In a recent Wireless Watch issue, we reported on a collaboration between Vodafone and US precision positioning systems designer, Topcon Positioning Group. The focus of their collaboration, Vodafone GNSS Corrections, aims to improve the accuracy of global navigational satellite systems (GNSS) from multiple meters down to centimeters when connected to Vodafone’s IoT network. For this, it will rely on Topcon’s own system of GNSS stations, in particular its European presence. Sub-meter accuracy is a critical barrier to be broken for many IoT and autonomous automotive or robotics applications. Knowing the position of a car to an accuracy of five meters may be useful for general navigation, but for autonomous driving purposes, this could very quickly prove fatal. Centimeter precision could…
