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"

ELT

Emergency Locator Transmitter. The ELT is a small radio transmitter that is installed in an aircraft and is designed to being transmitting upon impact (the crash) or it can be manually switched on. The ELT transmits a distincive signal on the international emergency frequencies of 121.5 MHz (VHF) and 243.0 MHz (UHF). This signal is picked up by ground stations, search and resuce aircraft (see Civil Air Patrol and Coast Guard, and satelites. Direction-finding equipment is then used to "home-in" on the signal and locate the downed aircraft.

Click on the recording above to listen to the sound of real ELT radio signal.

APCO P-25

New digital modulation type, labelled as "APCO Project-25" P-25 pretty much is the same modulation that cell phones use. P-25 is supposed to give better voice quality, but there really is no differance. Plus I need to buy a new radio scanner now.

There are two types of P-25, 3,600 baud and 7,200 baud speeds.
