ASIL Positioning Engine To Enable Precise Positioning for Autonomous Vehicles

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

Point One Navigation released an ASIL Positioning engine to enable safe and accurate autonomous vehicles. The module includes 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 integrated solution guarantees ASIL-B functional safety, 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 algorithm. FusionEngine is able to combine data from multiple sensors, including ST’s TeseoAPP multi-band GNSS receiver, to ensure the high accuracy, safety, and integrity required for higher levels of autonomous vehicles. The Fusion Engine can be easily integrated with various host processors 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 conforms to ST’s Automotive Grade qualification. This includes AEC-Q100 and ISO 26262.

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

Point One’s FusionEngine allows 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 test procedures to provide evidence of successful integration. These test procedures are fully implemented and audited to achieve the assigned ASIL rating.
