Connecting to an NTRIP caster
What's an NTRIP caster? In a nut shell it's a server that is sending out correction data every second. There are
thousands of sites around the globe that calculate the perturbations in the ionosphere and troposphere that
decrease the accuracy of GNSS accuracy. Once the inaccuracies are known, correction values are encoded into
data packets in the RTCM format. You, the user, don't need to know how to decode or deal with RTCM, you simply
need to get RTCM from a source within 10km of your location into the RTK Surveyor. The NTRIP client logs into
the server (also known as the NTRIP caster) and grabs that data, every second, and sends it over Bluetooth to the
RTK Surveyor.
mode to provide RTCM correction data but it
will less accurate than a fixed position caster.
Once you have a full RTK fix you'll notice the location bubble in SW Maps turns to green. Just for fun, rock your
rover monopole back and forth on a fixed point. You'll see your location accurately reflected in SW Maps.
Millimeter location precision is a truly staggering thing.
