1. A method for maximizing auxiliary terrestrial component (ATC) and mobile satellite radio telephone system (MSS) capacity in a combination ATC/MSS system where the ATC coverage area overlaps the MSS coverage area comprising:
- assigning a first frequency (F1) to the auxiliary terrestrial component (ATC) component;
dynamically setting a filter on the satellite to suppress first frequency (F1) by switching in the filter based on a command transmitted from a ground location; and
allocating frequencies other than first frequency (F1) to the mobile satellite radio telephone system (MSS) component,wherein said dynamically setting a filter on the satellite to suppress first frequency (F1) comprises switching in a filter based on a predetermined time schedule.

Abstract
A system or method is disclosed which employs filters on a satellite whose bandwidth is varied by ground command to restrict interference experienced by a satellite as an auxiliary terrestrial component (ATC) system is increased to a multiplicity of cities and markets. Thus there is provided a novel method and system which optimizes overall MSS and ATC traffic.
