When using your Phantom 4 RTK or MG-1P RTK drone to map or survey a jobsite, you can help your accuracy with the DJI D-RTK 2 GNSS Mobile Station and Tripod Kit from B&H. This kit is designed to augment your drone's mapping accuracy by giving you a strong and stable GNSS network signal. With a steady signal your RTK drone can achieve centimeter-level mapping accuracy. Simply place the mobile station on the site where you get the best signal. The mobile station supports access to GPS, GLONASS, Beidou, and GALILEO GNSS networks.
