Found in numerous types of drones, dual Global Navigation Satellite Systems (GNSS) like GPS and GLONASS drones are able to operate in both non-satellite and satellite modes, providing enhanced connectivity during operation
GNSS allows Return to Home safety technology to function on a drone and can be activated through the ground station's remote controller. This allows pilots to be informed as to whether there are enough drone GNSS satellites available for the drone to be flown independently, the current location of the drone compared to the pilot and the "home point" for the drone to return to. In addition to being controllable through the controller, Return to Home can also be automatically activated once the battery is low or when loss of contact between the drone and the controller occurs.
