GMV’s accurate and safe positioning solution is now on the road

GMV’s positioning solution comprises two components: an onboard Positioning Engine software (PE) and a GNSS Correction Service (CS). The CS provides BMW Group vehicles with corrections to the Broadcast Ephemeris for different GNSS constellations, augmentation data to remove local atmospheric effects and safety-related information for computing a reliable user position. The PE integrated in the vehicles’ on-board unit also uses the corrections, together with GNSS signals and information from other sensors, to compute a trustable vehicle position, speed, and heading.

Both CS and PE have been developed, validated, and evolved over the last years in order to be able to cope with the requirements laid down by the different GNSS-based high accuracy positioning markets including the automotive market. The latter has been the latest challenge taken on by GMV within its positioning solution, for which ISO 26262 (among others), the strictest automotive standards, plus the highly demanding quality practices for critical software were adopted.
