<div>Hi Robin<br>

As the old saying goes.... it depends.<br>
<br>
</div>
Some solutions are designed for static positioning (ie a
person standing holding a pole still for n seconds while
the position converges) and some are for dynamic
positioning (ie your walnut harvester bumping along at a
metre or so per second).<br>
<br>
</div>
Some GNSS information (eg. velocity/heading) are only
reliable at more than a certain speed - maybe 1 or 2
metres/sec.<br>
<br>
</div>
A lot will depend on antenna quality and various other
factors.<br>
<br>
</div>
There are heaps of satellites up now, so good
multi-constellation receivers are giving very good results these
days.<br>
