Conceptually, GPS geodetic surveying is a descendant of hyperbolic radio positioning systems such as LORAN and Omega, of the 'very long baseline' interferometry technique of radio astronomy, and of satellite Doppler tracking. Satellite Doppler positi

Millimeter-accuracy satellite navigation, defined as the determination of instantaneous position coordinates of a point on a moving platform (land/sea/air/space vehicle) with respect to a reference frame defined by points fixed on the ground, with mi

Three distinct tasks were undertaken to advance the application of space techniques to the measurement of geodetic parameters: error analyses were performed to estimate the accuracy with which the locations of satellite tracking stations and the moti

The positions of extragalactic radio sources have been determined by very-long-baseline interferometry with uncertainties smaller than 0″.1, and fundamental limits on the accuracy of VLBI astrometry have not yet been reached. Technical improvements

Important advances were made between 1971 and 1974 in the development of very long base line interferometry (VLBI) techniques for precision geodesy, including repeated determinations of the length of a transcontinental base line within 5 parts in 108
