The Venus828F is a high performance, low cost, single chip GNSS receiver module targeting mobile consumer and industrial applications. It offers low power consumption, high sensitivity, and best in class signal acquisition and time-to-first-fix performance.
Venus828F contains all the necessary components of a complete GNSS receiver, including GNSS RF front-end, GNSS baseband signal processor, 0.5ppm TCXO, LDO regulator, DC/DC switching regulator and passive components. It takes up only 49mm2 PCB footprint.
Dedicated massive-correlator signal parameter search engine within the baseband enables rapid search of all the available satellites and acquisition of very weak signal. An advanced track engine allows weak signal tracking and positioning in harsh environments such as urban canyons and under deep foliage.
Venus828F is very easy to use and offers very fast time to market.
