# BeyondLine

## Overview

BeyondLine lets you fly Auterion-powered drones over the mobile network (3G/4G), without using a traditional radio link.\
Once enabled, both the drone and the Ground Control Station (GCS) connect through a secure private network, allowing you to operate the aircraft **from anywhere with Cellular coverage**.

This is the perfect solution for:

* BVLOS missions
* Remote inspections
* Emergency & disaster-response operations
* Distributed fleet management

{% hint style="warning" %}
This feature is available from **AMC v1.38.0** and requires an Auterion Suite **Enterprise** subscription. To obtain an Enterprise subscription, please contact us [here](https://auterion.com/company/contact-us/).
{% endhint %}

***

## **Before You Start**

#### **You Need**

* A drone equipped with a working LTE connection (SIM installed and active). Open the Quick Settings menu and make sure LTE is set to Active.
* Auterion Suite with an active **Enterprise** subscription.
* A Ground Control Station running **AMC v1.38.0 or later and logged** in with your Pilot Profile.
* **Tailscale Client** installed on your GCS device.

{% hint style="info" %}
Our BeyondLine technology leverages Tailscale VPN to establish the secure link between drone and GCS.

<figure><img src="https://3329189600-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FFW1Ge1p1f6WHyiYCb146%2Fuploads%2Fd9KqWgGasnx3uVYWhT6L%2FRemote%20Operations%20Interface%20with%20Available%20Vehicles%20(1).png?alt=media&#x26;token=d2bd62ae-d705-4c48-9103-d47e47c21c03" alt=""><figcaption></figcaption></figure>

{% hint style="info" %}
Pairing a vehicle links it to your current GCS, so it will **not** appear in the Remote Operations vehicle list on other ground control stations.
{% endhint %}

### Configuring Joysticks for Cellular Control

To use joystick commands over a cellular connection, you must configure the joystick correctly on Pilot Pro or any GCS with joystick support.

**1. Enable joystick input**

1. In AMC, go to **Controller → Joystick → General**.
2. Enable **Joystick input**.

<figure><img src="https://3329189600-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FFW1Ge1p1f6WHyiYCb146%2Fuploads%2FB9x02y6U1mBTAIyMVKwt%2FScreenshot_20251209_111221.jpg?alt=media&#x26;token=66256e7f-3a66-42ed-8a16-159413b3f5ce" alt=""><figcaption></figcaption></figure>

**2. Configure joystick parameters**

{% hint style="warning" %}
These parameter settings apply to AOS 4.3. For other AOS versions, check the corresponding [documentation](https://docs.px4.io/v1.16/en/advanced_config/parameter_reference#COM_RC_IN_MODE).
{% endhint %}

1. Enter **Advanced mode** by quickly clicking the **Auterion logo** in the top-left corner five times.
2. When the dialog appears, select **Switch to advanced**.
3. Open **Quick settings** by selecting the vehicle name in the top-right corner.
4. In **Quick settings**, open the **Safety** tab.
5. Locate the **Manual Control loss Failsafe Trigger** section.
   1. Set **Input Source Configuration** to **MAVL 1 > MAVL 2 > RC**. This prioritizes joystick (MAVLink) control over RC.
   2. Set **Manual Control loss timeout** to **1 s**. This defines how long the vehicle waits without a new RC or joystick command before it considers the control link lost.

<figure><img src="https://3329189600-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FFW1Ge1p1f6WHyiYCb146%2Fuploads%2FJ0K9H6atYDqu2MHGtcMf%2FScreenshot%202026-01-12%20at%2009.09.57.png?alt=media&#x26;token=5de1820f-70d1-4acd-a6ef-38771d7596d0" alt=""><figcaption></figcaption></figure>

#### Verifying LTE Connectivity

To ensure your link is working with LTE after having completed the setup:

**On a GCS with 2 links:**

When two links are active, the Dual Link icon is shown in the top header bar.

1. Select the **Dual Link** icon.
2. In the pop-up, select the **LTE** connection.
3. On your GCS, disable the LTE and WiFi connection.

The Dual Link icon updates to show the new active link (in this case the Primary Radio link).

### Safety Notes for Operators

* Confirm **stable LTE signal** before arming the drone, especially for BVLOS.
* Follow all applicable **local aviation regulations**.
* If latency increases, avoid low-altitude or high-precision flying.
* Keep a fail-safe procedure ready (RTH, geofence, or backup link if available).

### Updating from early C2 over LTE versions

{% hint style="warning" %}
If the vehicle has previously been used with the legacy C2 over LTE app (earlier than v0.1.0), you must perform a one-time re-authentication.
{% endhint %}

<figure><img src="https://3329189600-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FFW1Ge1p1f6WHyiYCb146%2Fuploads%2FgXsYxhqXxIxxinjm4mxQ%2Fc2-legacy-video.gif?alt=media&#x26;token=6940db31-79cf-4190-851d-d6cff06c32d5" alt=""><figcaption></figcaption></figure>

1. In a browser, go to <http://10.41.1.1/apps>.
2. Make sure the legacy **C2 over LTE** app is removed.
3. Click the cogwheel icon on the new **BeyondLine** app and select **Settings**.
4. Set **Force Reauth** from `false` to `true` and click **Save**.
5. The app will then re-authenticate with Auterion Suite and register automatically. In the logs this will appear similar as:

```
com.auterion.beyondline.vpn | Attempting to fetch authentication key...
com.auterion.beyondline.vpn | Successfully fetched a valid authentication key.
com.auterion.beyondline.vpn | Attempting to configure connection with provided AUTH_KEY...
com.auterion.beyondline.vpn | Connection configured successfully with AUTH_KEY.
```

5. After the registration is complete, set **Force Reauth** back to `false` and click **Save** again.
