## Overview <a href="#descriptions" id="descriptions"></a>

These GPS uses multi-constellation GNSS powered by u-blox M10, M9N, and M8N series, a concurrent GNSS receiver that can receive and track multiple GNSS systems. Owing to the multi-band RF front-end architecture, all four major GNSS constellations, GPS, Galileo, GLONASS, and BeiDou, can be received concurrently.\
\
It also comes with the IST8310 compass, tricolored LED indicator, buzzer, and a safety switch.  The high-gain 25 x 25 mm2 patch antenna provides excellent performance, and the omnidirectional antenna radiation pattern increases flexibility for device installation.\
\
There are 3 different connector options for different purposes. Please Pinout page for more details.

## V2 Changes

* New casing with IP67 rating
* Removed buzzer and safety switch to reduce EM/RF interference
* Removed safety switch LED and GPS Fix LED
  * Only the RGB UI LED controlled by the flight controller is present for better status recognition
* Added SAW filter and receiver shielding for better signal integrity
* Legacy Pixhawk Molex 6+4+3 connector option no longer available (can be purchased separately [here](https://holybro.com/collections/gps-accessories/products/gps-extended-length-cable-42cm?variant=45736755396797))
