# Skydio X10 / X10D NTRIP Setup: Centimeter RTK

Connect the **Skydio X10** (and the **X10D** variant) to RTKdata.com's NTRIP correction service for centimeter-level positioning. RTK and PPK on the X10 are provided by an **optional modular RTK/PPK attachment** — they are not built into the base airframe.

{% hint style="danger" %}
A base X10 **without** the **Skydio RTK/PPK attachment** (part number `DR4ATTRTK`) has no RTK or PPK capability. The attachment is powered by a **Septentrio Mosaic-X5** multi-constellation GNSS receiver and supports both real-time **RTK** (corrections in flight) and **PPK** (post-processed after landing). This guide covers the real-time **NTRIP RTK** workflow.
{% endhint %}

## Requirements

* **Aircraft:** Skydio X10 or X10D with the **RTK/PPK attachment** (`DR4ATTRTK`) installed in an attachment bay
* **Controller:** Skydio controller with an active internet connection (phone hotspot or tether — the controller, not the aircraft, carries the NTRIP stream)
* **Firmware:** Aircraft, attachment, and controller updated to the latest version
* **RTKdata account:** Active subscription with NTRIP credentials

{% endhint %}

## Step-by-step setup

{% stepper %}
{% step %}

### Install the RTK/PPK attachment

Mount the **RTK/PPK attachment** in one of the X10's attachment bays and power on the aircraft and controller. Confirm the controller has internet (hotspot or tether).
{% endstep %}

{% step %}

### Open RTK setup

On the controller, go to **Global Settings → Attachments → RTK/PPK → Set Up RTK**.
{% endstep %}

{% step %}

### Open network settings

Under **Connect to Base Station**, tap **Open Network Settings**. Set **Kinematics Type** to **RTK** (not PPK).
{% endstep %}

{% step %}

### Enter NTRIP connection settings

Select your region and enter the corresponding server details:

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

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

{% tab title="Europe" %}

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

{% tab title="Australia" %}

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

The controller loads the available mount points from the caster's source table — select **`AUTO`** from the list.

{% hint style="danger" %}
**Keep "Send GGA" enabled.** The RTKdata caster uses your GGA position to select the **nearest reference station** and stream single-baseline RTCM3 corrections from it. Without GGA, you connect but receive no corrections and stay on Float. RTKdata is a single-baseline, location-keyed network — it is **not** a VRS service. See [NTRIP & GGA Essentials](/integration-hub/ntrip-clients-and-field-software/ntrip-and-gga-essentials.md).
{% endhint %}
{% endstep %}

{% step %}

### Connect and verify Fix

* Tap **Connect Now** (Connect to Base Station).
* Place the drone **outdoors** with a clear sky view so the Mosaic-X5 acquires satellites before it can report position to the caster.
* Watch the RTK status indicator (top-right telemetry):

| Status     | Meaning                                                  |
| ---------- | -------------------------------------------------------- |
| **SINGLE** | Basic GNSS fix. No corrections applied yet.              |
| **FLOAT**  | Corrections received and processing. Accuracy improving. |
| **FIX**    | Centimeter-level accuracy active.                        |

Skydio requires an RTK **FIX** before proceeding with the flight. Convergence typically takes 30–90 seconds in open sky.
{% endstep %}
{% endstepper %}

## Vertical reference (heights)

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

## Troubleshooting

| Problem                         | Cause                                     | Fix                                                                                                |
| ------------------------------- | ----------------------------------------- | -------------------------------------------------------------------------------------------------- |
| No corrections / stuck on Float | GGA not being sent (no satellite fix yet) | Move outdoors to open sky so the receiver acquires satellites and reports position                 |
| No corrections                  | No internet on the controller             | Verify the controller's hotspot/tether connectivity                                                |
| Authentication fails            | Wrong credentials                         | Re-enter username/password from the RTKdata dashboard (case-sensitive, username starts with `rtk`) |
| Mount point not listed          | Source table not loaded                   | Re-open Network Settings so the controller refreshes the source table, then select `AUTO`          |
| RTK option missing              | Attachment not installed/detected         | Confirm the RTK/PPK attachment is seated in a bay and firmware is current                          |

## Tips

* **The RTK/PPK attachment is required.** Without `DR4ATTRTK`, the X10 cannot do RTK or PPK.
* **Internet runs through the controller**, not the aircraft — use a stable hotspot or tether.
* **PPK is also available** via the same Mosaic-X5 attachment if you prefer post-processing over real-time corrections.
* **Update firmware first** (aircraft, attachment, controller) before troubleshooting connectivity.
