AUTOMOTIVE GNSS/INS

PolyNav 3000A

The PolyNav 3000A is a high-performance positioning system designed for the automotive market. It is integrated with a multi-constellation GNSS receiver and a MEMS IMU. With the built-in RTK engine, it delivers up to centimeter-level positioning accuracy. Fusing wheel speed and the gear position from the vehicle, the PolyNav 3000A provides continuous positioning, velocity, attitude and time synchronization, even in GNSS-challenged environments and during GNSS outages.
The PolyNav 3000A is scalable for high-volume applications and is developed to support autonomous driving level 2 and above (L2+). It can be deployed in passenger vehicles for multiple ADAS (Advanced Driver
Assistance System) features, such as highway driving assist and automated valet parking features. Furthermore, it can be integrated into self-driving buses and robotaxi.
