<p>Hi Ivan -</p>
<p>I've experienced similar problems with other GIS applications and
platforms. In some of these cases, the problem was caused by the
GPS delivering "to many" positions to the application. Instead of
generating (perhaps) 1 fix/sec the GPS generated 10 fixes/sec and
overwhelmed the input buffer in the application. <br>
</p>
<p>The visible symptoms is that the GPS position trails behind the
actual position. If you stop walking, the the GPS position
eventually catches up to the actual position.<br>
</p>
<p>You might try the slow the number of fixes/sec (if it's
possible). This is just a guess. I have no experience at all with
the Trimble TDC600 at all. <br>

about 100 m from that place and the position of the point was
