HolyBro H-RTK F9P Ultralight — RTK GNSS Module, u-blox ZED-F9P, IST8310 Compass, Integrated Helical Antenna, 21.4g, 1cm RTK Accuracy, for Pixhawk Series & UAV Autopilots
The HolyBro H-RTK F9P Ultralight is a professional-grade, ultra-lightweight RTK GNSS module built around the u-blox ZED-F9P high-precision positioning engine. Designed specifically for weight-sensitive UAV applications, it integrates an IST8310 compass and a helical antenna in a single compact package weighing just 21.4 grams. Capable of tracking all four major GNSS constellations simultaneously — GPS, GLONASS, Galileo, and BDS — it delivers centimeter-level RTK accuracy (1cm+1ppm) when paired with correction data, making it ideal for precision mapping, inspection, and autonomous UAV operations.
Key Features
- u-blox ZED-F9P GNSS Engine — Industry-leading multi-band RTK positioning chipset with proven reliability in professional UAV deployments
- 1cm+1ppm RTK Accuracy — Horizontal centimeter-level accuracy for precision navigation, mapping, and autonomous missions
- Concurrent Multi-Constellation — Simultaneous GPS L1C/A L2C, GLONASS G1/G2, Galileo E1/E5b, BDS B1I/B2I, QZSS, and SBAS reception
- Ultra-Lightweight at 21.4g — Optimized for weight-critical aircraft where every gram impacts flight time and payload capacity
- Integrated Helical Antenna — High-performance, compact helical antenna built in for minimal installation complexity
- IST8310 Compass — Integrated 3-axis magnetometer for precise heading reference
- Dual UART Interface — UART1 for GNSS data output; UART2 dedicated for RTCM3 correction input
- I2C Interface — For compass data output to autopilot
- 10Hz Navigation Update Rate — High-frequency position updates for responsive autopilot control (higher rates available on request)
- Plug-and-Play with Pixhawk Series — Compatible with Pixhawk 4, 5X, 6X, Cube, and all ArduPilot/PX4-based autopilots via standard GH connectors
- Interference Suppression — Reliable positioning even in difficult RF environments
