CubePilot Here4 Blue Multiband RTK GNSS with NRF 2.4GHz Radio

Description

Product Description
The Here4 Blue is a professional-grade multiband RTK GNSS navigation module offering centimeter-level accuracy with exceptional reliability and performance. Equipped with the powerful u-blox F9P dual-band GNSS receiver and a custom high-gain L1/L5 Taoglas antenna, the Here4 Blue delivers fast RTK Fix acquisition and stable positioning even in challenging conditions. It supports a wide range of satellite systems including GPS, GLONASS, BeiDou, Galileo, SBAS, and QZSS.

But the Here4 is more than just a GNSS module. With built-in DroneCAN support, IMU, barometer, hot-shoe and camera trigger, RC input, and up to 8 PWM/BDSHOT outputs, it serves as a compact, self-contained flight and navigation controller for UAVs and mapping platforms.

The Here4 Blue features both NRF 2.4GHz radioand Bluetooth 5.2support. The NRF 2.4GHz module enables DroneCAN telemetry and Drone-ID broadcasting, typically used for real-time UAV identification or telemetry data in closed systems. Meanwhile, Bluetooth 5.2enables wireless configuration, data access, or potential firmware updatesvia compatible BLE devices.

Designed for high-performance applications requiring accuracy and modular integration, the Here4 Blue is the ideal RTK solution for commercial UAV platforms, research applications, and industrial automation.
