Holybro DroneCAN H-RTK F9P Rover GNSS Module (42cm)

The Holybro DroneCAN H-RTK F9P Rover is a high-precision GNSS receiver built for professional ArduPilot and PX4 applications, including heavy-lift multirotors, agricultural drones, and autonomous ground vehicles. By transitioning from traditional UART to the robust DroneCAN protocol, this module ensures fault-tolerant, high-speed data transmission while dramatically reducing EMI susceptibility. Powered by the industry-standard ZED-F9P chipset, it delivers rapid satellite acquisition and stable centimetre-level RTK positioning.

Key features

• Powered by the multi-band u-blox ZED-F9P module for concurrent reception of GPS, GLONASS, Galileo, and BeiDou
• DroneCAN protocol (1Mbit/s) provides superior noise immunity and allows simple daisy-chaining with other CAN peripherals
• Delivers centimetre-level navigation accuracy when paired with a fixed RTK base station
• Integrated magnetometer for reliable yaw alignment in complex magnetic environments
• Includes a 42cm cable configuration, ideal for routing through larger commercial airframes or rover chassis
