Holybro DroneCAN H-RTK F9P Helical Navigation Module

Product Overview: The Holybro DroneCAN H-RTK F9P Helical Navigation Module is designed for professional applications in unmanned systems, providing precise positional information thanks to the advanced u-blox F9P receiver. The module is developed to operate using the DroneCAN protocol and combines high data refresh rates, interference resistance, and flexible connectivity, making it an excellent choice for both aerial vehicles (rovers) and base stations.

Key Technical Specifications and Features: DroneCAN protocol support ensures navigation updates up to 8 Hz, enhanced resistance to noise and electromagnetic interference compared to traditional UART, and does not occupy any flight controller serial port, allowing multiple CAN devices to be connected to a single bus without conflicts. The module is equipped with a BMM150 compass and a tri-color LED indicator for system status indication.

Hardware Platform: At the core of the module is an advanced STM32G4 microcontroller, operating at 170 MHz, with 512 KB of flash memory and 96 KB of RAM. This provides sufficient computational resources for processing navigation data and interacting over the DroneCAN network. The module is compatible with open-source Pixhawk series flight controllers, simplifying integration into existing aviation platforms.

Helical Antenna and Connectivity Options: The Helical version uses a helical antenna, which demonstrates improved performance in noisy environments compared to the Rover version. The antenna can be connected directly to the module casing or via an SMA cable, offering maximum flexibility in antenna placement for optimal signal reception.

Interfaces and Functions: The module features an open UART2 port, which allows for YAW/Heading functions (also known as moving baseline), crucial for precise platform orientation. When used as an RTK base station, interaction with the ground control station is via USB, so the DroneCAN protocol is not applied in base station mode.

Firmware and Compatibility: The device supports DroneCAN firmware updates using the DroneCAN GUI tool, allowing the module to be kept up-to-date and providing additional functionality in the future. Thanks to compatibility with Pixhawk controllers, integration into most professional and amateur systems is quick and correct.

Who It's For: The Holybro DroneCAN H-RTK F9P Helical is suitable for engineers and UAV operators who require reliable RTK navigation with high interference resistance, flexible antenna connectivity, and the ability to operate both as a moving receiver (rover) and as a base station with USB connectivity.
