# DJI Matrice 4 Enterprise RTK

Connect the **DJI Matrice 4 Enterprise RTK** (4E RTK or 4T RTK) to RTKdata.com for centimeter-level positioning. This guide also covers configuration for the **DJI Dock 2** autonomous docking station.

## Requirements

* **Aircraft:** DJI Matrice 4 Enterprise RTK (4E RTK or 4T RTK) — the non-RTK variant does not support network corrections
* **Controller:** DJI RC Plus or DJI RC Pro Enterprise
* **Software:** DJI Pilot 2 — updated to the latest version with Matrice 4 series support
* **Firmware:** Aircraft and controller firmware updated to the latest version
* **Internet:** Phone Wi-Fi hotspot or USB 4G dongle connected to the controller
* **RTKdata account:** Active subscription with NTRIP credentials

## Step-by-step setup

{% stepper %}
{% step %}

#### Power on and link

Power on the Matrice 4 Enterprise RTK and the controller. Wait for the link to establish.
{% endstep %}

{% step %}

#### Connect to the internet

Connect the controller to the internet via Wi-Fi hotspot or 4G dongle. Verify connectivity by opening a browser.
{% endstep %}

{% step %}

#### Open DJI Pilot 2

Launch **DJI Pilot 2** and enter the **camera/flight view**.
{% endstep %}

{% step %}

#### Open RTK settings

* Tap the **three dots (...)** icon in the top-right corner of the screen
* Select the **RTK** tab in the left sidebar of the settings panel
* Toggle **RTK Positioning** to **ON**
  {% endstep %}

{% step %}

#### Select Custom Network RTK

Under "RTK Service Type", select **Custom Network RTK**.
{% endstep %}

{% step %}

#### Enter NTRIP connection settings

Select your region and enter the corresponding server details:

{% tabs %}
{% tab title="North America" %}

* **Host (domain):** `rtk.rtkdata.com`
* **Host (IP fallback):** `13.56.117.10`
* **Port:** `2101`
* **Username / Password:** From *RTK Credentials* in the internal dashboard (not website login)
* **Mountpoint (ALL CAPS):** `AUTO` (recommended) — or `AUTO_WGS84`, `AUTO_ITRF2020`, `AUTO_ITRF2014`
  {% endtab %}

{% tab title="Europe" %}

* **Host (domain):** `eu.rtkdata.com`
* **Host (IP fallback):** `3.73.41.96`
* **Port:** `2101`
* **Username / Password:** From *RTK Credentials* in the internal dashboard (not website login)
* **Mountpoint (ALL CAPS):** `AUTO` (recommended) — or `AUTO_WGS84`, `AUTO_ITRF2020`, `AUTO_ITRF2014`
  {% endtab %}

{% tab title="Australia" %}

* **Host (domain):** `aus.rtkdata.com`
* **Host (IP fallback):** `54.206.56.130`
* **Port:** `2101`
* **Username / Password:** From *RTK Credentials* in the internal dashboard (not website login)
* **Mountpoint (ALL CAPS):** `AUTO` (recommended) — or `AUTO_WGS84`, `AUTO_ITRF2020`, `AUTO_ITRF2014`
  {% endtab %}
  {% endtabs %}

{% hint style="warning" %}
Only these four mountpoints are valid. Typing local CRS names as mountpoints will result in **no corrections**. Always use **ALL CAPS**.
{% endhint %}
{% endstep %}

{% step %}

#### Connect and verify

* Tap **Connect** to save and initiate the connection
* Move **outdoors** to an open area with clear sky view — the Matrice 4 needs a satellite fix before it sends position data to the NTRIP server
* Monitor the RTK status indicator in DJI Pilot 2:

| Status     | Color  | Meaning                                                 | Typical Duration |
| ---------- | ------ | ------------------------------------------------------- | ---------------- |
| **SINGLE** | Red    | Basic GNSS fix acquired. No corrections yet.            | Immediate        |
| **FLOAT**  | Yellow | Correction data is being received and processed.        | 10–30 seconds    |
| **FIX**    | Green  | Centimeter-level accuracy achieved. Std dev below 2 cm. | 30–60 seconds    |

The Matrice 4's improved multi-frequency GNSS antenna converges noticeably faster than older DJI enterprise platforms.

