Herelink Overview

Overview

Herelink is an integrated remote controller, ground station and wireless digital transmission system designed to be used with the Cube Autopilot, Ardupilot or PX4.

Herelink allows RC control, HD video and telemetry data to be transmitted upto 20km between the ground station and air unit, the Herelink remote controller features custom Solex TX and QGC applications and both air unit and ground station feature an integrated 8 core SOC for custom application development.

Features

  • Android based smart device with 5.46 inch 1080P capacitive touch screen.

  • Integrated digital transmission system simultaneously transmitting video, telemetry and control.

  • Custom Solex TX and QGC ground station software with MAVlink support for Ardupilot and PX4.

  • Dual hall effect self centering gimbals with removable sticks.

  • 1080P HD video with dual digital video inputs.

  • Dual S.bus signal output for simultaneous control of autopilot and pan/tilt cameras.

  • 6 customisable Mavlink buttons and Mavlink/Sbus hardware wheel.

  • RC gimbal control on dedicated service independent from Solex TX / QGC.

  • Tether and share video and telemetry via wifi ground station such as Mission Planner.

  • Onboard Arm Cortex A53 & Cortex A53 SOC in both air and ground units for custom applications.
