SARSAT (search and rescue satellite-aided tracking)

SARSAT (search and rescue satellite-aided tracking)click for a larger image
A system of satellites operated by Canada, France, and the United States for search and rescue purposes. The system, along with the equivalent system COSPAS of the former Soviet Union, monitors distress signals from ships and aircraft. The ship or aircraft in distress must transmit the distress signal on one of the two fixed frequencies. The system uses NOAA (National Oceanic and Atmospheric Administration) satellites in low-earth and geostationary orbits to detect and locate aviators, mariners, and land-based users in distress. The satellites relay distress signals from emergency beacons to ground stations and ultimately to the U.S. mission control center in Southland, Maryland. The USMCC (United States Mission Control Center) processes the data and alerts the appropriate search and rescue (S and R) authorities. SARSAT is a part of COSPAS-SARSAT.

Doha Joint Rescue Co-ordination Center (DJRCC) and Turkish Search and Rescue Center have signed a memorandum of understanding (MoU) at the ongoing 33rd meeting of the Satellite-Aided Search and Rescue Initiative (Cospas-Sarsat Programme) in Doha.
COSPAS-SARSAT is an international satellite-based search and rescue distress alert detection system established by Canada, France, the former Soviet Union, and the U.S.
The FCC's ruling should come as no surprise because the international Cospas-Sarsat search-and-rescue program stopped monitoring the 121.5 MHz frequency in 2009 due to reliability and false alert concerns.
It will enable Canada to meet its obligations under the International COSPAS-SARSAT Program Agreement.
They include: the International Cospas-Sarsat system, a satellite to facilitate search-and-rescue missions; personal locator beacons; various sources of satellite imagery and products; automatic identification systems on ships; land-based receiving stations operated by the Marine Exchange of Alaska; and the long-range identification and tracking system and sensors on Coast Guard cutters and aircraft.
Other areas where both nations could potentially collaborate include help with satellite based search and rescue missions - whether for missing fishermen or for maritime security - under the ambit of the COSPAS-SARSAT agreement, said Dr P.G.
Additionally, as an expert provider of Cospas-Sarsat technology, McMurdo will seamlessly connect the Kenyan RCC to the Italian Mission Control Center (MCC), which will allow the RCC to receive beacon distress alert data.
The RCTM discovered that Cospas-Sarsat 406MHz beacons with integral GPS receivers suffered from poor cold start performance, causing delays in providing accurate location information to Search and Rescue (SAR) authorities.
The satellite will also house a transponder that will allow it "to immediately detect distress signals from emergency beacons and relay them to ground stations." It is a part of NOAA's responsibilities as the operator of ( Search and Rescue Satellite Aided Tracking (SARSAT) System, one of the components of COSPAS-SARSAT that helps detecting and locating "mariners, aviators, and other recreational users in distress almost anywhere in the world at anytime and in almost any condition."
Currently, there are several advanced devices available in the market such as 406 MHz frequency transmitters, which offer accurate information, maximize search and rescue resource management, and provide real-time emergency tracking and response through the use of a network of satellites known as Cospas-Sarsat system.
Operating on the 121.5 MHz international air distress frequency as well as Cospas-Sarsat alerts at 406 MHz.
