This guide addresses the most common RTK issues with DJI drones: Mavic 3 Enterprise, Matrice 4 Enterprise, Matrice 350 RTK, Phantom 4 RTK, Inspire 3, and Agras series. If your DJI drone shows "Converging" but never reaches "FIX", start here.
"Converging" — RTK Not Reaching FIX
DJI drones are strict about RTK status. They require a stable FIX before enabling RTK-assisted flight. "Converging" means the drone is receiving corrections but hasn't locked to centimeter accuracy yet.
Decision Tree: What To Do
RTK shows "Converging" for more than 2 minutes
|
+-- Are you within 30 km of a base station?
| |
| +-- YES --> Check environment (open sky? no buildings/trees nearby?)
| | |
| | +-- Good sky view --> Wait up to 3 minutes. Try restart sequence below.
| | +-- Obstructed --> Move to open area, restart.
| |
| +-- NO --> Check distance on Coverage Map
| |
| +-- 30-50 km: FIX possible but sensitive. Be patient, ensure perfect sky view.
| +-- 50+ km: FIX unlikely. Consider Float-mode flight or local base station.
|
+-- Is your internet connection stable?
|
+-- Weak hotspot / VPN active --> Switch to stronger connection, disable VPN
+-- Stable 4G/5G --> Continue troubleshooting below
Distance Matters
Distance to the nearest base station is the single biggest factor for DJI RTK success. Check the RTKdata Coverage Map before flying — if you're within the colored zones, RTK FIX is achievable.
If you are far from the nearest station and stuck on "Converging" — distance is likely the issue, not your settings.
Pre-Flight RTK Checklist
Follow this exact sequence every time:
Power on the drone outdoors (not indoors, not in a vehicle)
Wait for GNSS satellite lock — DJI Pilot 2 shows satellite count (need 10+ for best results)
Verify internet connection on the controller (Wi-Fi, hotspot, or 4G dongle)
Enable Network RTK in DJI Pilot 2
Wait for RTK FIX — keep the drone stationary on the ground
Do NOT move the drone during convergence — DJI needs a stable initialization
Once FIX is achieved, you can take off
Battery Swap Procedure
Swapping the battery resets the RTK module. The drone must re-converge from scratch.
After every battery swap:
Power on the drone (keep it on the ground)
Wait for satellite lock (check satellite count in DJI Pilot 2)
Re-enable Network RTK if it doesn't auto-reconnect
Wait for FIX before takeoff — this may take 30–90 seconds
Do NOT rush — starting a mission before FIX will result in poor accuracy
Common DJI Error Messages
"No RTK Data Available"
Causes:
Selected "D-RTK 2 Mobile Station" instead of "Custom Network RTK"
On Agras drones: D-RTK 2 search is enabled and conflicts with network RTK
Drone does not have a GNSS fix yet (needs satellites first, then RTK)
Fix:
Go to RTK settings in DJI Pilot 2
Select Custom Network RTK (not D-RTK 2)
On Agras: disable "D-RTK 2 Search" toggle
Ensure the drone has satellite lock before enabling RTK
"Fail to Enable Network RTK"
Check controller internet connection
Verify NTRIP settings: Host, Port 2101, Mountpoint AUTO
Toggle RTK off → wait 5 seconds → toggle on again
If persistent: restart DJI Pilot 2 app completely
"RTK Signal Weak"
This usually means FLOAT status with poor convergence:
Check distance to nearest base station
Improve sky view (avoid buildings, trees, metal structures near takeoff)
Ensure stable internet (latency matters for RTK)
Map Pilot Pro vs. DJI Pilot 2
If you use Map Pilot Pro (by Maps Made Easy) instead of DJI Pilot 2:
Map Pilot Pro has its own NTRIP settings — it does NOT inherit RTK settings from DJI Pilot 2
Use port 2101 (NOT port 2103 which some versions default to)
You must configure Host, Port, Mountpoint, and Credentials separately in Map Pilot Pro
After configuring, verify RTK status within Map Pilot Pro before starting a mission
"Allow Takeoff in Float" Setting
DJI Pilot 2 has an option to allow takeoff even when RTK is in FLOAT (not FIX):
Where: RTK Settings > Allow Non-Fixed RTK Takeoff
When to use: When you're in a 30-50 km zone and FIX is intermittent
Accuracy in Float: Typically 10-30 cm (enough for photogrammetry, not for survey-grade GCPs)
Warning: Your flight data will be tagged as FLOAT, which may affect processing in DJI Terra or Pix4D
DJI Drone Compatibility
All DJI Enterprise/Agras drones with RTK capability work with RTKdata:

Mavic 3 Enterprise RTK
Built-in
Most popular model
Matrice 4 Enterprise RTK
Built-in
Newest model
Matrice 350 RTK
Built-in
Heavy-lift platform
Matrice 300 RTK
Built-in
Previous generation
Phantom 4 RTK

Legacy, still supported
Inspire 3
Built-in
Cinema/survey platform
Agras T50/T40/T25

Requires stable internet at dock
DJI consumer drones (Mini, Air, Mavic 3 non-Enterprise) do NOT have RTK capability and cannot use RTKdata.
Internet Connection Tips for DJI
DJI drones need a stable internet connection on the controller (not the drone itself):
Method
Reliability
Notes
Phone hotspot (4G/5G)
Good
Most common setup
USB 4G dongle on controller
Very good
Recommended for field work
Controller built-in 4G (RC Plus)
Excellent
Best option if available
Wi-Fi from nearby building
Variable
Signal may drop in flight
Tips:
Keep the hotspot device close to the controller
Disable VPN — it adds latency that degrades RTK
If connection drops mid-flight, RTK will switch to FLOAT automatically (flight continues safely)
Still Not Working?
Before contacting support, please note:
Your drone model and DJI Pilot 2 version
Your location (country/region)
Distance to nearest base station (check Coverage Map)
