Here4 Blue Multiband RTK GNSS with NRF 2.4GHz Radio

The Here4 Blue is an enterprise-grade multiband RTK GNSS module built for heavy-lift platforms, autonomous agriculture drones, and professional survey rigs running ArduPilot or PX4. Designed for secure and highly precise positioning, it leverages a dual-core STM32H7 processor to manage high-speed DroneCAN communication and advanced routing.

Key features

• Multiband RTK precision: Integrated u-blox F9P receiver enables rapid convergence and centimetre-level accuracy using concurrent satellite constellations.

• Integrated 2.4GHz radio: Features an onboard nRF52840 module for localized mesh networking, wireless telemetry, and Remote ID integration.

• DroneCAN protocol: Eliminates UART bottlenecks with a robust CAN bus interface, ensuring reliable data transmission over long wire runs.

• Interference resistance: Includes the industry-standard RM3100 magnetic compass for precise heading estimation even in challenging magnetic environments.
