WRC 2003 Agenda Item Details

Agenda Item: [Resolution 137]
Resolution(s): Resolution 137 (COM 5-7)
Description of work: Further studies of the sharing conditions between GSO networks and non-GSO systems in the FSS to 1) develop methodologies to assess the operational and additional operational EPFD levels that may used to compare against the relevant limits, 2) develop data formats that can be used to describe the non-GSO systems in sufficient detail for assessments of the operational and additional operational limits, 3) develop methodologies for generation of continuous EPFD vs % time curves for other GSO ES antenna diameters than those in the limit tables, 4) develop methodologies for generation of continuous EPFD vs % time curves for GSO satellite beamwidths other than those in the limit tables, 5) study the sharing criteria that may be applied during coordination between non-GSO FSS systems
Lead Study Group:: SG 4

How Visualyse products can help: Visualyse can model GSO and non-GSO FSS systems in detail and can can be used to calculate the EPFD the non-GSO system would generate taking into account accurate modelling assumptions that may then be compared against the additional operational EPFD limits. Visualyse can also be used to calculate interference between non-GSO systems, taking into account constellation avoidance tracking strategies and potentially multiple constellations.
