Here4 Blue Multiband RTK GNSS with Bluetooth 5.2

Here4 Blue Multiband RTK GNSS with Bluetooth 5.2

The Here4 Blue is a professional-grade, high-precision dual-band RTK navigation module designed for mission-critical UAV applications. Unlike the standard Here4, the “Blue” version is Manufactured in the USA and is NDAA 2023 compliant, making it suitable for government and defense projects. It is powered by the u-blox NEO-F9P engine, delivering centimeter-level accuracy with the fastest lock times in the Here series. Beyond simple GPS positioning, the Here4 Blue acts as a localized flight controller and navigation hub, featuring integrated IMUs, a barometer, and Bluetooth 5.2 specifically for Remote ID compliance.

Features

• Centimeter-Level Accuracy: Utilizes the u-blox NEO-F9P L1/L5 multiband RTK module for reliable, high-precision positioning.

• Bluetooth 5.2 for Remote ID: Fully supports integrated Drone ID requirements, ensuring compliance with modern airspace regulations.

• Dual-Core Processing: Built-in STM32H757 processor handles real-time data optimization and on-board flight control tasks.

• Integrated Sensing: Equipped with the RM3100 magnetic compass and ICM42688 sensors for superior orientation and stability.

• Multi-Functional Module: Includes 8 PWM/BDSHOT outputs and a camera trigger, allowing it to function as a self-contained mapping controller.

• DroneCAN FD Protocol: Uses high-speed (8Mbps) communication for stable and rapid data transmission to the main flight controller.

Key Points

• US Manufacturing: Specifically built in the USA to meet strict security and procurement standards (NDAA compliant).

• Rapid Convergence: Achieves an RTK Fix in under 10 seconds thanks to advanced multi-frequency DGNSS algorithms.

• High Performance Antenna: Features a custom Taoglas dual-band antenna for high gain and sensitivity in challenging environments.

• Expandable Platform: Based on the open-source AP-Periph platform, allowing for extensive user customization and firmware updates.
