GPS

Global Positioning System

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.
Without GPS, countless losers who can't use a VOR would be lost"

ADF

Automatic Direction Finder
or
Automatic Direction Finding System

a navagation system used by aircraft and sea-going ships. It consists of one or more ground stations that transmit a signal in the 225 to 500 kHz (.225 to .500 MHz) range. Because of the low-frequnecy of these signals, their range is very good and not limited by the line-of-sight range of the VOR system. The recevier in the airplane/boat uses a loop antenna to "home-in" on the station. There is also a long-wire receiving antenna installed on many aircraft. Most ADF receivers can also recieve the AM broadcast band (530 to 1710 kHz) so pilots can also home in on powerful broadcast stations.

ADF signals should not be used in thunderstorms because the high amount of electro-magnetic interferance that lightening causes.

Many pilots can't even use the ADF system, which is a shame, becuase of better systems such as VOR and the GPS systems.
