Abstract

After USA removed the Selective Availability(SA), Global Positioning System(GPS) has monopolized tile world market and other countries have been depended on GPS, absolutely So the other countries, Russia, European Community(EC) and Japan, which apprehend to monopolize in technical and strategic parts, are developing the next generation GNSS including GLONASS Galileo and JRANS. And the countries are planning to provide the another GNSS. This research has focused on the next generation GNSS system based on GPS and Galileo system with developing a GNSS simulation software, named as GIMS2005, which generates and analyzes satellite constellation and measurements. Based on the software, a variety of simulation tests have been carried out to recognize limits of GPS-only system and potential benefits of integrated GPS/Galileo positioning In terms of satellite geometry strength and solution accuracy.
