UM680A
Automotive Grade Multi-GNSS Dual-frequency High Precision RTK Positioning
Module
UM680A is a high precision GNSS dual-frequency navigation car gps module
developed by Unicore for the intelligent driving market. Based on the
proprietary multi-system dual-frequency high-performance SoC-UC6580A, the
module supports multi-system dual-frequency joint positioning with centimeter-
level accuracy, and it operates at temperatures up to 105 °C.
Ordering Information
Supply at multiples of 250 pieces
Product Characteristics
Supports concurrent operation of vechicle gps, BDS, GLONASS and Galileo
Dual-frequency single point positioning, providing higher accuracy and
reliability
