低精度传感器在动中通天线姿态控制中的设计应用

摘要

In order tofi tting future marking require, we use the combination, which includes low precision sensor and stepping motor, to replace the common combination including inertial navigation unit and high precision sensor in the Seaborne Satellite Communication when the former combination can meet the required precision of antenna attitude control by using later combination meanwhile extremely reducing the whole components cost.%本文介绍了在船载"动中通"天线中利用低精度传感器和步进电机来替代常见的惯导单元或者高精度传感器,在达到不亚于使用后者的天线姿态控制的精度要求同时,极大地减小元件成本,更适应未来的市场需求.
