Location by Doppler (without GPS) [ edit ]

Since their approval in 2003, like all new electronic devices, plbs have gotten smaller and less expensive, to the point that cost can’t be used as an excuse not to buy one. Plbs with gps ability transmit the gps location and the registered serial number identifying the owner a long with the distress signal, so if the unit has an unobstructed view of the sky, location is detected to within about 100 yards in a few minutes. For units without gps, or when a gps data can not be collected, the location is determined using doppler technology from the signal source to the satellites.

Emergency Locator Transmitters and Beacons

406 mhz beacons designed for use in an aircraft are known as an emergency locator transmitter (elt). Elts can be manually activated by the pilot using a switch on the instrument panel or automatically activated by a g-switch. A g-switch is a mechanism inside the beacon that activates automatically when it detects excessive g-forces experienced during a crash. Elts transmit the distress signal for at least 24 hours. As with epirbs and plbs, some 406 mhz elts may also include a gnss signal within the distress alert. This position may be a one-time input from the aircrafts navigation system or may be periodically updated from a gps processor internal to the elt.
