Abstract : This report presents the results obtained by using the short arc method to determine station coordinates for the purpose of calibrating the Doppler instrumentation used in determining geodetic parameters from satellite observations. The coordinates obtained were within three standard deviations of surveyed station coordinates in the majority of cases. Since this represented differences of five to ten meters, depending on the relative positions of the stations, when 24 arcs were combined, it is concluded that Doppler data processed by the short arc method give a reliable estimate of station positions.
