| Abstract: | 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. |
| Keywords: | GPS baseline vector variance and covariance alternative estimation MINQUE method |
