ITU-R F.1333-1 SPANISH-1999 Estimation of the Actual Elevation Angle from a Station in the Fixed Service Towards a Space Station Taking into Account Atmospheric Refraction
In some cases of sharing studies, the elevation angle of a space station (geostationary or non-geostationary), as seen from a fixed service station, is known only in free-space propagation conditions in vacuum. In such cases, it is necessary to estimate the actual elevation angle taking account of atmospheric refraction. This annex gives a calculation method for such a need.
