The Development of a Global GPS Tracking System in Support of Space and Ground-Based GPS Programs

A GPS Global Tracking System for the 1990’s is called for to maintain accurate satellite ephemerides and terrestrial reference frames which support a broad class of geodetic, geophysical, oceanographic and engineering applications. The rationale for an international and civilian-operated GPS tracking system is quite evident in terms of its diverse applications and significant benefits to the scientific community. A description follows for a proposed organizational structure, physical configuration, operational characteristics and user interfaces, which together constitute a highly reliable internationally sponsored GPS Global Tracking System.
