# 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) *** ## Still Not Working?
