This GPS Unit is a global navigation module that provides accurate satellite positioning services. It combines the CASIC navigation chip AT6668 with the MAX2659 signal amplifier chip and has a built-in ceramic antenna for better positioning performance.

The AT6668 chip supports multi-frequency and multi-mode GNSS signal reception, letting it work with multiple satellite systems such as GPS, BD2, BD3, GLONASS, GALILEO, and QZSS. This allows it to provide combined positioning using multiple systems or standalone positioning with a single system.

With improved anti-interference and positioning accuracy from the original unit, the GPS Unit v1.1 can quickly acquire precise location data, even in areas with weak signal strength (Those pesky mountains!)
