High Accuracy Global Positioning System Orbit Determination: Progress and Prospectsnstellation is presently in orbit; however, most of these satellites are of a developmental Block I design and eventually will be replaced by the operational Block II satellites. The GPS constellation is designed to evenly distribute the satellites with circular orbits in three different planes at a

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

High Precision GPS Positioning by Fiducial Techniquesger networks incorporating baselines of up to several thousand kilometres, an error of 1 ppm corresponds to a relative error of the order of 1 metre. To obtain centimetric relative positioning accuracies in such cases, an improvement of one or two orders of magnitude is required. This may be achieve

Populists and Progressives Speak Out,From a practical point of view, it is useful to develop a preprocessing software, which could enables one to evaluate all data received immediately after an observational session. The approach presented here make it possible to estimate if observations at a site should be repeated.
