Cospas-Sarsat system description
Cospas is an acronym for the Russian words Cosmicheskaya Sistyema
Poiska Avariynich Sudov, which means “Space System for the Search of
Vessels in Distress”. The Cospas-Sarsat system was introduced in 1982 as a
worldwide search and rescue system with the help of satellites covering the
earth’s surface. Between 1982 and 2018 alone this system has aided in
rescuing at least 48,738 individuals in 14,531 search and rescue situations.
Currently, the system consists of 5 functional satellites in a polar orbit
constellation, these satellites cover the entire earth’s surface and receive
distress signals from the 406 MHz transmitter within the Tron 40VDR, more
polar orbiting satellites will be available in the future, giving a faster
location and rescue time.
