Although the U.S. Department of Defense is developing the NAVSTAR/Global Positioning System (GPS) for its military positioning and navigation requirements, there are obvious civilian benefits to be gained from exploiting this global satellite system. No present navigation system offers the continuous worldwide accuracy in time and position which GPS will deliver. Even now, with only four prototype satellites in operation, GPS users have demonstrated that the accuracy of the system has exceeded design goals. Future applications will include geodynamics, the unification of geodetic datums, surveying, mapping, navigation, hydrography, offshore resource exploration and development, and marine and air traffic management.
