THE ESTIMATION OF VARIANCE AND COVARIANCE COMPONENTS FOR GPS BASELINE NETWORK BY MINQUE METHOD

This paper studies the estimation of variance and covariance components for GPS baseline network by MINQUE method. The fundamental rule for selecting variance-covariance model has been presented, and the alternative algorithm which simultaneouly estimates fixed variance components and scalled variance components of the distance, azimuth and geodetic height difference for a GPS baseline vector has been developed.
