How Uber moves the ‘blue dot’ to improve GPS accuracy in big cities

Recently, I sat down with two Uber engineers who may have a solution for all this chaos. Andrew Irish and Danny Iland were both PhD students at UC Santa Barbara when their startup Shadow Maps was acquired by Uber in 2016. Since then, they’ve been working on integrating their technology into Uber’s app. They recently began beta testing in 15 cities across the globe, and based on early results, they are now getting GPS signals that are twice as accurate as before.
