WT-1卫星天线自动控制器

本设备是一种用于控制WT-1卫星接收天线自动跟踪信号的先进装置。它主要由单板计算机,扩充I/O接口,16通道8bitA/D转换器,两个天线角度信号变换器,CRT显示器和显示图形控制板以及功能较强的应用软件等构成。 主要功能有自动定时,自动预置天线到初始信号接收位置。系统可控制天线捕获和自动跟踪卫星信号。在工作中,CRT能够实时显示各种参数和图形,例如时间、天线位置数值以及卫星飞行轨迹、伴有地形图的接收大圆形等。

An auto-controller for WT-1 satellite antenna

This device is an advanced equipment used to control WT-1 receiving antenna to track satellite signals automatically.Its main parts consist of:a single-board microcomputer containing an expansion I/o interface, an 8-Bit A/D converter with 16 channels, a CRT display in addition to a graphic-control module, two angle transfer parts of the antenna, as well as some application programmes with versatile function.The functions are as follows:The equipment can carry out time-counting, and move the antenna to the predetermined primary position to pick up the signals. The system can control the antenna to track satellite signals automatically. CRT displays various parameters and graphics in real-time, such as current time, present position of the antenna,flying track of the nadirs of satellites, the pan disk-graphic of the receiving scope of the ground station along with geographic landimarks.
