Proven technology
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.
Safety-critical certified
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:
- ASIL-B (ISO 26262 – ISO 21448) Standards for Safety- Critical Applications
- ISO 21448 (SOTIF Safety of The Intended Function)
- A-SPICE CL3 (Automotive SPICE® Capability Level 3)
Best-in-class performance
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:
- Horizontal Accuracy* < 10 cm RMS
- Target Integrity Risk up to 10-7/h
- Service Availability (SLA) > 99,9 %
- Convergence time < 30 s with reconvergence in seconds
* Nominal accuracy achieved with a mass-market automotive and GNSS receiver under open sky conditions
Highly flexible
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.
