DJI Phantom 4 RTK + D-RTK 2 Mobile Station Combo

The DJI Phantom 4 RTK (P4R) is a high-precision drone for surveying and mapping, and the D-RTK 2 Mobile Station is its compatible ground base station that provides centimeter-level positioning accuracy by receiving satellite signals and transmitting correction data to the drone via OcuSync, forming a complete RTK system for reliable, accurate flight and data collection, especially when set up over a known point or used with NTRIP services for industrial applications like agriculture or inspections. Phantom 4 RTK (Drone) Key Features: 1-inch, 20MP CMOS sensor, 4K video, mechanical shutter (eliminates rolling shutter blur), obstacle avoidance, long range (4.3 miles). Accuracy: Achieves high precision with RTK, capturing data for detailed mapping. D-RTK 2 Mobile Station (Base Station) Function: Acts as a ground reference station, providing Real-Time Kinematic (RTK) corrections to the P4R. Connectivity: Supports 4G, WiFi, LAN, and OcuSync, connecting to satellite constellations (GPS, GLONASS, Galileo, BeiDou) for robust signal reception. Durability: Rugged design (IP65) for industrial use. Workflow: Can be set up as a base over a known point or used as a rover to gather precise coordinates, supporting both RTK and PPK workflows. How They Work Together Setup: The D-RTK 2 is set up in the field (ideally over a known point), while the P4R controller connects to it. Data Correction: The base station sends correction data to the drone in real-time, allowing the P4R to know its exact position to within centimeters. Mission Execution: Used with flight planning apps (like DJI GS RTK), the system executes missions with highly accurate geotagged images. Why Use Them Together? Survey-Grade Accuracy: Essential for mapping, inspection, and agriculture where precise location data is critical. Reliability: Offers consistent performance and can be used in various conditions, outperforming NTRIP in some scenarios due to direct connection.
