Sky Drone Link

Sky Drone Link

  • $999.00 USD

Sky Drone Link is a transmission system for drones that transmits HD video from any HDMI connected camera over the LTE network, providing an unlimited range and low latency video+data link.


Digital High Definition Video

Sky Drone Link supports HDMI camera input with 1080p up to 60fps.

Gimbal Control / Flight Controller Link

Besides the video link, Sky Drone Link provides a bidirectional data link between your drone and your Ground Control Station. This can be used to visualized telemetry data and/or control the drone. We support the MAVLink protocol as well as any generic protocol that interfaces via RS232/UART. Many gimbals can be controlled over a serial RS232/UART interface and Sky Drone Link can act as a virtual serial cable. This functionality is entirely optional.

Unlimited Range

By using existing cellular networks, the Sky Drone Link system provides you with virtually unlimited range. The only requirement is cell tower coverage. The system is optimized for the 4G/LTE network to provide best video quality and lowest latency. It does however fall back to 3G or even 2.5G networks by automatically adjusting video parameters without interrupting the stream.


Low latency

By using our own highly optimized video processing pipeline, the system is designed for lowest latency video from scratch. The typical end-to-end latency is less than 350ms depending on the camera used.


Groundstation Software

The Groundstation to receive Video from the Sky Drone Link unit runs on Windows and Linux with version for MacOS, Android and iOS in the pipeline to be released in Q4 2017.


The video stream and meta data are fully end-to-end encrypted making it impossible for third parties to eavesdrop the transmission or interfere with it. Rather than reinventing the wheel, we rely on open and proven standards including Datagram Transport Layer Security (DTLS) and Secure Real-Time Protocol (SRTP) using AES128.

How it works
