Hello, I am trying to calculate the precise positioning of a receiver using the observation (*.o), navigation (*.n), and precise positioning (*.sp3) files with the command-line program rnx2rtkp from RTKLIB. However, it does not appear that the *.sp3 files have any effect toward the navigation solution. For example:
duly@remote2:~/GEONET/test$ rnx2rtkp 02130700.11o 02130700.11n -p 0 -o 02130700.pos duly@remote2:~/GEONET/test$ rnx2rtkp 02130700.11o 02130700.11n -p 0 -o 02130700-fine.pos *.sp3 duly@remote2:~/GEONET/test$ diff 02130700.pos 02130700-fine.pos 3a4,9 > % inp file : igr16264.sp3 > % inp file : igr16265.sp3 > % inp file : igu16264_00.sp3 > % inp file : igu16264_06.sp3 > % inp file : igu16265_00.sp3 > % inp file : igu16265_06.sp3 As shown, the only difference between the two processing techniques is that the program merely recognizes the *.sp3 files-- it does not appear to use them in the navigation solution. Does anyone have any idea why the sp3 files are not used by the program? Thanks, Tim -- ------------------------------------------------- Timothy M.
