Geodetic positioning using a Global Positioning System of satellites
Abstract
It is pointed out that the Global Positioning System (GPS) is a passive all-weather navigation satellite system proposed for operation after 1985. The system uses the concept of passive satellite navigation based on highly accurate atomic frequency standards to enable the navigator to determine his three-dimensional position, velocity, and time instantaneously on a continuous worldwide basis. Attention is given to the results of an analysis of geodetic positioning obtained from both GPS range and integrated Doppler observations. One of the basic aims of geodesy is the precise determination of the coordinates of points of interest in an adopted earth-fixed frame of reference. The presented results demonstrate that GPS range and integrated Doppler observations will provide sufficient accuracy for estimation of geodetic coordinates.
