                         concerning to the design of a Regional Positioning System - RPS 
                         satellite constellation to cover the Brazilian territory. The 
                         paper presents an overview of constellation design possibilities 
                         for a hypothetical Brazilian Regional Positioning System. Since 
                         Brazil is located near the equator plane, the idea is to think 
                         about a RPS satellite constellation that takes advantage of this 
                         fact in order to design a cost effective regional system that aims 
                         at covering primarily only the Brazilian territory. In this sense, 
                         three satellite constellation types were considered. The first one 
                         is composed by Low Earth Orbit - LEO satellites with low to 
                         moderate orbital plane inclination angles. The second one is based 
                         on Medium Earth Orbit - MEO satellites placed in the equator plane 
                         or near to it, and the third one is based only on geosynchronous 
                         satellites. A preliminary optimization process was run in order to 
                         obtain an initial guess of a good design. The obtained design 
                         constellations are presented and discussed.",
