RTK GNSS Receiver for Drones & UAVs — Centimetre Accuracy for Aerial Operations
High-precision RTK GNSS for drone mapping, inspection, LiDAR, and autonomous UAV operations. Septentrio-powered receivers with AIM+ anti-jamming deliver reliable positioning even in RF-congested airspace.
Precision GNSS for Professional Drone Operations
Modern UAV operations demand centimetre-level positioning accuracy for photogrammetry, LiDAR mapping, inspection, and autonomous navigation. Standard GPS-only receivers provide 2-5 metre accuracy — insufficient for precision drone workflows. RTK GNSS receivers deliver sub-centimetre accuracy by using real-time correction data from a base station or network.
Eview GNSS offers a complete range of RTK solutions for drones: lightweight OEM boards for direct integration into UAV payloads, smart antennas for drone ground stations, and GNSS receiver boxes for base station deployments. All powered by Septentrio technology with AIM+ anti-jamming to maintain lock in challenging RF environments.
Why 100 Hz Native GNSS Matters for Your Drone
Most GNSS receivers in drones use IMU interpolation between position fixes — guessing where the drone is between GPS updates. Septentrio’s 100 Hz native GNSS delivers a genuine satellite position every 10 milliseconds, giving your drone true real-time control with no drift accumulation.
Genuine GNSS Every 10 ms
Not IMU-interpolated guesswork. Every position frame is computed directly from satellite measurements — acquisition, tracking, and positioning — in each 10 ms cycle. Your drone’s flight controller gets real data, not synthesized estimates.
No Drift Accumulation
IMU-based systems accumulate error over time — bias, temperature drift, and vibration coupling degrade accuracy. Pure GNSS architecture means each position is independent. No drift. No sensor compensation errors. Just reliable positioning frame after frame.
Ultra-Low Latency for Flight Control
Predictable <10 ms latency with minimal jitter means tighter control loops and simpler PID tuning. For high-speed drone maneuvers, the difference between 5 ms and 20 ms latency is the difference between stable flight and oscillation.
vs u-blox F9P Interpolated
u-blox F9P delivers 10-20 Hz with IMU blending — only ~10% genuine GNSS updates. Septentrio delivers 100 Hz native: 10x the genuine position updates for more responsive drone control, especially critical in BVLOS and autonomous operations.
Key Takeaway: While competitors advertise 200 Hz update rates, those are IMU-interpolated between actual GNSS fixes — susceptible to drift. Every one of Eview’s 100 Hz position frames is a genuine satellite measurement. For autonomous drone operations, BVLOS flights, and precision inspection, this means positioning you can trust without degradation over time.

Drone GNSS — Frequently Asked Questions
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.
