This External GPS Kit for the DJI Matrice 200 Series V2 provides you with an external GPS antenna which is required when top-mounting a gimbal on the M210 V2 or M210 RTK V2. Some third-party sensors and accessories also utilize the External GPS Kit and the manufacturer of your sensor or accessory should specify when to use it. The GPS antenna is built onto a landing gear mounting bracket that can replace either the left or right-hand mounting bracket already on your aircraft.
