Comparative Analysis Of Gamit And Bernese In The GPS Network In Data Processing

With the development of GPS technology, which has been widely applied in various areas ofsociety. Currently on how to achieve high-precision positioning using GPS orbit is animportant part of the GPS research, and has achieved fruitful results. Although there havebeen many static GPS data processing software, but for some high-precision engineeringneeds,such as the National Network of Class A measured, long baseline, etc., have weactually reach the precision engineering, so we must introduce foreign the GAMIT andBernese precision software.Paper from the structure and characteristics of GAMIT and Bernese software, two softwarestructure and function in the choice of the reference frame, the phase center model is selected,a priori coordinates of the selected ambiguity resolution methods and other aspects of acomparative analysis to Both software research principles and methods to achieve precisepositioning orbit determination. IGS stations through the data were analyzed, we need toprovide reference for practical engineering. Finally, the two-level software Chongqing Adata processing network, and comparing the results, in order to achieve high-precisionpositioning. Secondly, both the principles and methods of software research for the study ofthe high-precision positioning software provides a theoretical basis.
