用无刷直流电机来作为驱动动力。采用EDA技术设计电路。以CPLD芯片EPM7128SLC84-3来作为设计的目标器件。在MAXPLUSII上进行软件设计、编译、仿真和下载。

At studying the ＂Connection in moving＂ equipments,of the satellite communication earth station,we request that the antenna system carried on the car can follow the appointed satellite very well. So it requests this system have following ability of the distance, speed, acceleration.The automatic following system of automatic control system adopts the three winding and brushless PMDC.This system adopts EDA technique to carry out the software design,compiler, simulat and program in the MaxPlusⅡ. We use the EPM7128SLC84-3 of CPLD to be the target device.
