RTK location calibration on the DJI Dock 3 gives you centimeter-level positioning accuracy for automated flights. The Dock 3 process has two stages: Location Convergence, then Location Calibration.
Proper dock location calibration allows the RTK module to lock onto accurate coordinates, giving you centimeter-level positioning in the field. Work through the steps below to get it done.
Before you begin
| ℹ️ Note: If the dock is ever physically relocated, you'll need to run calibration again. As long as it hasn't moved, your calibration data will hold; restarting the dock won't wipe it. |
- Keep the area around the dock clear. The RTK antenna needs an unobstructed line of sight, so don't stand close while calibration is running.
- Make sure your smartphone has an active internet connection before you begin. This is needed for Custom Network RTK calibration.
- Have the DJI app open and the dock powered on before you start.
Steps
Open the calibration flow in the app
Head to the dock setup screen in the app. From here, you'll move through two stages: Location Convergence and Location Calibration.
Wait for location convergence
Once the RTK module has locked on, the app will show the converged coordinates and ellipsoid height. Hold off on proceeding until the status reads Converged and Fixed.
Choose your calibration method
Tap Calibration and pick the method that fits your setup:
- Custom Network RTK Calibration (recommended): delivers better accuracy and is generally easier to complete. An active internet connection is required.
Manual Calibration: a good fallback if you don't have access to a custom RTK network.
Confirm dock location is determined
When calibration finishes, the app will show "Dock location determined" alongside a green checkmark. Your dock is now ready for centimeter-level accuracy during flight operations.
After calibration
- It's common for the aircraft RTK positioning data to appear to shift suddenly right after calibration. Don't be alarmed. A quick aircraft restart will dismiss the prompt.
- When loading flight routes through DJI FlightHub 2, make sure the RTK signal source you fly with is the same one used during calibration. If they don't match, the aircraft may stray from its intended path, producing unsatisfactory data or a crash.
- Any time you open the dock cover through the app, stand well clear to avoid getting caught by the moving cover. Hit the emergency stop button on the dock if you need to halt it immediately.
