Abstract :
Proposed allocations by the ITU in the Ku and Ka frequency bands for facilitating induction of non-GSO (non-geostationary orbit) systems using satellite constellations in low Earth orbit have raised a host of contentious issues. The problem of sharing of the radio frequency spectrum by non-GSO systems with the existing terrestrial and GSO satellite systems is complex. Any decision without a complete study is like to lead to the imposition of serious constraints and inequitable allocations. Sharing studies are in progress under the ITU Forum. A Joint Task Group set up on the directions of WRC-97 has concluded its examination of various issues. Due to shortage of time and resources the issues could not be resolved and need to be examined further for ensuring equitable sharing of the radio frequency spectrum. The unresolved issues are discussed.
