In contrary to conventional GNSS systems, PATHFINDER is a complete GNSS software stack that integrates seamlessly with Advanced Driver Assistence Systems (ADAS) or other mobile platforms. PATHFINDER is substituting the hardware GNSS receiver by using graphics acceleration resources.
The best possible localization performance is always the result of sensor data fusion. PATHFINDER reliably estimates the vehicle system state and its confidence, represented by a protection level. Additionally a tightly-coupling of GNSS signals and vehicle onboard sensors achieves an accurate, robust and highly available solution on a mass market price level. This is the basis for the safety critical GNSS integration.
The PATHFINDER digital antenna will be tailored to your needs when it comes to integration into your hardware environment. This keeps costs down and the architecture simple.
A dedicated hardware GNSS receiver plus antenna results in a complex system architecture. An integrated supervision of the receiver performance is not possible.
Our software receiver is integrated into the central sensor fusion platform. This approach leads to a simplified architecture and enables an integrated safety concept.
Exact vehicle positioning is a major challenge for V2X, ADAS and AVs. Future safety critical driving functions also require functional safety (FuSi) down to the sensor layer. NAVENTIK PATHFINDER enables both - a more robust localization even in urban environments and the implementation of FuSi concepts through transparency of the signal pre-processing within receiver framework.
In short, PATHFINDER integrates all safety-relevant aspects of vehicle localization. All steps of signal processing are carefully revised so as not lose or falsify any information relevant for the estimating a valid error budget. The PATHFINDER module will be interfaced by an API tailored to your needs and requirements; as we are targeting the implementation on your ECU or ADAS processor we are carefully developing according to automotive standards and we are also going to comply with ISO 26262.
