Radio Stations and Systems – Article 1.93), these transmit a coded data burst once every 50 seconds, conforming to the C/S T.001 Specification for Cospas-Sarsat 406 MHz Distress Beacons, compatible with the Cospas-Sarsat satellite receivers. The different types include: ELTs (emergency locator transmitters) signal aircraft distress

As a result of the "Verdunkelung", a black-out measure for aerial defense from 1935, cobalt blue was regulated to replace the red color used until 1938 in German emergency vehicle lights. [1] [2] Due to the scattering properties of the blue color, it is only visible to lower altitudes and is therefore less easily spotted by enemy airplanes.
Bluetooth beacons use Bluetooth Low Energy proximity sensing to transmit a universally unique identifier [1] picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, [ 2 ] track customers, or trigger a location-based action on the device such as a ...
Military aircraft use 243 MHz (which is a harmonic of 121.5 MHz, and therefore civilian beacons transmit on this frequency as well). Aircraft can also signal an emergency by setting one of several special transponder codes, such as 7700.
