Overview

The DroneCAN H-RTK F9P (NXP S32K1) is the latest differential high-precision GNSS positioning system from Holybro. It has adopted the DroneCAN protocol for communication. It provides multi-band RTK with fast convergence times and reliable performance, concurrent reception of GPS, GLONASS, Galileo and BeiDou, and a fast update rate for highly dynamic and high volume applications with centimeter-accuracy. 

With the adoption of the DroneCAN Protocol, it has up to an 8 Hz navigation update rate, upgradeability, noise immunity, real-time features, and is more robust than UART due to its increased resistance to electromagnetic interference. It does not occupy any serial port of the flight controller, and multiple CAN devices can be connected to the same CAN bus via a hub.

This S32K1 Based DroneCAN-F9P uses a u-blox F9P module, a BMM150 compass, and a tri-colored LED indicator, and is equipped with the NXP S32K14 processor with 1MB Flash and 128 KB RAM. It is compatible with the open source Pixhawk series flight controller with both PX4 and Ardupilot. This S32K1 version uses PX4 CAN Node Firmware, and supports PX4 Dronecan Firmware Updating.

Note: This version does not support Dual GPS or GPS heading at this moment. We are working to get this supported as soon as possible. 

Features

DroneCAN F9P Rover The Rover model has a flatter profile and stronger water resistance. It uses a dual band patch antenna and comes with an integrated cable to connect to the CAN bus. It excels in spaces where there are few obstructions. You can find purchase link for this product here

DroneCAN F9P Helical This model uses a helical antenna, which has slightly better performance in space with obstructions than the Rover version. The antenna of this module can either be attached to the module directly or connected via a SMA cable, giving you the ultimate flexibility. It also has a UART2 port exposed, allowing you to do YAW/Heading (aka moving baseline). You can find the purchase link of this product here
