GPS is such an <a href="https://www.sciencefriday.com/segments/gps-shaped-world/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">essential part of our lives</a> 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,<a href="https://bookshop.org/p/books/little-blue-dot-how-gps-shaped-the-modern-world-katherine-dunn/ca81acf9a0e24c66?ean=9781639734313&affiliate=18570" target="_blank" rel="noopener noreferrer"> “Little Blue Dot: How GPS Shaped the Modern World.”</a>
