Estimation of Variance and Covariance Components for GPS Baseline Network by MINOUE Method

This paper studies the eatimation of variance and covariance components for GPS baseline network by MINQUE method. The fundamental rule to select variance—covariance model has been presented, and the alternative algorithm which simulaneously estimate fixed variance components and scalled variance components of the distance, azimuth and geodetic height difference for a GPS baseline vector has been developed.
