Mockbird UC6225

Downsized GNSS BB-RF SoC

Brief Introduction

Developed and manufactured by Unicore Communications, Inc., UC6225 is a BB-RF chip that provides GPS/BDS/SBAS single chip receiver solutions. Based on proprietary GNSS technology, the chip can receive satellite signals from GPS L1 and BDS B1 simultaneously. Integration solutions cut down the numbers of peripheral parts and hardware costs, all contributing low-cost, minimum-space occupying and high-performance positioning service and customer experience.

UC6225 is compatible with BDS and GPS and provides flexible options of dual-system and single-system positioning. 64 channels can be run simultaneously. Highly sensitive Ultra-sense base band design enables effective positioning in urban canyons and other complex environments. With simple pin, compact body and redundant peripheral designs cut off, the chip is a perfect fit for vehicle on-board monitoring and navigation, personal tracking, portable navigation and other consumer-oriented applications.
