SARSAT
SARSAT (Search and Rescue Satellite-Aided Tracking) is a system that uses satellites to detect and locate emergency distress beacons activated by aircraft, ships, and individuals in distress. The system operates on a frequency of 406 MHz and provides global coverage. When a distress beacon is activated, the signal is detected by the satellites and relayed to a ground station. The ground station then forwards the distress signal to a Rescue Coordination Center (RCC) which coordinates the search and rescue mission. SARSAT has been responsible for saving thousands of lives since its inception in the 1980s.
