HEX/ProfiCNC Here2 GPS (Discontinued)


This has been superseded by the Cube Here 3

The Here2 GPS receiver is an update to the Here GPS module from HEX.

Main features include:

  • Concurrent reception of up to 3 GNSS (GPS, Galileo, GLOSNASS, BeiDou)
  • Industry Leading -167 dBm navigation sensitivity
  • Security and integrity protection
  • Supports all satellite augmentation systems
  • Advanced jamming and spoofing detection

Where to Buy


Setup and use on PX4 is largely plug and play.



The Here2 GPS comes with an 8 pin connector that can be inserted directly into the Pixhawk 2 GPS UART port.

The Pixhawk 3 Pro and Pixracer have a 6 pin GPS port connector. For these controllers you can modify the GPS cable (as shown below) to remove pin 6 and 7.

Pin 6 and 7 are for the safety button - these can be attached as well if needed.


The Here2 GPS pinout is provided below. This can be used to help modify the connector for other autopilot boards.
