The ITU Radiocommunication Assembly considering a)that the density of satellites in the geostationary-satellite orbit (GSO) is governed by the interference deemed to be acceptable to each network;b)that the computation of interference is currently performed by deterministic methods which, in general, assume worst-case conditions in order to avoid unacceptable levels in all cases; c) that this approach sometimes leads to unduly conservative estimates, resulting in inefficient use of orbit capacity.
