Leica GS16 / GS07

These steps connect a Leica GS16 / GS07 to the Premium Positioning correction network over NTRIP, using Leica Captivate (CS20). 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.

• Leica Captivate (CS20).

• 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. Power up and pair the receiver: Switch on the GS16/GS07 and the CS20. The CS20 normally pairs to the receiver over Bluetooth automatically. If not, on the Captivate Home screen open Settings > Connections > GS Sensor (wording varies by version) and confirm the controller is connected before continuing.

2. Set up the internet connection: The rover needs internet. On the Home screen go to Settings > Connections > Internet connection. Tap New, then choose how you get online - Bluetooth to your phone's hotspot, or a CS20 SIM/cellular modem. Follow the prompts (enter your carrier's APN if asked). Confirm the connection shows connected.

3. Open the RTK rover wizard / RTK rover profile: Under Settings > Connections, open the RTK rover entry ('RTK rover wizard' or an 'RTK rover' profile screen by version). Tap New (or Edit) to create a correction profile and name it, e.g. 'Premium Positioning'.

4. Choose Internet as the real-time device: When asked how corrections are received, set the real-time device/connection to your Internet connection (not a radio), so Captivate streams over the internet.

5. Set the network type to NTRIP: On the network/server settings, set Network type (sometimes 'RTK network' or 'Server type') to NTRIP, so the receiver logs in to the caster and pulls a mountpoint rather than a Direct IP feed.

6. Enter the caster server and port: Create/edit the server entry: Server / Host: rtkpremium.xyz, Port: 2101. The field may be 'Server', 'Host' or 'Address' by version. Save the server.

7. Enter your NTRIP username and password: On the NTRIP tab (or the credential fields on the server screen), enter the NTRIP User ID and Password from your welcome email - unique to your account; entered into the device only.

8. Select the COMMON mountpoint: Pick it from the source table: tap the Source-table / SRCE button (or 'Get source table' / the mountpoint dropdown) so Captivate lists available mountpoints, then select COMMON. If the source table is slow or empty, type COMMON manually (capitals).

9. Confirm the data format: If prompted for a correction format, leave it on the standard RTCM 3.x that matches COMMON. Captivate usually detects this automatically from the mountpoint.

10. Enable Send GGA position: Ensure 'Send GGA position' is On / Automatic - the caster uses your GGA to send the right corrections; with it off you may never reach Fixed. Usually automatic for a single fixed mountpoint, but confirm.

11. Finish the wizard and connect: Step through the remaining pages with Next (F6) and Finish/Store. Captivate dials the internet connection and logs in to the caster. Watch for 'Connected to NTRIP caster' and check the status-bar connection icon is active (no orange warning).

12. Start the survey and check correction flow: Start a survey using the new profile. Confirm corrections arrive - the real-time icon should be active and position quality should drop from autonomous/Float toward cm-level.

13. Confirm RTK Fixed: Wait for Fixed (phase-fixed) with a coordinate quality (CQ) at cm level - typically within a minute or two. Then you're ready to measure and stake. If it stays Float, recheck COMMON, that Send GGA is On, your credentials, and a stable internet/open-sky view.

If the fix will not hold

Menu/button names vary between Captivate versions (RTK rover wizard vs RTK rover profile, Server vs Host). The same workflow applies to GS16 and GS07 on a CS20. Tip: if the source table is slow or empty, the internet connection usually isn't up yet - fix that first, or type COMMON manually.
