The Recommendation considering that the geostationary-satellite orbit (GSO) is of unique usefulness to telecommunication services; that the interference imposes a limit on the number of satellites which may operate in the same frequency band in the same part of the orbit but the number will tend to increase as the degree of accuracy of station-keeping is improved; that the number of satellites using this orbit for operational purposes is likely to grow significantly in the next few years; that it is technically feasible to maintain satellite position to within fO.lO; although this standardmay not be achieved by some satellites designed before 1982; that the capacity of the GSO is only slightly impaired by moderate orbital inclinations but is greatly reduced when longitudinal positional drifts approach values comparable with the minimum permissible satellite spacing.