{% hint style="info" %}
For autonomous mapping flights, wait until you see **FIX** status before launching the mission. This ensures all geotagged photos have centimeter-level accuracy from the start.
{% endhint %}
{% endstep %}
{% endstepper %}

## DJI Dock 2 configuration

The Matrice 4 Enterprise RTK is compatible with the **DJI Dock 2** for fully autonomous remote operations.

{% stepper %}
{% step %}

#### Open FlightHub 2

Configure the NTRIP settings in **DJI FlightHub 2** (cloud platform), not in DJI Pilot 2.
{% endstep %}

{% step %}

#### Navigate to RTK settings

Open the dock's RTK configuration panel in FlightHub 2.
{% endstep %}

{% step %}

#### Enter RTKdata.com credentials

Enter the same RTKdata.com credentials and server settings listed in the tabs above.
{% endstep %}

{% step %}

#### Verify connectivity

The Dock 2 uses its own built-in internet connection (Ethernet or 4G), so the controller's connectivity is not relevant for remote missions.
{% endstep %}
{% endstepper %}

{% hint style="info" %}
Dock-based operations require the Dock 2 to have a reliable internet connection at all times. Contact RTKdata.com support if you need assistance configuring NTRIP with DJI Dock 2 and FlightHub 2.
{% endhint %}

## Vertical reference (heights)

{% hint style="info" %}
RTK corrections deliver **ellipsoidal heights** (height above the WGS 84 ellipsoid), not orthometric heights (height above mean sea level). If your workflow requires orthometric heights, apply a geoid model in your post-processing software.
{% endhint %}

## Troubleshooting

| Problem                      | Cause                  | Fix                                                                                               |
| ---------------------------- | ---------------------- | ------------------------------------------------------------------------------------------------- |
| RTK tab not visible          | Non-RTK model          | Verify your Matrice 4 is the RTK variant. The standard model does not show RTK settings.          |
| RTK tab not visible          | Outdated Pilot 2       | Update DJI Pilot 2. Early releases may not fully support the Matrice 4 series.                    |
| Stuck on FLOAT               | Obstructed environment | Move to an open area away from buildings, dense trees, and metal structures.                      |
| Stuck on FLOAT               | Out of range           | Verify your RTKdata subscription is active and you are within 50 km of a base station.            |
| Connection fails immediately | Wrong port             | Confirm the port is `2101` (not 2102, 8080, or other defaults from other services).               |
| Connection fails immediately | Wrong credentials      | Verify credentials are from the RTKdata dashboard, not your website login.                        |
| Corrections drop mid-flight  | Unstable internet      | A USB 4G dongle provides more reliable connectivity than a phone hotspot, especially at altitude. |

## Tips

* **Firmware updates are critical.** As a 2025 platform, DJI is actively releasing firmware improvements. Always run the latest version for best RTK performance and stability.
* **Faster convergence.** The Matrice 4 has a larger multi-frequency RTK antenna than the Mavic 3 Enterprise, resulting in faster convergence and better multipath rejection near buildings.
* **For photogrammetry workflows**, keep RTK enabled for the entire flight rather than just during takeoff. This ensures every photo is geotagged with corrected coordinates.
* **Pre-flight checklist:** Power on, wait for satellite lock, verify FIX status, then start your mission. Skipping FIX verification is the most common source of inaccurate survey data.
* **After a battery swap**, allow 30–60 seconds for RTK to re-converge before resuming the mission.
* **Dual controller support.** If using two RC Plus controllers, only the master controller needs internet for RTK. The slave controller does not handle RTK connectivity.
