D-RTK 3 Multifunctional Station is DJI’s latest high-precision positioning and relay system that integrates high-performance antennas and receiver modules tracking major global satellite navigation systems across 19 frequency points. This versatile station operates in three modes: Base Station Mode providing centimeter-level RTK positioning for multiple drones simultaneously with 40 km coverage, Relay Station Mode extending drone operational range up to 25 km in obstructed environments, and Rover Station Mode for ground control point collection with tilt compensation. Featuring millimeter-level antenna phase-center accuracy, air dielectric antenna with multipath interference resistance, Standalone PPP for decimeter-level positioning, and Network High-Precision Calibration, the D-RTK 3 ensures reliable positioning in challenging conditions. Compatible with DJI Enterprise app for GCP setup, projection coordinate conversion, and seamless DJI Terra integration supporting local PPK processing.
