Description
GPS Unit v1.1 is a GNSS global positioning navigation unit, integrating the high-performance CASIC navigation chip AT6668 and signal amplifier chip MAX2659, with a built-in ceramic antenna, providing more precise and reliable satellite positioning services. Compared to previous products, AT6668 supports multi-frequency and multi-mode GNSS signal reception, receiving signals from multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS), supporting multi-system combined positioning as well as single-system standalone positioning. It has enhanced anti-interference capability and higher positioning accuracy, allowing it to quickly acquire high-precision location information in areas with weak signals. This module is widely applicable in high-precision positioning applications, such as in-vehicle positioning and navigation, IoT positioning devices, and more.
