Botlink XRD2

The Botlink XRD2 is UAS command and control hardware and software solution, allowing drone control from anywhere in the world via cellular networks. An enabling technology for safe beyond visual line of sight (BVLOS) flights, the XRD2 uses carrier-approved LTE components for airborne operations. The Botlink XRD2 system consists of two components — a PC connection application, and a small hardware device that’s connected to the drone autopilot, making integration simple and effective with the ability to read live data, track telemetry, and control multiple UAVs, the XRD2 is ideal for managing large drone fleets. The flight-proven XRD2 system allows you to easily integrate LTE command and control in the same nature as traditional point-to-point radios.

Proprietary network architecture designed to reduce command and control and payload latency and reliability.

Specifically designed to support MAVLink based drones, including copters, fixed-wing, and VTOL.

All data is encrypted, and XRD device is NDAA Section 889 certified. Hardware and software US developed and assembled.

Easily integrate with QGroundControl, Mission Planner, or custom GCS with available SDK.

  • Includes 1080p camera and supports out-of-the-box video streaming over LTE network

  • USB connectivity for autopilot, cameras, and peripherals

  • Easily updated via USB-C port

  • All data processed by XRD2 is encrypted from end-to-end using 128 or 256-bit TLS

  • Built-in authentication for enhanced security

  • All communication data is routed through AWS servers based in USA

  • Compatible with MAVLink autopilots such as the Pixhawk, Pixhawk 2, and ArduPilot Mega, running PX4 or APM firmware

  • Fully compliant with Section 889 of the National Defense Authorization Act

  • Dedicated UAS support team based in Fargo, ND

The XRD2 has been shipped to customers around the world, and flown on dozens of different cellular networks. Every decision made during the design of the second-generation XRD2 was to make it as simple and reliable to use as possible.

Relay Features

Botlink Relay is an app that runs on your Windows or Mac computer that handles the process of connecting to your drone using the Botlink system. Once Botlink Relay is running, connecting to a drone is as simple as launching the ground control software.

Available Botlink Relay SDK makes integrating cellular connectivity directly into your custom flight control software quick and easy.

  • Default Port settings are automatically connected to QGroundControl or Mission Planner

  • Easily connects to QGroundControl or Mission Planner

  • Custom SDK available for custom integration

  • Live video feed from drone displayed in Relay

  • Control video feed quality directly from interface

  • Intelligent graphs return real-time communication statistics and health reports

  • Can connect multiple Botlink Relays to a single XRD, ideal for video broadcasting

  • Download the most recent version of Relay

All communication between the XRD2, cloud services, and Relay App/SDK are encrypted using 128 or 256-bit TLS, and all connections are authenticated. These requirements are enforced by the Botlink cloud services, which operate as a bridge for all connections between XRD2s and clients, ensuring that no unauthorized parties are able to connect to drones over the cellular network. Each XRD2 is registered to a specific organization, and only users in that organization are allowed to connect to and control a drone using that XRD2. The Botlink system does not store the contents of the C2 data that passes through the system. It is simply passed from one end of the authorized connection to the other.


Optional Video Camera

Botlink’s included high-definition camera takes the guesswork out of video-streaming over a cellular network. Out-of-the-box compatibility means less time integrating, and more time streaming live video during operations.

The XRD’s processor allows for H265 video encoding, including video downsampling to 480p at 5 FPS allows users to choose the minimal video quality necessary for flight while minimizing the data transmission rates.
