Here4 Blue Multiband RTK GNSS with NRF 2.4GHz Radio

Here4 Blue Multiband RTK GNSS with NRF 2.4GHz Radio

Product Description

The CubePilot Here4 Blue Multiband RTK GNSS is a professional-grade navigation solution that redefines precision and versatility for the modern UAV industry. Powered by the advanced u-blox F9P dual-band receiver and a custom high-gain Taoglas L1/L5 antenna, the Here4 Blue delivers rapid RTK fix times and centimeter-level positioning accuracy, even in challenging RF environments. It supports comprehensive satellite constellations including GPS, GLONASS, BeiDou, Galileo, and QZSS, ensuring your sUAS maintains a rock-solid lock wherever your mission takes you.

More than just a GPS, the Here4 Blue acts as a compact, self-contained avionics hub. Built on the powerful STM32H757 processor running AP_Periph firmware, it integrates an industrial-grade IMU (ICM42688 + RM3100) and barometer, allowing it to function as a standalone flight controller or a highly capable peripheral. It features extensive I/O capabilities, including 8 PWM/BDSHOT outputs, RC input, and dedicated hot-shoe camera triggering, making it ideal for aerial mapping and photogrammetry workflows.

Uniquely, the Here4 Blue is equipped with both an NRF 2.4GHz radio and Bluetooth 5.2. The NRF module enables robust DroneCAN telemetry and support for Drone-ID broadcasting, a critical feature for compliance and real-time identification in commercial and government operations. The Bluetooth 5.2 connectivity facilitates wireless configuration and health monitoring via compatible devices, streamlining your pre-flight checks.

Key Features:

• Dual-Band RTK Precision: Utilizes the u-blox F9P module for centimeter-level accuracy (0.01m + 1ppm CEP) and sub-10 second convergence.

• Multi-Role Capability: Functions as a GNSS, a DroneCAN peripheral, or a standalone flight controller with its built-in STM32H7 processor.

• Wireless Connectivity: Features NRF 2.4GHz for Drone-ID/telemetry and Bluetooth 5.2 for wireless updates and settings.

• Advanced Sensors: Integrated ICM42688 Accelerometer/Gyro, RM3100 Compass, and MS5611 Barometer for superior flight stabilization.

• Mapping Ready: Dedicated hot-shoe and camera trigger support for precise geotagging.

• Robust Data Link: Supports DroneCAN FD (CAN Flexible Data-Rate) at 8Mbit/s for high-speed, reliable communication with the autopilot.
