Why the D-RTK 3 changes the economics of survey
Traditional survey methodology requires the crew to place, mark and recover ground control points before and after every flight — a process that typically consumes two to four hours per survey site. The DJI D-RTK 3 base station eliminates this workflow entirely.
The D-RTK 3 operates in Base, Rover and Relay modes. In Base mode paired with the Matrice 4E's built-in RTK receiver, it establishes a real-time centimetre-level correction stream across the entire survey area. The Matrice 4E captures every image with its corrected position embedded directly in the EXIF metadata. No ground control points are required for most survey applications.
For survey projects that do require independent GCP verification — cadastral, infrastructure, mining — the Matrice 400 Survey Bundle includes four Propeller Aeropoints, which can be deployed in minutes and geo-referenced automatically.
Zenmuse L3: when the project demands LiDAR
Photogrammetry produces excellent results on open terrain with consistent texture. It struggles in dense canopy, on vertical surfaces and in environments with repetitive structure. LiDAR has no such limitation.
The Zenmuse L3's 1535nm laser achieves 950m range on 10% reflectivity targets — reaching the top of tall transmission towers, penetrating dense forest canopy to the ground, and mapping vertical cliff faces in a single pass. Dual 100MP RGB cameras produce colourised point clouds directly, eliminating the manual colouring step.
CFexpress Type B cards are the correct format for the L3 — standard microSD readers will not work. The bundle includes the additional PGYTECH CFexpress Type B reader for field data offload.
