Product Description

Unit-GPS SMA is a GNSS global positioning and navigation unit, integrating the high-performance ATGM336H navigation module from Microelectronics, based on the AT6668 chip design. It is equipped with an external active antenna, offering more precise and reliable satellite positioning services. Compared to previous models, the AT6668 supports multi-frequency and multi-mode GNSS signal reception, enabling compatibility with multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS). It supports combined multi-system positioning or single-system independent positioning, offering enhanced interference resistance and higher positioning accuracy. This module is well-suited for high-accuracy positioning applications such as vehicle navigation, IoT location devices, and more, even in weak signal areas.
