Step‑by‑step

1

1) Bluetooth GNSS & pole height

Menu → Bluetooth GNSS → Scan → Connect to your rover. Set Instrument model (e.g., SparkFun RTK or Generic NMEA) and Instrument height (e.g., 2.00 m).

2

2) Create NTRIP profile

Open NTRIP Client and add a profile for your region.

3

Enter RTKdata.com connection settings (Regional hostnames + IP fallback)

Use the regional RTKdata.com hostname where possible. If your device only accepts numbers or your network DNS blocks hostnames, use the numeric IP fallback. Keep ALL CAPS where noted.

North America

• Host (domain): rtk.rtkdata.com

• Host (IP fallback): 13.56.117.10

• Port: 2101

• Username / Password: your RTKdata.com credentials

• Mountpoint (ALL CAPS): AUTO (recommended) — or AUTO_WGS84, AUTO_ITRF2020, AUTO_ITRF2014

Europe

Australia

Only these four mountpoints are valid. Typing local CRS names as mountpoints will result in no corrections. Always use ALL CAPS.

4) Enable GGA & connect

Toggle Send NMEA GGA to caster = ON, then Connect. Watch the solution transition to RTK FIX (many themes show a green position marker on FIX).

Tips

• If heights look “off”, remember the rover reports ellipsoidal heights; apply a geoid in GIS for orthometric.

• If stuck on FLOAT, verify open sky, correct regional IP, and mountpoint = AUTO.
