Global navigation satellite systems specialist GMV has integrated its positioning technology GMV GSharp into the BMW Personal Pilot Level 3 (L3) functionality of the new 7 Series.
Level 3 automated driving represents an advancement in autonomous vehicle technology, enabling vehicles to handle specific driving tasks independently within defined conditions – human intervention is required only when the system encounters situations beyond its capabilities.
GMV GSharp aims to deliver high-accuracy, safe and reliable positioning information, which is essential for automated driving functions. It integrates GNSS with other in-vehicle sensors such as inertial measurement units, wheel speed sensors and odometers to enhance safety and precision. The positioning solution comprises two key components: the Safe Positioning Engine (SPE) software; and the Safe GNSS Correction Service (SCS).
Together, these components are designed to ensure the safety and precision required for Level 3 automated driving applications. The SCS provides BMW vehicles with corrections to the Broadcast Ephemeris across various GNSS constellations, as well as augmentation data to mitigate local atmospheric effects and safety-related information. The SPE uses these corrections, along with GNSS signals and data from other sensors, to compute the vehicle’s position, speed and heading.
The Correction Service and Positioning Engine are developed in compliance with ISO 26262 and ISO 21448 standards, ensuring they meet stringent safety requirements. They also align with the security-from-design principle outlined in ISO 21434, incorporating countermeasures against GNSS-related attacks such as spoofing and jamming.
