ASIL positioning software engine pairs with TeseoAPP for precision in AVs

Point One Navigation’s FusionEngine software is ASIL-rated for precision location operations in autonomous vehicles (AVs).

When paired with STMicroelectronics TeseoAPP (Teseo ASIL Precise Positioning) GNSS chipset, it offers a competitively priced, production-ready positioning system for navigation and advanced driver assistance systems (ADAS), says Point One Navigation. It said that the combination assures functional safety at ASIL-B, a critical requirement for Level 3+ ADAS systems.

FusionEngine is built on the company’s proprietary self-calibrating, sensor fusion algorithms. It combines data from multiple sensors, including the TeseoAPP multi-band GNSS receiver for high accuracy.

It can be easily integrated into a variety of host processors that are used for enabling Level 3+ ADAS and autonomous driving systems.

The 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 the FusionEngine is integrated. The TeseoAPP receiver and chipset comply with ST’s Automotive Grade qualification, including AEC-Q100 and ISO 26262.

The FusionEngine enables developers to complete the functional safety concept phase for the host system software integration. This includes the definition of safety goals, functional and technical safety requirements 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.

“Building on the foundation of ST’s TeseoAPP, we are enhancing safety in production automotive applications,” said Aaron Nathan, CEO at Point One Navigation. 

Tomorrow’s vehicles, equipment, and devices require continuous precise knowledge of their location to be safe and effective in the real world. Point One says it is delivering the first precise positioning solution that is both cost effective and works anywhere. Its location platform comprises satellite navigation, computer vision, and sensor fusion. It is claimed to outperform other options by tightly coupling the strengths of different sensor modalities and intelligently using proprietary data. 

Point One is headquartered in San Francisco, California, USA.
