Point One’s ASIL-rated navigation solution is targeted at automotive and ADAS system manufacturers who require an easy-to-integrate, system that enables precise positioning for vehicles.

Point One Navigation has released an ASIL Positioning engine to enable safe and precise autonomous vehicles. The module incorporates a Point One’s FusionEngine and STMicroelectronics’s TeseoAPP Chipset.

The module provides a production-ready positioning solution for automotive OEMs developing navigation and advanced driver assistance systems (ADAS). The combined solution assures functional safety at ASIL-B, a critical requirement for Level 3+ ADAS systems.

The FusionEngine used in the module is a tightly coupled positioning solution built on the Company’s proprietary self-calibrating sensor-fusion algorithms. The FusionEngine is capable of combining data from multiple sensors, including ST’s TeseoAPP multi-band GNSS receiver, to assure the high accuracy, safety, and integrity required for higher levels of autonomous vehicles. Fusion Engine can be easily integrated into a variety of host processors that are used for enabling Level 3+ ADAS and autonomous driving systems.

The combination of ST’s TeseoAPP receiver and the STA5365S external RF front-end provides dual-band precise raw measurement data for all visible GNSS satellites to the main host processor, where Point One’s FusionEngine is integrated. The TeseoAPP receiver and chipset are compliant with ST’s Automotive Grade qualification. This includes AEC-Q100 and ISO 26262.

“Building on the foundation of ST’s TeseoAPP, we are enhancing safety in production automotive applications,” said Aaron Nathan, CEO at Point One Navigation. “We’ve leveraged ST’s expertise in automotive-grade qualification to bring to market a complete solution that offers both high performance and reliability. Our customers can now achieve ASIL B safety for today’s most advanced vehicle applications.”

Point One’s FusionEngine enables developers to complete the Functional Safety Concept Phase for their host system software integration. This includes the definition of Safety Goals, Functional Safety Requirements (FSR) and Technical Safety Requirements (TSR) as well as the test methods to provide evidence of successful integration. These test methods are then fully executed and audited to achieve the assigned ASIL rating.
