【摘要】 该装置以ARM9为核心,采用Windows CE多线程编程技术,分别采集GPS和电子罗盘等传感器件数据,加以综合计算,得到卫星通信天线对星的理论值与实际值,调整天线指向使实际值与理论值一致,即可完成对星。使用该装置能够明显缩短对星时间,平均对星时间由原来不可预知,缩短到2 min以内,显著提高了通信效能。该装置在天线方位角的磁偏角修正方面具有先进性。更多还原

【Abstract】 This device based on ARM9 collects the data from GPS and compass,then the theoretic value and the real value can obtain by computing the data.The antenna can be rotated to make the real value equal to the theoretic value,then the antenna is aimed at the satellite accurately.Using this device can reduce the time of aim the satellite,the average time for aim the satellite can be reduced from the unpredictable period to 2 minutes,then the efficiency of communication is increased markedly.The device is advanced on the azimuthal angle revised by the declination.更多还原
