Description

Module GPS v2.0 is a high-performance GNSS global positioning module, integrating the high-performance AT6668 chip, providing accurate and reliable satellite positioning services. The module supports multi-frequency and multi-mode GNSS signal reception, compatible with multiple satellite navigation systems, including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS, enabling high-precision, multi-system joint positioning or single-system independent positioning, with excellent anti-interference capabilities. In areas with weak signals, it can quickly obtain higher-precision location information.

The module comes with a default SMA antenna. Additionally, the module is equipped with a DIP switch, allowing users to flexibly switch TX/RX communication pins and perform precise timing settings through PPS signal output. The module supports multiple stacking uses, providing more customization possibilities and flexibility, suitable for high-precision positioning applications such as vehicle positioning and navigation, IoT positioning devices, remote monitoring, smart cities, home and industrial automation.
