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.
