A New Technique Makes GPS Accurate To An Inch (gizmodo.com)

Posted by BeauHD on Saturday February 13, 2016 @07:45AM from the triangulating-your-position dept.

A team from the University of California, Riverside, has developed a technique that augments regular GPS data with on-board inertial measurements from a sensor. Actually, that's been tried before, but in the past it's required large computers to combine the two data streams, rendering it ineffective for use in cars or mobile devices. Instead what the University of California team has done is create a set of new algorithms which, it claims, reduce the complexity of the calculation by several orders of magnitude. In turn, that allows GPS systems in a mobile device to calculate position with an accuracy of just an inch.

Couldn't the same level of 'automatic' be achieved with image recognition cameras at the doors, or other sensors to achieve the same result?

That's not the case. There's a timelapse between heavy snow and that snow being cleared out by plows -- in some areas it's faster than others. There's significant populated areas where all roads but one main road are snow-covered for months.
