Satellite rescue beacon


In Australia, there are LUTs located in Bundaberg, Queensland and Albany, Western Australia which work in cooperation with the New Zealand LUT. The new medium-altitude Earth orbit search and rescue (MEOSAR) system has a LUT near Mingenew, Western Australia and a LUT in New Zealand at Goudies Road on the North Island.

MCCs analyse and distribute distress alerts to the rescue coordination centres (RCC) in the country’s SAR region where the beacon is both activated and registered.

For more than 30 years, since its initial deployment in 1982, the Cospas-Sarsat system has provided valuable emergency distress detection and location information to worldwide search and rescue operators and teams. As part of an international cooperation to make available a free-of-charge search and rescue (SAR) service, the system has been credited with assisting more than 37,000 people all around the world.

The system uses satellite-based payloads, hosted by low Earth orbit (LEO) constellations (LEOSAR), to detect and locate distress signals emitted by emergency beacons carried by mariners and aviators as well as by land-based users. Cospas-Sarsat has relied on its original LEO architecture since declaration of the system’s full operational capability (FOC) in 1985. It was complemented by geostationary (GEO) satellites (GEOSAR) in 1994.

Cospas-Sarsat has proven its efficiency. LEO satellites may locate beacons almost anywhere thanks to Doppler effect with a limited instantaneous coverage. The GEO satellites have a very wide field of view, which offers real-time detection but no possibility of independent location as the Doppler effect is negligible in GEOs.

To improve performance, the system is now undergoing a profound evolution called MEOSAR, which will add SAR capability to middle Earth orbit (MEO) satellites. By the end of this decade, Cospas-Sarsat will rely on a MEO/GEO space segment, replacing the LEO/GEO design, thanks to SAR payloads hosted by three GNSS constellations: GPS, Galileo, and GLONASS.

With numerous satellites, each with an Earth coverage or footprint significantly larger than the LEO satellites (about seven times larger), the MEOSAR constellations will enable an instantaneous and worldwide coverage. Distress beacons will be detected and located more quickly and accurately than today, in as little as one beacon burst, that is, about 50 seconds. The more efficient alert notices that result will directly contribute to the efficiency of rescue operations where time is critical.

While deeply rewarding, backcountry adventures also entail risks that can occasionally prove life threatening—even for the most experienced outdoor enthusiasts.

Though both are portable transmitters, personal locator beacons and satellite messengers have some important distinctions. This article covers the basics of each.

Personal locator beacons are high-powered (typically, 5 watts) devices designed primarily to send out a personalized emergency distress signal. They generally require an open view of the sky to transmit successfully.

PLBs are the land-based equivalents of Emergency Position Indicating Radio Beacons (EPIRBs), a technology that has been in use for decades in marine environments. Over the years, these devices are estimated to have saved more than 33,000 lives.

Important: A Personal Locator Beacon should be activated only in situations of grave and imminent danger, and only as a last resort when all means of self-rescue have been exhausted.

PLBs transmit powerful signals at 406 MHz (MegaHertz), an internationally recognized distress frequency monitored in the U.S. by NOAA (National Oceanic and Atmospheric Administration) and the AFRCC (Air Force Rescue Coordination Center).
