3. Universal Setup (Trimble, Leica, Topcon, etc.)

Most professional survey rovers use different names for the same settings. Use this Translation Dictionary to configure your device correctly.

Step A: Configure the NTRIP Caster

Find the menu called "GNSS Contacts", "RTK Profiles", or "Internet Source".

Standard Term	Trimble / Spectra	Leica Geosystems	Topcon / Sokkia	Your Value
IP / Host	IP Address / URL	Server	IP Address	rtk.rtkdata.com (Select region)
Port	IP Port	Port	Port	2101
Mountpoint	Mountpoint	Mountpoint	Source	AUTO
User	NTRIP Username	User ID	User	(From Dashboard)
Password	NTRIP Password	Password	Password	(From Dashboard)

Step B: The "Data Format" Trap

Your rover will ask what format to expect.

• Correct Setting: RTCM 3.2 (or RTCM 3.X, Auto).

• Avoid: CMR, CMR+, RTCM 2.3.

Step C: NMEA Output (Crucial!)

Since we use Nearest Base technology, you must send your position to the server.

• Find the setting: "Send GGA" or "NMEA Output".

• Set it to: ON (or "1 second", "0.1 Hz").

• Without GGA, the server will not send any corrections.

4. Troubleshooting Common Rover Issues

Status: "Source Table Not Found"

• Cause: Your device cannot resolve the domain name (DNS issue).

• Fix: Try using the numeric IP address instead of the domain (e.g., use 3.73.41.96 for EU).

Status: "Connected" but "Latency > 5s"

• Cause: You are using the default Port 80, which is often throttled by mobile carriers.

• Fix: Change Port to 2101.

Status: "Float" (No Fixed Solution)

• Cause 1: You are indoors or near a wall. Go to open sky.

• Cause 2: You manually selected a distant Mountpoint.

• Fix: Change Mountpoint to AUTO to force the nearest station.

Need a Config File? For some legacy devices (Trimble TSC3, Leica CS15), we can generate a configuration file. Contact Support with your exact controller model.
