GPS technology at it's best!

GPS-guided positiong system, which enables the user to get an earth centered earth fixed position,used for data collection or navigation, on or beneth the earths surface. this technology is great for people who love to go into the backwoods,hunters ect. It is also a great tool for surveying and plotting maps. The only thing that i thought was ironic is that the government can control the signals so that the gps users don't always have an accurate reading.funny !!!
