Operator Control

The Operator Control (also known as RC or Remote Control) allows the operator to control and monitor all aspects of the drone and its operation. This includes piloting, interacting with the attached camera and its gimbal, and building and tracking missions. All while providing the necessary information to ensure a safe and controlled flight, such as drone telemetry, camera’s video feed, environmental information, and more. This can be done with a local drone within the control’s radio link range, or with a drone anywhere in the world, as long as both the drone and the controller have access to the internet. The picture below shows the front view of the Operator Control, which is composed by a touch screen, two joysticks for piloting the drone, a wheel, and six buttons.

The main interfaces can be described as:

  • Directional and omnidirectional antennae: Antennae that establish the wireless connection between the Operator Control and the drone;

  • Left joystick (up/down): Drone’s throttle control;

  • Left joystick (left/right): Drone’s yaw control;

  • Right joystick (up/down): Move the drone forwards/backwards;

  • Right joystick (left/right): Move the drone sideways;

  • Main screen: Displays information for the user and provides additional actions (see next sections for further details);

  • Button A: Cine mode;

  • Button B: Position mode;

  • Power switch: Switches the device on/off;

  • Home: Commands the drone to land immediately;

  • Button C: Open and closes the drone’s landing gear;

  • Button D: RTL (Return To Land) command;

  • Gimbal wheel: Controls the primary gimbal’s pitch movement;
