Super impressive. Can’t agree more with the author that GPS is a stunningly clever engineering achievement.

For those interested in the story of the development of GPS, I found “GPS Declassified” by Richard Easton to be an engaging retelling.

While reading Amazon reviews, I learned that they missed the contributions by Hedy Lamarr, a very interesting and impressive figure:

a great book to read, much better than you would expect, about Hedy Lamarr, is Richard Rhodes book: "Hedy's Folly."
