Abstract

The GEOSAT software for satellite geodetic and geodynamics applications has lately been extended to Very Long Baseline Interferometry (VLBI) applications. Geodetic VLBI data have been analyzed using this software and station coordinates and velocities, source coordinates, and earth orientation parameters have been derived in a global mode using data from the Extended Research and Development Experiment (ERDE) and the Research and Development series (R&D) within the NASA's CDP.

It is demonstrated using the ERDE data, that the program is capable of calculating station coordinates with an accuracy of a few mm in the local horizontal plane and about 7 mm in the vertical direction. Analysis of the R&D dataset yields errors 2 to 3 times higher in all directions.
