# DJI RTK Troubleshooting

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](https://rtkdata.com/coverage/) 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:

1. **Power on the drone outdoors** (not indoors, not in a vehicle)
2. **Wait for GNSS satellite lock** — DJI Pilot 2 shows satellite count (need 10+ for best results)
3. **Verify internet connection** on the controller (Wi-Fi, hotspot, or 4G dongle)
4. **Enable Network RTK** in DJI Pilot 2
5. **Wait for RTK FIX** — keep the drone stationary on the ground
6. **Do NOT move the drone** during convergence — DJI needs a stable initialization
7. 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:**

1. Power on the drone (keep it on the ground)
2. Wait for satellite lock (check satellite count in DJI Pilot 2)
3. Re-enable Network RTK if it doesn't auto-reconnect
4. Wait for FIX before takeoff — this may take 30–90 seconds
5. 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:**

1. Go to RTK settings in DJI Pilot 2
2. Select **Custom Network RTK** (not D-RTK 2)
3. On Agras: disable "D-RTK 2 Search" toggle
4. Ensure the drone has satellite lock before enabling RTK

### "Fail to Enable Network RTK"

1. Check controller internet connection
2. Verify NTRIP settings: Host, Port `2101`, Mountpoint `AUTO`
3. Toggle RTK off → wait 5 seconds → toggle on again
4. 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:

| Drone                    | RTK Module | Notes                            |
| ------------------------ | ---------- | -------------------------------- |
| 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            | Built-in   | Legacy, still supported          |
| Inspire 3                | Built-in   | Cinema/survey platform           |
| Agras T50/T40/T25        | Built-in   | Agricultural spraying            |
| DJI Dock 2               | Remote RTK | 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)
