<p>Hello All,</p>
<p>I recently acquired a Trimble GeoXT 2005 Series and am puzzled by
the results it produces:</p>
<ol>
<li>Compared to a variety of "known" points, it consistently
records positions that appear to be in error by 1.2 - 1.5 m NW
from the known point. <br>
</li>
<li>Points are collected and then mapped in QGIS as NAD83, UTM
Zone 10 N. <br>
</li>
<li>The known points include property survey pins, Government
control survey monuments, Total Station survey points derived
from the above, other GPS results (Trimble ProXRS) and
identifiable points on orthophotos. <br>
</li>
<li>I'm using SBAS correction in the GeoXT.</li>
</ol>
<p>It appears to be adding a consistent offset to the GPS result
although no offset has been set in TerraSync.<br>
</p>
<p>Many thanks for any thoughts on this situation . . . . .<br>
