Getting There from Here: Local Writer Publishes Book About GPS

We live in a world dependent on the Global Positioning System, or GPS.  It powers our navigation systems, smart phone apps and lets us here at WFDD synch perfectly with NPR programs like Morning Edition and All things Considered.  Roger Easton was one of the key scientists behind GPS.  A few years ago, his son Richard began writing a book about his father's work.  Around the same time, Kernersville writer Eric Frazier's curiosity was picqued when his daughter bought a GPS unit and stopped calling him for directions.  The two men joined forces and recently published GPS Declassified - From Smart Bombs to Smartphones.  Frazier dropped by the studio, while Easton joined him by phone, to discuss the prevalence of GPS in our lives with WFDD's Audrey Fannin.
