<div class="moz-cite-prefix">Hi,<br>
You will "always get better" positioning off a commercial GPS than
a cellphone based one.<br>
I put that in inverted commas because times change, and depending
on your terrain (city buildings, trees, mountains) and accuracy
requirements, "better" might not be needed for your job.<br>
<br>
My suggestion is look at the error ellipse of your device,and
decide if it is good enough. If you are positioning doors that are
next to each other (like town houses), you need to make sure that
the GPS value recorded is close enough to your door, than the one
just next to it (like 1.5m away).<br>
<br>
I used a Garmin 60CSX connected to a QGIS laptop via Franson
GPSgate and the solution worked really well.<br>
The GPS unit must be capable of streaming NMEA data, so choose
carefully.<br>
<br>
So, with more info about what you want to do, you might get more
responses.<br>
