Auterion NTRIP App Setup: Freefly & Skynode RTK

Connect Auterion drones like Freefly Astro and Inspired Flight to RTKdata via Third-Party RTK. Caster details and AUTO mountpoint for centimeter RTK.

Auterion-based drones — including the Freefly Astro and Inspired Flight IF800 / IF1200 — receive RTK corrections through the Auterion NTRIP app, which has a Third-Party RTK option for connecting to a caster like RTKdata.com.

Requirements

• Auterion-based aircraft (e.g. Freefly Astro, Inspired Flight IF800 / IF1200) with an RTK GNSS module

• The Auterion NTRIP app on the controller

• Internet on the controller

• Active RTKdata.com account with RTK credentials

Step-by-step setup (pending field verification)

1

Open the Auterion NTRIP app

In the NTRIP app, tap the cogwheel (top-right) → Settings, enable Third-Party RTK, then enter the connection details and credentials and tap Apply. (Exact field labels for host/port/mountpoint are pending on-device confirmation.)

Enter your RTKdata caster details

North America

• Host: rtk.rtkdata.com (IP fallback 13.56.117.10)

• Port: 2101

• Username / Password: From RTK Credentials in the dashboard (username starts with rtk)

• Mountpoint (ALL CAPS): AUTO

Europe

• Host: eu.rtkdata.com (IP fallback 3.73.41.96)

• Port: 2101

• Username / Password: From RTK Credentials in the dashboard (username starts with rtk)

• Mountpoint (ALL CAPS): AUTO

Australia

• Host: aus.rtkdata.com (IP fallback 54.206.56.130)

• Port: 2101

• Username / Password: From RTK Credentials in the dashboard (username starts with rtk)

• Mountpoint (ALL CAPS): AUTO

RTKdata uses your GGA position to select the nearest reference station and stream single-baseline RTCM3 corrections — it is not a VRS service and sends nothing without a position. The Auterion app must forward the vehicle's position (GGA) to the caster. See NTRIP & GGA Essentials.

Verify RTK Fix

Confirm the vehicle reaches RTK Fixed before relying on it for a mapping mission.

Vertical reference (heights)

RTKdata delivers ellipsoidal heights (WGS 84 ellipsoid). Apply a geoid model in your processing if you need orthometric heights.
