International Cospas-Sarsat is like having a superhero team ready to help people who are lost or in danger. They keep an eye on the sky and the ocean with special gadgets called satellites. These satellites are like big cameras that can see things from high up in space.
When someone's in trouble and they press a special button on a device called a Personal Locator Beacon, the satellites can find them and send a message to people on the ground who can help. This is really important if someone is lost in a remote area or if a plane or boat gets into trouble in the middle of the ocean.
Cospas-Sarsat is made up of many countries, who work together to make sure that the satellites are always working and that people can be rescued quickly. This is useful because sometimes people in trouble don't speak the same language as the rescuers. So, everyone in the Cospas-Sarsat program uses the same special language to talk about emergencies, no matter what country they are from.
In short, Cospas-Sarsat is a group of super powered satellites and superhero teams from many countries who work together to help people when they need it most.
