A Consistent Geodetic Reference System for GPS (Global Positioning System).

Abstract

Independent evaluation of the new GPS Operational Control System (OCS) is an Air Force objective. For this purpose, continuous counted, carrier tracked phase data of the six Navstar satellites from the Air Force Geophysics Laboratory's (AFGL) MIT receivers was requested. These data are combined with conventional GPS pseudo-range data to estimate the Navstar orbits and the GPS Intermediate Control System (ICS) station locations. It was discovered that the ICS station net was inconsistent with the AFGL/MIT receiver locations. The difference between the two reference systems is about 10 meters in longitude.
