What is DJI AirSense?
Installing an ADS‑B transmitter on all new drones from DJI.
Starting January 1, 2020, DJI will equip all new drones over 250 grams with Automatic Dependent Surveillance-Broadcast (ADS‑B) receivers. According to the report, such a measure will significantly improve the safety of drone flights in the general airspace.
ADS‑B is a satellite air traffic surveillance system. It includes a GPS receiver that determines the location of the aircraft and the parameters of its flight, as well as a set of transceivers. The latter broadcast data on the flight parameters of an aircraft or helicopter to a network of ground stations and special satellites, which already transmit them to air traffic control services and other aircraft.
In addition, ADS‑B also receives information about the weather along the aircraft’s flight route. Currently, many airlines are equipping aircraft with ADS‑B transceivers. From January 1, 2020, for example, all aircraft flying to the United States must be equipped with such transmitters.
The ADS‑B signal receiver for DJI drones is called AirSense. According to the description of the developers, this device receives signals from aircraft within reach. In the event that the flight path of the drone intersects with the flight path of the aircraft, AirSense will notify the drone operator.
Whether the system is able to independently steer the drone away from a collision and whether its warnings can be ignored is not specified. Other details about the operation of the system are also not disclosed. Currently, only two types of DJI drones are equipped with ADS‑B receivers: the Matrice 200 and the corporate Mavic 2 Enterprise and Mavic 2 Enterprise Dual.
