<div dir="ltr">Hello,<div><br></div><div>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:</div>
<div><br></div><div><pre style="padding:0px;margin-top:0px;margin-bottom:0px;overflow:auto;font-family:'Courier New',Courier,monospace;line-height:1.3;color:rgb(0,0,0);font-size:13px">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

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.</div><div><br></div><div>Does anyone have any idea why the sp3 files are not used by the program?</div>
