What is the difference between an emergency beacon with Global Positioning System (GPS) and one without GPS?
An emergency beacon with GPS – a location protocol beacon – has GPS encoded in its transmitted signal. There are two types of location protocol beacons: those with a built-in GPS and those with an externally connected GPS. The GPS is a navigation and precise-positioning tool. A GPS device may take a few minutes to establish its position. An external GPS connected to a location protocol beacon may be able to provide a location on the emergency beacon’s first transmission whereas a built-in GPS may not transmit a location until the second subsequent transmission.
