Safe positioning service
PointSafe is a safe positioning service composed of an ISO 26262-certified safe correction service and safe on-board position engine software that are already on the road today, delivering high performance and trusted positioning for next- generation autonomous driving vehicles.
PointSafe meets the ASIL-B (ISO 26262) and SOTIF (ISO 21448) standards for Safety-Critical Applications and is among the few services available in the market today to meet standards for the functional safety of road vehicles. PointSafe comes with SOTIF features, which means that SOTIF (ISO 21448) compliance is possible depending on customer requirements. PointSafe is exactly suited for Advanced Driver Assistance Systems (ADAS) defined by the automotive industry, and directly suited to the SAE Levels 3-5. Our focus is positioning, integrity, and functional safety, always considering the needs of customers and applications.

PointSafe provides a precise and safe algorithmic solution for highly demanding autonomous driving. It is a complete GNSS safe positioning service composed of a safe position engine and safe correction service.
PointSafe’s safe correction service and safe on-board position engine are on the road today, delivering high performance and trusted positioning for automotive Tier 1’s and OEMs. This proven technology has been tested over millions of miles and is part of first safe solutions on public roads. Years of research and development have culminated in a mature and proven solution ready for the market.
PointSafe meets the ASIL-B standards for Safety-Critical Applications. ASIL refers to Automotive Safety Integrity Level, a risk classification system defined by the ISO 26262 standard for the functional safety of road vehicles. Integrity + Functional Safety is recognized as a critical capability for ADAS SAE L3-5; therefore, the service complies with the following standards:
Achieving a sufficient performance requires a holistic solution based on GNSS hardware, software, and service. PointSafe provides best-in-class performance for accuracy, integrity, and availability:
* Nominal accuracy achieved with a mass-market automotive and GNSS receiver under open sky conditions
Natively supported by best-in-class u-blox A9 functional safety chipsets and modules and in adding customized integration support, PointSafe is a core component of u-safe end-to-end safe positioning solution, providing a proven one-stop-shop for advanced driving. PointSafe also offers the configurability and flexibility to support non-u-blox automotive grade components and is usable as a standalone option for customer solutions.
