When trying to create aerial maps with centimeter-level precision, the D-RTK 2 High-Precision GNSS Mobile Station from DJI can be used to deliver real-time differential corrections by directly accessing 11-frequency satellite reception for all major GNSS constellations: GPS, Galileo, GLONASS, and BeiDou. The RTK base station can also be instrumental when trying to conduct coordinated mapping operations with multiple drones. As the mobile station is designed for outdoor use, DJI created it with a robust IP65-rated level of water and dust resistance.
