What is the transmitter used to locate the aircraft in an emergency?

Explanation:
In an emergency, the transmitter used to locate the aircraft is the Emergency Locator Transmitter. The ELT automatically or manually activates and sends a distress signal on dedicated frequencies so search-and-rescue services can find the aircraft. Modern ELTs transmit on 406 MHz to satellites (with location data sent to authorities), and also use 121.5 MHz for directional homing by rescuers. This is different from GPS, which provides navigation positioning, and from VOR or DME, which are ground-based navigation aids and not distress beacons.
