Porovnání přesnosti výstupu post-processingu GPS měření z různých software

Abstract

Thesis deals with the quality evaluation of post-processed GPS measurements from different sofwares and techniques of processing. Comparison is based on own proposed and realized GPS measurements. During the proposal of suitable measurement campaigns, various influences and effects were taken into account. Measurements are divided into static and kinematic solutions. Processing of data was realized by two different methods. The first is differential GPS method (DGPS), which was supported by all used PP softwares. The second one is technique called Precise Point Positioning (PPP) which expands standard stand-alone technique. PPP solution was available only in one of selected softwares. For the quality evaluation differences between processed coordinates and precise reference coordinates were used. There were no essential differences in the outputs of DGPS method. PPP technique in some cases can compete to DGPS method.
