| Abstract: | With widespread application of GPS techniques in surveying, several high precision GPS control networks have been established in China. It is an urgent problem to process the observational GPS data fastidiously and to establish the processing software. In the paper, the principle for adjustment is discussed systematically using virtual baseline observations. The applications of robust estimation with bifactor equivalent, estimation of system parameters and variance component estimation etc, in GPS net adjustment, are analyzed. Finally, the adjustment software GPSADJ for baseline vector is briefly introduced. |
