Abstract

In Satellite Communication Systems, dynamic resource management requires the calculation of beam to beam distances or interference/isolation cost. Such resource management schemes are exem- plified by the IRIDIUM Space Vehicle Real-Time (SVRT) and Dynamic Channel Management System (DCMS). On-line calculation of the distances is expensive, whether using Euclidean distance or great circle distance, since it involves earth geome- try and coordinate transforms.
