Centennial Science and Technology GPS module manufacturer, BU12M8B module, can be used in 3 product level multi-functional GNSS chip modules, with GNSS engine excellent performance, and using industry-certified NEO packaging. The BU12M8N module can receive up to 2 GNSS systems(GPS and Beidou) at the same time, and can identify multiple constellations at the same time, providing excellent positioning accuracy in urban canyons or weak signal environments. In order to improve positioning performance better and faster, it also supports message integrity protection, geographic fencing and fraud detection, and has configurable interface settings that can easily adapt to customer applications.
Product Advantages:
1. Parallel reception of up to 2 GNSS(GPS, Beidou)
2. Industry leader-167dBm navigation sensitivity
3. Minimum current consumption in industry
4. High position accuracy can also be achieved in urban canyons
5. Security and integrity protection
6. Support for all satellite enhancement systems
7. Operating temperature range for automotive chips -40 °C to +105 °C
