Interference between terrestrial and space stations, between space stations in the same system, and between
space stations not in the same system can follow many paths. These can be summarized as follows
ITU-R P.619-1-1992 history
2017ITU-R P.619-2017 Propagation data required for the evaluation of interference between stations in space and those on the surface of the Earth
1992ITU-R P.619-1-1992 PROPAGATION DATA REQUIRED FOR THE EVALUATION OF INTERFERENCE BETWEEN STATIONS IN SPACE AND THOSE ON THE SURFACE OF THE EARTH
ITU-R P.619-1-1992 PROPAGATION DATA REQUIRED FOR THE EVALUATION OF INTERFERENCE BETWEEN STATIONS IN SPACE AND THOSE ON THE SURFACE OF THE EARTH was changed to ITU-R P.619-2017 Propagation data required for the evaluation of interference between stations in space and those on the surface of the Earth.
