Pulse width modulation implemented in position servo system of mobile antenna;
移动天线位置伺服系统的正弦波脉宽调制方法
The movable spot-beam antenna of satellite is used widely for its simple structural and high precision.
卫星点波束可移动天线以其结构简单,高精度等优点得到广泛应用,天线地面应用软件便是对其进行可视化监控而设计的。
Movable antenna with spot beam is a key component in the pinpointing and tracking of the ground object through a satellite,is uses a dual-axis orienting mechanism to realize the moving and pointing in the yaw and pitch channels.
可移点波束天线是卫星系统对目标定位和跟踪的重要组成部件,该天线依靠双轴定位机构来实现在俯仰和方位两个方向上精确运动和定位。
