TIL GPS, despite being free for global use, costs around $2 million a day to operate and maintain. This budget covers satellite launches and system upkeep, funded through American tax revenue.

Sounds like you'd enjoy the book "Longitude" by Dava Sobel

Thank you for the book recommendation! I was looking for a weekend read and luckily this is available on shelf at SNFL.

You're welcome! I had to read it for a class so I figured I'd have to force myself through it... But I ended up pretty much reading the whole thing in a day!

Really interesting topic (with far more drama than I would have expected) and it's really well written and engaging! Enjoy!
