The ITU Radiocommunication Assembly considering that some frequency bands are allocated for use by non-geostationary satellite orbit (non-GSO) satellite networks; that the number of operational and planned non-GSO satellite systems has risen significantly in the past ten years; that the interference experienced by such systems will become increasingly significant to other users sharing the frequency bands on a primary basis; that operators of non-GSO satellite networks and administrations may wish to measure certain non-GSO satellite radiofrequency (RF) characteristics; that the RF characteristics of non-GSO satellites are more difficult to measure than those of GSO satellites since the non-GSO satellites are moving with respect to the surface of the Earth.
