Data Processing Unit – DPU

The on board Data Processing Unit (DPU) developed by Sensefields integrates a high-performance dual core processor, capable of processing the vehicle data locally, without the need of permanent connectivity. Its modular design allows customizable and flexible configuration tailored to final application and customers’ requirements.

Sensefields DPU integrates a multi-constellation GNSS aided IMU navigation module to enhance positioning, that also allows the deployment of services like robbery detection, driver profile analysis, vehicle-sharing, geo-fencing or geo-location telemetry name a few. Its expansion port is designed to continue adding capabilities like additional capes V2X communications, audio/video processing or additional sensors to be monitored.
