GMV's Precise, Safe Positioning: Enhancing Your Rearview Mirror Experience

GMV has reached another milestone in automated driving by integrating its safe, high-precision and reliable positioning technology as a key component of the BMW Personal Pilot L3 function, the new feature available for order in the new BMW 7 Series.

SAE Level 3 automated driving represents a significant advancement in autonomous vehicle technology. The vehicle automatedly manages specific driving tasks within defined conditions, requiring human intervention only when the system encounters challenges beyond its capabilities. This is a noteworthy departure from more driver-dependent levels, enabling users to disengage under specified circumstances while helping to enhance both comfort and safety on public roads.

The unveiling of Level-3 functionality in BMW 7 Series models establishes the BMW Group as a pioneer in the industry. This accomplishment is a source of pride for GMV, as a significant contributor to it. This signifies a substantial progression from mere driving test trials or proofs of concept to the realization of a fully developed and commercially available solution.

GMV’s proprietary positioning solution consists of two components: the onboard Safe Positioning Engine software (SPE) and a Safe GNSS Correction Service (SCS). 

The SCS and SPE have been implemented and tested with the added goal of compatibility with third-party implementations. However, when they are used together, they achieve full potential in terms of safety, required in Level 3 automated driving applications, as all GMV GSharp^® elements contribute to the overall automated driving solution.

The Safe Correction Service (SCS) provides BMW Group vehicles with corrections to the Broadcast Ephemeris across various GNSS constellations, augmentation data for mitigating local atmospheric effects, and safety-related information for computing a reliable user position. The Safe Positioning Engine (SPE) integrated in the vehicles’ on-board unit also uses these corrections, together with GNSS signals and information from other sensors, to compute a reliable vehicle position, speed, and heading.

This production launch milestone adds the ADL3 function to GMV’s positioning solution market portfolio, consolidating GMV as one of the primary worldwide suppliers of GNSS‑based high‑accuracy positioning solutions.
