<p>Hi,</p>
<p>I just jump in this thread to say I'm really impressed with
Ardusimple. I have a RTK Handheld Surveyor Kit [1] for +- 400 €
and it works really well.</p>
<p>I use the national NTRIP service and I have consistently
precisions around 10 cm with just one receiver. <br>
</p>
<p>I use a free Android application called SW Maps [2]. My survey
points, tracks and photos are collect in a geopackage that I can
read in QGIS. I use it mostly to collect ground control points for
my drone flights.<br>
</p>
<p>Regards,</p>
<p>Jorge Gustavo<br>

I have an earlier Emlid Reach (not RS or RS2), which has L1 only, and I
never got it to work well.
Also look at the Ardusimple unit -- but it's more a parts kit than a
system. You need a way to get RTK reference data in, and a good
antenna. One approach is Vespucci (OSM editor for Android) as a
datalogger, and the Ardusimple WiFi NTRIP master to get corrections over
the phone's hotspot.
