Holybro H-RTK F9P Base Station

The Holybro H-RTK F9P Base is a precision dual-frequency RTK GNSS base station built around the u-blox ZED-F9P multi-band receiver, delivering centimetre-level positioning accuracy for survey-grade mapping, precision agriculture and autonomous navigation applications. Designed to work with Holybro H-RTK rover modules and ArduPilot or PX4 autopilots, it supports GPS, GLONASS, Galileo, BeiDou and QZSS constellations across L1/L2 bands for fast RTK convergence and robust correction streams.

Key features

• u-blox ZED-F9P chipset: dual-frequency multi-constellation receiver with integrated RTK engine for horizontal accuracy down to 0.01 m + 1 ppm CEP

• Survey-in and fixed modes: auto-calibrates position for temporary deployments or accepts known coordinates for permanent installations

• RTCM 3.x correction output: streams differential corrections via serial, USB or telemetry link to compatible rover units

• IP67 weather protection: sealed housing and connectors for outdoor field operation in rain, dust and temperature extremes

• Wide input voltage range: powered from 5–28 V DC for battery or mains integration

Use this base alongside a compatible rover module to eliminate GNSS drift during long autonomous missions, achieve repeatable waypoint accuracy for agricultural spraying, or capture survey-quality photogrammetry datasets. The unit requires clear sky view and benefits from a ground plane for optimal multipath rejection.
