- ARNS protection and planning implications The ITU-R Recommendations quoted above have identified and calculated the sharing criteria necessary for the protection of all of the present ARNS systems known to use the band. These indicate, among other criteria, the need for coordination distances of between 310 km (landing and airborne radar measurement systems) and 600 km for general purpose airborne radar, referenced to the areas of operation. Coordination with the location of ground Earth stations prior to implementation is necessary to assess the potential for interference. These limitations and those of the power flux-density in the space-to-Earth direction create difficulties in terms of the siting of the FSS Earth station. Concern is expressed on the practicalities to maintain an exclusion zone around FSS stations for aircraft equipped with these systems.
