GPS/BDS Unit with SMA Antenna (AT6668)

This GPS Unit is a GNSS (Global Navigation Satellite System) global positioning and navigation module built with the ATGM336H navigation system that's powered by the AT6668 chip. It has an external SMA antenna that provides accurate satellite positioning. Supporting multi-frequency and multi-mode GNSS signal reception, it is compatible with various satellite systems, including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS. You have the choice of either combined multi-system positioning or independent single-system positioning, which greatly improves resistance to interference and the accuracy is more precise. It can be used for many different positioning projects, such as vehicle navigation, IoT location devices, and other scenarios, even in areas with weak signal coverage. Features

* Supports multiple satellite navigation systems (GPS/QZSS/BD2/BD3/GAL/GLO)

* Multi-Frequency and Multi-System Reception

* Multi-Channel Support

* External Active Antenna

* 2x LEGO-Compatible Holes

* Programmable platforms: Arduino, UIFlow, ESP-IDF, etc.
