<br>
Hello all,<br>
<br>
<br>
I?ve been testing the use of RTKLIB/RTKPOST (all patches applied) for<br>
Static RTK, with or without GLONASS (I?m receiving signals from 6 to 8 GLO<br>
satellites). The hardware I?m using is exactly the same, both for rover and<span class=""><br>
for reference. The baseline is 55 meters long.<br>
<br>
<br></span>
I?m collecting my observations at 20 Hz using 10-minute span RINEX files.<br>
For carrier frequencies I?ve been using L1+L2 and ?fix-and-hold?<br>
ambiguities for GPS. After inspecting the positioning results I?ve got so<br>
far I?ve noticed that:<br>
<br>
<br>
1. For GLO ambiguities, the same results are obtained either selecting ?ON?<br>
or selecting ?AUTO?.<span class=""><br>
<br>
2. Exactly the same results (up to the forth decimal!) are obtained<br>
regardless using GPS+GLONASS or GPS-only data.<br>
<br>
<br>
The behavior described in 1. can be easily explained by recalling that the<br></span>
GNSS hardware I?m using is the same, both for reference and for rover.<br>
<br>
<br>
However the behavior described in 2. keeps puzzling me and that?s the<br>
reason why I?m asking for your help.<span class=""><br>
<br>
<br>
One small data file is available at<br>

<br></span>
containing RINEX sample data and the positioning results I?ve got when<span class=""><br>
using that RINEX data sample. Hope someone can help me.<br>
<br>
<br>
Best regards<br>
<br>
