Scheme of positioning constellation would greatly influence the positioning performance. In this paper, a GEO/HEO hybrid constellation with 3 HEO satellites deployed in 3 orbits and 3 GEO satellites for regional positioning is presented. Firstly, elements for 3 GEO and 3 HEO are optimized from regional visibility for the selected region of interest. Secondly, positioning performance is provided through GDOP(geometric dilution of precision) and PDOP(positional dilution of precision). Simulation results show that similar accuracy with GPS can be gained by this constellation.
