| Description | All users of the NAVSTAR Global Positioning System (GPS) located within a rather large geographical area are currently required to perform a number of identical, common operations in order to accomplish a navigation "fix" (additional "location dependent" operations are also required). Under the REFSAT concept, the common operations are performed at a central location and results broadcast via a geostationary reference satellite (REFSAT). This concept allows a considerable reduction in the cost and complexity of individual civil user terminals. The hardware design of a REFSAT/GPS receiver terminal and the REFSAT transmitter simulator is described. Since six of the Phase 1 NAVSTAR GPS satellites are now operational a demonstration test plan utilizing the one-to-two hour per day viewing window is also described. Equipment check-out preliminary test results are presented. |
