摘要
基于舰载卫星天线三维伺服跟踪系统,通过二维电机驱动机制控制天线方位角、俯仰角和极化角。并以轮船卫星天线陀螺传感器和电子罗盘所得数据,推算验证接收器指向坐标。然后得其天线指向相对于初始坐标的坐标值转换公式。再用电机伺服驱动系统控制天线转动,调整其重新指向卫星接收信号。Matlab仿真证明该方法可行。
Based on the three-dimensional servo tracking system of carrier-based satellite antenna, the azimuth angle, elevation angle, and polarization angle of antenna were controlled through two-dimensional motor driver mechanism. The data, which acquired from ship satellite antenna top sensor and electronic box and needle, was used to calculate and validate the receiver point coordinates; then, the coordinates conversion formula between the antenna point and the origin coordinates was acquired. The motor servo drive system was used to control antenna turning, adjust the antenna to point at satellite again and receive signal. The Matlab simulation showed that this algorithm was practical.
