GMV takes part in the webinar “High precision GNSS enables new automotive applications”

On January 17, José Luis Carretero, GMV’s embedded engineer at BMW, gave a presentation during the webinar “High precision GNSS enables new automotive applications”, organized by Rohde & Schwarz, where he discussed some of GMV’s automotive solutions, including GMV GSharp ^® for Automotive.

The session covered a variety of topics, such as basic principles of high-precision GNSS, how GNSS networks and error correction work, and using high-precision GNSS technologies in automotive applications. During his presentation, the GMV engineer stressed the benefits of GNSS technologies in general, while also highlighting the specifics that set GMV GSharp ^® for Automotive product apart from the competitors.

Using a GNSS-based solution is the only way to meet the demanding ADAS requirements, as well as providing absolute positioning with sub-decimal precision, independence from other sensors, global coverage, speed, orientation... all at the same time.

In the webinar, José Luis Carretero explained that GMV GSharp ^® for Automotive works on two key pillars that enable High-Precision Positioning and Reliability: the Correction Service (CS) and the Positioning Engine (PE).

In short, the CS is responsible for processing data from various GNSS stations located around the world and sending them to the end user (PE). These corrections enable the user to eliminate possible errors that could be derived from the positioning techniques, achieving sub-decimal positioning accuracy of around several centimeters.

In this context, not only is positioning performance important in autonomous driving, but a Safety layer is also required on every part of the algorithm to guarantee solution integrity. GMV has invested a great deal of effort in ensuring that all the elements in the chain (e.g. Safety Processor for the Correction Service, Positioning Engine) comply with the ISO26262/SAE21434 standards.

The webinar was divided into two sessions–morning and afternoon–and was attended by some 500 people.
