Research Of GPS Kinetic Positioning Based On Bernese Software

This paper, based on the study of GPS kinetic positioning technology and BGPS static data processing software, studied a method of resolving ambiguity, and primarily came into being a GPS kinetic data processing software.In the "close shot target three-dimension measure technology" from country 863 project, the main function of GPS conceiver is to determine the trace of vehicle-carried movement, and provide the geography coordinate frame of scanner. Nowadays, there are some high precision processing kinetic data softwares in the world. As a result of the limit of copyright, they don't benefit the commerce of three-dimension measure system.BGPS opens its codes, all of the programs and subroutines are modeled. And has a good interface, there are not constants in the modules, users may change them by the needs. And has good function which estates parameters and processes some kind of data. So it possesses significant study and extending value. GrafNav is a commercial software of GPS data processing. Its data processing has higher precision in terms of special method. It is guide meaning for both software design and methods, to know its data program models and ways. At the same time, its data results may be regarded as the standard of the program, which was written by the author.After grasping VISUAL FORTRAN90 and BGPS, the author studied the data demand, the paths and contents of temporary files, the transfer of observation files and relative contents, the update of precision orbit in the processing. According to the character and demand of vehicle-carried kinetic positioning, the author studied a fairly ideal method of calculating ambiguity. Under the one epoch, use P2 and the WL-corabination L1/L2 to realize single epoch solution ambiguity, which is used to calculate the coordinates of sample points in the coordinate frame of WGS-84. Then transfer the values in local coordinates. All that was programmed.After the programs above were debugged with simulate data, a kinetic programming data software was elementary succeeded.
