Kolida K5 / K9T / K1 Pro

These steps connect a Kolida K5 / K9T / K1 Pro to the Premium Positioning correction network over NTRIP, using SurvX / SurvStar (Android). 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.

• SurvX / SurvStar (Android).

• 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. About this app: Kolida receivers run a SurvX-family Android app (SurvX / SurvStar), sharing the same SOUTH lineage and menu structure as SOUTH SurvX and SurPad. Labels below match SurvX 4.x; wording varies slightly between versions/translations - match the nearest equivalent.

2. Power on and pair: Turn on the Kolida K5 / K9T / K1 Pro and enable Bluetooth on your Android device. You don't have to pair in Android settings first; SurvX can pair during connection.

3. Open Device > Communication: In SurvX open Device > Communication. Set the device manufacturer/type to your Kolida receiver and choose Bluetooth.

4. Connect over Bluetooth: Tap Search. When your receiver's serial number appears in the Bluetooth Device List, tap it then Connect (tap Pair if prompted). Wait for connected status.

5. Open Device > Rover: Go to Device > Rover to open the rover mode settings - where you choose how corrections reach the receiver.

6. Choose the Data Link: In Data Link choose Device Internet (receiver's own SIM/modem) or Phone Internet (your Android device's mobile data). Either works for NTRIP; pick whichever has a data connection.

7. Set Connect Mode to NTRIP: Set Connect Mode (protocol) to NTRIP. Leave the GGA upload interval at its default unless told otherwise.

8. Enter the caster address and port: In CORS / server settings: Server / IP / address: rtkpremium.xyz, Port: 2101 - the same for every customer.

9. Enter YOUR NTRIP username and password: In CORS Settings enter the NTRIP User and Password from your welcome email - unique to you; do not share them.

10. Get the source table: In Mount Point Settings tap Get Mount Point (shown as Get Access Point when using Phone Internet) to retrieve the source table using your credentials.

11. Select mount point COMMON: From the list choose COMMON. Confirm/apply to start receiving corrections.

12. Confirm a Fixed solution: On the survey/map screen watch the status move Single → Float → Fixed (top status bar). Once Fixed, the receiver is on the network and ready for cm work. If it stays Single/Float, recheck the data link, credentials, mount point, and your mobile data.

If the fix will not hold

Kolida's SurvX / SurvStar is part of the SOUTH SurvX/SurPad software family, so these steps broadly apply to SOUTH and other SurvX-based controllers. Labels may differ slightly by app version; match the closest equivalent.
