[FOSS-GPS] Using sp3 files with rnx2rtkp from RTKLIB-- no effect on solution

[Timothy Duly]

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 at remote2:~/GEONET/test$ rnx2rtkp 02130700.11o 02130700.11n -p 0 -o
02130700.pos
duly at remote2:~/GEONET/test$ rnx2rtkp 02130700.11o 02130700.11n -p 0 -o
02130700-fine.pos *.sp3
duly at 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
