Navsat - A global satellite based navigation system
Abstract
The Navsat 12-satellite highly eccentric orbit - plus - six-satellite geosynchronous orbit system constellation currently accepted as the baseline design is noted to be able to significantly reduce operating costs while furnishing navigation performance comparable or superior to that of GPS. The constellation is also noted to facilitate the implementation of the planned integrated navigation/communications/search-and-rescue service. With only two geosynchronous navigation satellites and three highly eccentric orbit satellites, full operational capability is achievable in the areas where the service is most needed.
