Wife: But I don't know how to get there, We have been there at least 30 times, but I'm a women, so I just can't remember.
Husband: Don't worry, I got you this brand new GPS, it talks to you and tells you how to get to places you should already know how to get to.
Wife: Now I can finally drive outside the neighborhood without getting lost! YAY! :)
Complex network of satellites that transmit signals to ground receviers in cars, boats, airplanes (see also VOR). The GPS receiver uses the signals from the satellites (which are over 15,000 miles away!) and uses them to find your location, anywhere in the world, with incredable accuracy.
Omg I nearly choked when I walked through those gp's perfume cloud.
