How GPS shaped our world
Podcast: Science FridayPublished On: Wed Aug 26 2026
Description: GPS is such an essential part of our lives that it’s easy to forget there was once a world without it. But, like many tech advancements of the 20th century, GPS was originally created by the U.S. military. So how did it become a part of daily civilian life? And how vulnerable is it to manipulation? Katherine Dunn has written all about this and more in her book, “Little Blue Dot: How GPS Shaped the Modern World.” Guest: Katherine Dunn is a science journalist and author of “Little Blue Dot: How GPS Shaped the Modern World.” Transcript will be available after the show airs on sciencefriday.com.
