M5Stack GPS/BDS Unit with SMA Antenna (AT6668)

The Unit-GPS SMA represents an advanced global navigation and positioning solution, incorporating the high-performance ATGM336H navigation module from Microelectronics, which is based on the AT6668 chip design. This unit is equipped with an external active antenna that enhances the precision and reliability of satellite positioning services.

Compared to previous models, the AT6668 facilitates multi-frequency and multi-mode GNSS signal reception, thereby ensuring compatibility with various satellite navigation systems, including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS. The system is capable of executing both combined multi-system positioning and independent single-system positioning, which contributes to improved interference resistance and heightened positioning accuracy.

This module is particularly suitable for high-accuracy positioning applications, such as vehicular navigation and IoT location devices, even in environments characterized by weak signal conditions.
