Commercializing Localization for Automated Driving: Absolute vs. Relative
In order for an AV to navigate automatically and reliably, it must be able to locate itself on a map with high precision and always maintain its position accurately. This is called real-time precision localization.
Precision localization based on absolute positions from multiple measurements coupled with GNSS correction is currently being commercialized in L2+ automated applications. As of now, taking advantage of such technologies is the most practical way to commercialize precision localization systems and meet production cost targets of passenger vehicle OEMs as opposed to landmark-based relative localization approach.
This article will examine the fundamentals of precision positioning technologies and identify major players in this space.
