Trimble GFX-750 / XCN-1050 (Precision-IQ)

These steps connect a Trimble GFX-750 / XCN-1050 (Precision-IQ) to the Premium Positioning correction network over NTRIP, using Precision-IQ. They assume you already have your NTRIP credentials.

Before you start

• Your NTRIP username and password, from your Premium Positioning welcome email or your account on the customer portal.

• Precision-IQ.

• A working internet connection on the controller or phone.

• A clear view of the sky at the point you are measuring.

Network settings

These are the same for every Premium Positioning customer. Only your username and password are unique to you.

• Server or host: rtkpremium.xyz

• Port: 2101

• Mountpoint: COMMON

• Protocol: NTRIP

Steps

1. Have your details ready: You need your personal NTRIP username and password (from your PP welcome email) plus a working internet connection for the display. The caster details are the same for every customer; only your username/password are unique.

2. Get the display online (Wi-Fi or modem): NTRIP arrives over the internet, so connect the display first. On the GFX-750 / XCN-1050 (Android-based), swipe down from the top and open Wi-Fi settings, then join a hotspot or Wi-Fi network (e.g. your phone's hotspot or an in-cab modem). If you use a built-in/connected cellular modem, confirm it shows a data connection. Wording varies by firmware - the goal is live internet.

3. Open Precision-IQ and go to GNSS settings: From the Launcher tap Precision-IQ. On the Home screen tap the GNSS tile (on some firmware via Settings > GNSS Setup). The GNSS details page shows the NAV-900 receiver and current correction source.

4. Edit the correction source: On the GNSS details page tap Edit. The Corrections option is selected by default; the Correction Source / Service is set to Autonomous - you'll change this to an internet RTK source.

5. Select the internet / NTRIP correction source: Tap Correction Service (Correction Source on some versions) to open the list and choose the internet RTK option - shown as an NTRIP / Internet / VRS entry, or under a Modem setting as 'Third Party NTRIP Modem'. Pick the option that lets you type a server address, port and mountpoint (not a radio frequency or satellite service). If unsure which entry, contact Premium Positioning support first.

6. Enter the caster server address: In the server field (Server Name/Address, Server, or IP Address depending on firmware), enter exactly: rtkpremium.xyz

7. Enter the caster port: In the port field (Server Port Number, Port, or IP Port), enter exactly: 2101

8. Enter or select the mountpoint: In the Mountpoint field enter exactly: COMMON (capitals). If the display offers a button to retrieve the source table once server and port are entered, tap it and choose COMMON. The protocol is standard NTRIP - leave any NTRIP version setting on its default (auto).

9. Enter YOUR NTRIP username and password: Type the NTRIP username and password from your welcome email - unique to your account, case-sensitive; do not share them. If lost, contact Premium Positioning to reissue.

10. Save the settings: Apply/confirm (tick/Save), then tap Home. The receiver attempts to connect over the internet and start streaming corrections.

11. Let the receiver connect and converge: With the vehicle outdoors under clear sky, watch the GNSS status indicator on the Home screen move from Autonomous toward a corrected solution. The first connection can take a short while.

12. Confirm RTK Fixed: Check the GNSS status / accuracy indicator until it reports RTK Fixed (cm-level). That confirms the COMMON corrections from rtkpremium.xyz are being received and applied. If it stays Autonomous/converging, recheck the internet connection, then server / port / mountpoint and your credentials.

If the fix will not hold

Screen/button/field names vary by display model and Precision-IQ firmware ('Correction Service' vs 'GNSS Setup', an 'NTRIP/Internet' entry vs 'Third Party NTRIP Modem') - described generically where they differ. The display needs live internet (Wi-Fi/hotspot or a connected cellular modem). If anything on your screen doesn't match, contact Premium Positioning before changing other settings.
