Humbird UC220

BDS+GPS/GLONASS/GALILEO Low Power GNSS SoC

Brief Introduction

Unicore HumbirdTM is a low-power GNSS SoC using advanced 55nm process technology and independent intellectual property rights GNSS algorithm, while running a 64 channel, providing users with ultra low power consumption, ultra high-performance location service and user experience.

HumbirdTM SoC supports single system independent positioning and BDS+GPS/GLONASS/GALILEO dual-system interoperation, and is flexible for configuration. 

With unique “Ultra-Sense” high sensitivity base-band design, the receiver can remain well positioning effect in the urban canyon and other complex environment. At the same time, thanks to innovative “Rhythm Sleep” technology, HumbirdTM can run at very low power levels. The simple, compact design make it most suitable for portable navigation and GIS handheld applications besides vehicle control, navigation, timing and other professional applications.
