The GPS (Global Positioning System) has become a little like air or sunshine these last few years... so common and ubiquitous that you don't even think about it. The other day, I got in the Tahoe and it took about 1 minute before the system could lock onto the satellites and I remember thinking, "This is taking forever. What is going on?"
We've all (or most of us) have become so reliant on the system that we don't even think about it. Cell phones, cars, UPS, even the watch I wear when I run can access the satellites for instant location services.
Now the system is getting an upgrade that will make it much more accurate and much more reliable. It will cost 8 billion dollars, but when you really think about what it does, the world cannot do without it.
For a great article on the service and the upgrade, check out this article in the LA Times.
