| 摘 要： | 通过对多个全动卫星地面站天线塔不均匀沉降的长期连续测量，得出了其不均匀沉降的大小及变化趋势。分析了不均匀沉降对天线测角精度的影响，研究了不均匀沉降的补偿方法。中小型天线一般自身设置有机械调平装置，可进行一定量的调整补偿。更为普遍的补偿方法是用数学模型来修正不均匀沉降带来的测量误差，大天线和中小天线都适用。工程中这些方法都已应用，效果良好，对提高天线塔建设效费比有重要意义。

| Abstract: | The uneven settlement degree and change trend is obtained through long-term continuously measuring the uneven settlement of satellite earth station antenna tower.The influence of uneven settlement on the antenna measurement accuracy is analyzed and compensation method for the uneven settlement is discussed.For medium-sized and small antennas,a certain amount of compensation settings can be performed by the leveling device of antenna. More general method is to use mathematical model to correct the angle error caused by uneven settlement of antenna tower and it is useful for large,medium-sized and small antennas.The methods have been applied in engineering and performed well,which are important for improving the antenna tower construction cost-effectiveness. |
