NAVSAT is a civil complement to the satellite navigation systems NAVSTAR GPS (US Global Positioning System) and GLONASS (Russian GPS). Using these systems as a base with proven performance characteristics, the build up of a kernel system for a future civil satellite navigation system is intended. A proposal to solve the integrity problem of GPS and GLONASS for civil aviation requirements and to enhance the availability, coverage and accuracy is considered. These tasks will be attained by aid of small navigation payloads flown on suitable host satellites, using a navigation signal with a structure that is compatible to GPS and GLONASS, an appropriate ground segment for navigation signal uplink, satellite position determination, time transfer, communication and set of health monitoring units is the responsibility of national aviation authorities. In the future, this basic constellation may be augmented by additional geostationary and Tundra type satellites to achieve a global service.
