Atskirų parametrų įtaka apdorojant GPS matavimų rezultatus programiniu paketu GPPS

Abstract

The Lithuanian first order GPS network was established in the 1993. Observations were performed with 4 two frequency Ashtech P-12 GPS receivers. The influences of individual parameters on the adjustment results are described. Totally 68 cases for o-files analysis were selected. They were created as a combination of separate parameters. Different combinations were created by changing values of 8 parameters. The analysis of each parameter influence is described in the separate section. Conclusions and some baselines accuracy charts are presented in the end of the paper.
