Description
Unit GPS v1.1 is a GNSS global positioning and navigation unit, utilizing the AT6668 solution with a built-in ceramic antenna to provide more precise and reliable satellite positioning services. Compared to previous products, the AT6668 supports multi-frequency, multi-mode GNSS signal reception, capable of receiving signals from multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS), supports both multi-system combined positioning and single-system standalone positioning, and offers stronger anti-interference capability and higher positioning accuracy. In areas with weak signals, it can quickly obtain higher-precision location information. This module is applicable to high-precision positioning scenarios such as in-vehicle navigation and IoT positioning devices.
