| Abstract: | Based on the theoretical and technical questions of adjustment for high-precision GPS baseline network, this paper discusses systematically the steps of GPS baseline network adjustment. Applications of baseline covariance, robust estimation, system parameter and reference model etc in the adjustment are analyzed emphatically. Finally, the adjustment software HPGPSADJ1.0 for baseline vectors is introduced, comparing with high-precise leveling, resolving precision of this software is analyzed. |
