On the Observations and Computations Carried out in the Second European Doppler Observation Campaign (EDOC-2) for Position Determinations at 37 Satellite Tracking Stations

摘要

The motivation for EDOC-2, field operations, data pre-processing and computational methods are described. All solutions computed by the different computing centers are analyzed and presented as differences with respect to the finally adopted solution. The results include computations, using both broadcast and precise ephemerides. The comparison with European Date 1950 shows up obvious regional deficiencies in the terrestrial network. Geodetic coordinate sheets of the different stations are presented.
