Relevant Information: Comparing GPS/BDS Unit v1.1 and Unit-GPS SMA
GPS Unit v1.1 is a GNSS Global Positioning System navigation unit that integrates CASIC's high performance navigation chip AT6668 and signal amplifier chip MAX2659, with a built-in ceramic antenna, providing more accurate and reliable satellite positioning services. Compared with previous products, AT6668 supports multi-frequency and multi-mode GNSS signal reception, receives signals from multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO and QZSS), and supports multi-system combined positioning as well as single-system stand-alone positioning. It has enhanced anti-jamming capability and higher positioning accuracy, allowing it to quickly acquire high-precision location information in areas with weak signals. This module is widely used in high-precision positioning applications such as in-vehicle positioning and navigation, IoT positioning devices, and more.
