摘要/Abstract

摘要： 根据地面站址位置与静止卫星的定点位置所给出的站仰角和方位角公式,分析了纬度以及经度差的变化状况,绘出了仰角和方位角基值的诺谟图。本诺谟图对南、北半球地面站均适用。与计算值相比可知,诺谟图所得数据能保证0.1°或更高的精度。

Abstract: Based upon the formulae of elevation and azimuth angles forGround-station with its given altitude and the difference between its longi-tude and satellite longitude,the variation behaviors of altitude and of diffe-rence between longitudes have beed analyzed,and the Nomograms for eleva-tion and basic-value of azimuth are produced.These Nomograms may be uti-lized both in North-and in South-hemispheres,As compared with the calcu-lated values,Nomogram data ensure an accuracy of 0,1°or even higher.
