The range of UAV operations is limited by the availability of a reliable command and control (C2) link. By leveraging Viasat’s Velaris network, Gotonomi’s range of lightweight satellite communication (satcom) terminals offer nearly global connectivity for UAVs. This allows UAV operators to extend the reach of their Ardupilot systems, unlocking new possibilities for Beyond Visual Line of Sight (BVLOS) operations, such as long-range surveillance and remote-area inspections.

Ardupilot has transformed the UAV industry, evolving from a hobbyist tool into a reliable autopilot system used globally by professional operators, research institutions, and industry leaders. It provides advanced flight control capabilities for a range of UAV platforms, including multicopters, helicopters, and fixed-wing aircraft. However, UAV operations still face range limitations due to reliance on line-of-sight short-range radio or consumer cellular networks, which do not meet the safety standards required for BVLOS operations. This presents a significant challenge for long-range applications.

Expanding Ardupilot’s Reach with Satellite Connectivity
Recent advancements in satcom terminals for UAV applications now make it possible for operators to gain global connectivity. Gotonomi’s Velaris terminals, engineered for smaller airframes, are an ideal solution for extending the range and reliability of UAVs.
To help UAV operators seamlessly integrate Gotonomi’s Velaris terminals with Ardupilot, Gotonomi has created a straightforward “how to” guide for the process.
Components for Simple Integration:
- Velaris Terminal – Any of the Gotonomi terminals – V200, Velaris Module, or the LTE enabled Multilink Module.
- Pixhawk 6C Flight Controller – A popular open-source UAV flight controller.
- Ardupilot Firmware with Networking Capabilities – Custom firmware can be built with networking options using Ardupilot’s build server.
- Raspberry Pi – UART (Universal Asynchronous Receiver/Transmitter) interface with Pixhawk flight controller establishing a Point-to-Point Protocol (PPP) link. Uses ethernet to connect to Velaris terminal.
- Telemetry Forwarding via MAVProxy – Telemetry data from the Pixhawk flight controller is forwarded through MAVProxy on the Raspberry Pi, ensuring continuous communication between the UAV and ground control stations. This setup ensures uninterrupted command and control through the Viasat Velaris satellite network.
Integration Process
To integrate the Pixhawk 6C with Ardupilot’s custom firmware and the Velaris terminal via the Raspberry Pi, involves establishing a serial link from the Pixhawk with custom Ardupilot firmware to the Raspberry Pi via UART (TELEM1). The Raspberry Pi then connects to the Velaris terminal through Ethernet. Together, this subnetwork communicates directly with Viasat’s network. This configuration enables a secure, reliable communication channel between the UAV and ground stations, via satellite.
With the integration complete, UAV operators gain access to instant plug-and-play connectivity, powered by Gotonomi’s Velaris terminals and Ardupilot’s user interface. Gotonomi’s satcom solution simplifies and enhances the operational potential of Ardupilot, enabling a wider range of UAV applications.
Unlocking Advanced BVLOS Applications
With reliable telemetry and C2 link via satellite, operators can scale their BVLOS operations with confidence. This expanded capability unlocks numerous advanced applications, including remote surveillance, environmental monitoring, inspection of critical infrastructure, and emergency response operations.
