RTK GNSS Receiver for Drones & UAVs — Centimetre Accuracy for Aerial Operations

RTK GNSS provides 1-2 cm horizontal accuracy at the drone level. For photogrammetry, this translates to 1-2 cm ground sampling distance (GSD) at 100 m altitude, eliminating the need for ground control points in most mapping projects.

RTK (Real-Time Kinematic) provides real-time centimetre corrections via radio or NTRIP link during flight. PPK (Post-Processed Kinematic) logs raw data and processes after landing. RTK is ideal for real-time applications and BVLOS. PPK is preferred when a reliable correction link cannot be maintained, as it avoids the risk of RTK fix loss mid-flight.

Yes. Eview GNSS receivers output RTCM 3.x correction data compatible with DJI RTK modules (D-RTK 2, Zenmuse P1, L1) via NTRIP. For third-party drones, our OEM boards support MAVLink and direct UART/SPI integration with Pixhawk, CUAV, and other open-source flight controllers.

Septentrio mosaic-X5 OEM boards weigh approximately 50 g including shielding, making them suitable for lightweight drone payloads. The board dimensions are 71 x 47 x 17 mm, designed for integration into compact UAV airframes.

Drones operate near RF interference sources including power lines, cell towers, and radio transmitters. AIM+ anti-jamming suppresses interference up to 60 dB, maintaining RTK lock and preventing fly-away or loss of navigation in urban or industrial environments where standard GNSS receivers would fail.

With a 1 W radio modem and clear line of sight, RTK corrections can be transmitted up to 20 km. Using NTRIP over 4G/LTE, coverage extends as far as the cellular network. For missions beyond radio range, PPK mode logs raw data for post-processing and has no range limitation.
