                            
                        UM670A is a GNSS dual -frequency navigation module developed by Unicore for the intelligent driving market. Based on the proprietary multi -system dual-frequency high-performance SoC - UC6580A, the Module supports concurrent operation of GPS, BDS, GLONASS*, Galileo, QZSS and NavIC*. Different sub-models use different frequencies (L1+L5 or L1+L2) to perform single point positioning and also provide raw data output.
