Product Description:

UM680A

Automotive Grade Multi-GNSS Dual-frequency High Precision RTK Positioning Module

The UM680A represents a high-precision GNSS dual-frequency navigation module designed by Unicore specifically for the intelligent driving sector. It is built upon the proprietary multi-system dual-frequency high-performance System on Chip, UC6580A, enabling the module to facilitate either multi-system dual-frequency joint positioning or single-system standalone positioning, achieving centimeter-level accuracy.

APPLICATIONS

• Intelligent Driving

Product Characteristics


• Supports concurrent operation of GPS, BDS, GLONASS and Galileo	• Supports A-GNSS to reduce the TTFF
• GNSS chip qualified according to AEC-Q100 and production process conforms to IATF16949	• Anti-jamming design to ensure the module working stably in complex electromagnetic environment
• Centimeter-level positioning accuracy & raw data output
