The Venus827 is a single-chip GNSS receiver containing RF and baseband in a 5mm x 5mm BGA64 package. Featuring high performance SkyTraq Venus 8 positioning engine, the Venus827 provides good sensitivity and very short TTFF with no host interaction needed. Venus827 is intended for high-volume GNSS dead-reckoning or precision timing applications.

For dead-reckoning application using 6-axis IMU such as BMI160, Venus827 can support Automotive Dead Reckoning (ADR) mode if the vehicle wheel-tick odometer signal is available; or operate in Odometer-less Dead Reckoning (ODR) mode if the odometer signal is unavailable.

For precision timing application, the Venus827 supports TRAIM and precise 1PPS generation down to using a single satellite.

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.

The Venus827 is suitable for next generation of very high performance GNSS applications requiring 100% positioning availability, or precision timing synchronization applications.
