DJI Phantom 4 RTK: Precision Aerial Mapping Drone
DJI Phantom 4 RTK Quadcopter Overview
The Phantom 4 RTK is a specialized version of DJI’s Phantom 4 drone designed for ultra-precise mapping with centimeter-level accuracy, making it ideal for surveying, construction, and inspection work. It achieves this high accuracy through an integrated RTK (Real-Time Kinematic) receiver mounted on top, delivering positioning precision of 1cm + 1ppm horizontally and 1.5cm + 1ppm vertically.
Precision Positioning and Calibration:
DJI’s TimeSync system continuously aligns the flight controller, camera, and RTK module to ensure metadata accuracy.
Each camera’s unique lens distortions (radial and tangential) are measured and included in image metadata for precise post-processing.
Supports real-time mapping via the GS RTK app with Photogrammetry and Waypoint Flight modes, enabling flight path planning and direct import of KML files.
Achieves about 5cm absolute horizontal accuracy in photogrammetric models under ideal conditions (100m altitude, 2.7cm GSD).
RTK data can connect to D-RTK2 Mobile Station, NTRIP networks, or be used in post-processing kinematics (PPK).
Advanced Camera System:
Features a 1-inch, 20MP CMOS sensor—significantly larger than the standard Phantom 4’s sensor—delivering better image quality, dynamic range, and low-light performance.
Equipped with a mechanical shutter eliminating rolling shutter distortion, allowing crisp images of fast-moving subjects.
The lens consists of eight elements (including two aspherical) arranged in seven groups, offering sharp images with minimal distortion.
Supports cinema-grade 4K video recording at 60 fps (H.264) or 30 fps (H.265), both at 100 Mbps, enabling high-quality video for post-production.
Remote Controller and Transmission:
Comes with a controller featuring DJI’s OcuSync transmission, offering HD video streaming up to 4.3 miles.
Supports dual-frequency (2.4 GHz and 5.8 GHz) Lightbridge HD video link with automatic frequency switching to reduce interference and image lag.
Transmission system uses Time Division Multiplexing (TDM) for reliable controller commands and video streaming on the same frequency.
Intelligent Flight Modes:
Draw Mode: Draw flight paths onscreen with options for constant speed or free control.
ActiveTrack: Automatically recognizes and tracks subjects like people, vehicles, or animals with several tracking styles (Trace, Profile, Spotlight).
TapFly: Tap the screen to direct flight with options for forward, backward, or free directional control, plus obstacle avoidance (except in TapFly Free).
Return to Home: Automatically finds the safest path back, avoiding obstacles and checking for safe landing zones based on previously recorded flight data.
Gesture Mode: Capture selfies using simple hand gestures without a controller.
Flight and Safety Features:
Multiple flight modes (Position, Sport, Attitude, Tripod) provide different levels of control and agility.
Dual compass and dual IMU sensors ensure flight stability and redundancy by cross-verifying sensor data.
Maximum flight time is approximately 30 minutes, with an intelligent battery system monitoring power and maintaining battery health.
Enterprise Shield Basic Protection Plan:
DJI offers a protection plan covering accidental damage like pilot error, collisions, signal interference, water, and drops.
The plan allows up to two replacements per year with fees of $299 for the first and $399 for the second replacement.
Coverage excludes the Zenmuse X4S, X5S, or Z30 gimbals, which require separate plans.
