FieldGenius for Android

These steps connect a FieldGenius for Android to the Premium Positioning correction network over NTRIP, using FieldGenius for Android app. 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.

• FieldGenius for Android app.

• 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 connect to the internet: Turn on your GNSS receiver and your Android device. FieldGenius sends NTRIP corrections over the data collector's connection, so make sure the Android device has internet (SIM or hotspot/Wi-Fi). FieldGenius works with many receiver brands (Emlid, Leica, Trimble, Topcon, CHCNAV, Stonex and others) via its drivers.

2. Open your project: Launch FieldGenius for Android and open or create a project to reach the main map screen.

3. Select the GNSS instrument profile: Tap 'Select Instrument', choose 'GNSS Rover' and add a new profile (name it after your receiver). For receivers without a dedicated driver, a generic profile (Make 'NMEA', Model 'Basic') is common - pick the named brand driver if listed.

4. Set up Bluetooth communication: Open 'Set Up Communication' (older builds: Edit → 'Model and Communication'). Set connection type to 'Bluetooth', tap 'Search', select your receiver, pair (some prompt for a PIN such as 123456), then 'Connect' and confirm it's connected.

5. Open the corrections / data source setup: Open 'Set Up Corrections' (or the three-dot menu next to 'Corrections' on the GNSS Rover screen). Older builds: Instrument Settings → 'Link Configure'. Wording varies by version - look for the corrections/reference data-source area.

6. Choose internet (NTRIP) corrections: Choose 'RTK via Internet' with the link device set to 'Data collector' ('Data Collector Internet') so FieldGenius streams NTRIP through the Android connection rather than a radio or the receiver's modem.

7. Add a new NTRIP correction source: Tap 'Set Up Data Source' then 'Add New Source' (older builds: 'Press to Modify' → NTRIP Casters → 'Add').

8. Enter the Premium Positioning caster: Name: any label (e.g. 'Premium Positioning'); Address / Server / Host: rtkpremium.xyz; Port: 2101; Protocol: NTRIP. Leave the mount point empty for now.

9. Enter your NTRIP username and password: Enter YOUR OWN NTRIP credentials from your Premium Positioning welcome email - unique to your account. Save the source ('Done').

10. Connect and retrieve the source table: Select the source and tap 'Connect'. FieldGenius downloads the NTRIP source table (mountpoints). Wait for the port to finish configuring.

11. Select the COMMON mountpoint: From the source table choose COMMON. If your account has one stream it may already be selected; otherwise tap COMMON.

12. Confirm correction format and NMEA, then the mountpoint: Check 'Correction Format' (e.g. RTCM 3.x) and 'NMEA Required' - most network/VRS services need NMEA sent back, so leave it enabled unless told otherwise. Tap 'Confirm Selected Mountpoint' and wait for the link to configure.

13. Set antenna height and tolerances: Enter your antenna/pole height and accuracy tolerances so stored points meet your job's requirements. Tap 'Done' to return to the survey screen.

14. Confirm a Fixed solution: Watch the status move Autonomous → Float → RTK Fix. The receiver LED usually turns solid green when fixed. Collect points only once Fixed is stable. If it stays Float/Autonomous, re-check internet, the COMMON mountpoint, credentials, and sky view.

If the fix will not hold

FieldGenius for Android is receiver-agnostic and supports many brands via its driver list, so wording differs slightly between versions/drivers - if a label doesn't match, find the nearest equivalent ('Set Up Data Source' vs 'Link Configure', 'Set Up Communication' vs 'Model and Communication'). Caster settings are the same for everyone; your username/password are personal and entered on the device only.
