Product Overview:

The Here 4 is a high-precision, dual-band RTK navigation module, designed for professional use. It supports multiple global navigation satellite systems (GNSS) such as BeiDou, Galileo, GLONASS, GPS, and QZSS, providing reliable centimeter-level accuracy. Utilizing advanced algorithms and multi-frequency DGNSS signals, the Here 4 achieves an RTK fix in seconds, offering exceptional precision and stability.

More than just a GNSS module, the Here 4 integrates flight control and navigation functionalities into one compact device. With 8 PWM or BDSHOT outputs, RCIN, hotshoe, and camera trigger, it offers a complete solution for both accurate mapping and precise control operations.

Key Features:

  1. u-blox F9P Dual-band RTK Navigation Module: Delivers high-precision, dual-band GNSS performance.

  2. Powerful Processing: Built-in STM32H7 chip ensures real-time data processing and optimization, running on the AP_Periph firmware standard used in the unmanned industry.

  3. High-performance Dual-band Antenna: Tailor-made by Taoglas, supporting L1 and L5 frequencies, offering high gain, sensitivity, and stability.

  4. Blue Version with Drone-ID Support: Adds compliance for Drone-ID.

  5. Fast RTK Fix: Multi-frequency DGNSS signals and advanced algorithms enable quick RTK convergence, achieving stable, centimeter-level accuracy.

  6. Compact & Lightweight: The module measures 16 x 68mm and weighs just 60g.

  7. ProfiLED Embedded Display: Built-in LED system with multiple display modes for notifications or navigation signals, customizable via parameters or onboard Lua scripting.

  8. High-Speed CAN FD Communication: Real-time data transmission with high bandwidth.

  9. Built-in IMU: With future firmware updates, the Here 4 will support tightly coupled DGNSS-INS-fused positioning solutions for enhanced precision.

  10. Integrated Flight Control & Navigation: The module offers more than just GNSS capabilities, with 8 PWM/BDSHOT outputs, RCIN, hotshoe, and camera trigger functionalities, making it a self-contained solution for accurate mapping and control.

  11. Expandable & Customizable: The DroneCAN FD communication protocol supports fast (8Mbps) and stable transmission, and the open-source AP-Periph platform allows for further development and customization.
