Control and plan missions with this Remote Controller for Phantom 4 RTK from DJI. This controller utilizes the DJI OcuSync transmission system to receive an HD-quality image and video feed from the Phantom 4 RTK from up to 4.4 miles away. At those distances, you can pilot around and map large locations, or multiple locations from a single fixed point. By adding your smartphone or tablet to the built-in mount, the controller becomes an all-in-one solution, giving you access to the drone feed, telemetry data, and GS RTK app. Use the app to manually pilot or plan customized photogrammetry and waypoint flight plans.
