Step‑by‑step

1

1) Connect receiver & pick COM

Attach antenna, connect USB, open u‑center, and select the correct COM port. Confirm a basic position (e.g., 3D).

2

2) Open the NTRIP client

Receiver → NTRIP Client… to open the NTRIP window.

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) Verify connection & FIX

The NTRIP icon turns green when streaming. Watch solution evolve Autonomous → RTK Float → RTK FIX.

Tips

• Use OPEN SKY for faster convergence

• If stuck on FLOAT: re‑check IP/port, credentials, mountpoint = AUTO; reconnect
