Brief
In this episode of the Pez family podcast, discover how the Global Positioning System uses satellites orbiting 12,000 miles above Earth to pinpoint your exact location! Learn how GPS started as a military technology, how your device uses trilateration by talking to at least four satellites at once, and the incredible atomic clocks that keep time accurate to one-billionth of a second. Explore how GPS revolutionized navigation, helps farmers plant crops with precision, tracks wildlife migrations, assists airplane pilots, and even proves Einstein's theory of relativity! Try hands-on triangulation activities and learn why you'll never get lost again.
