COSPAS/SARSAT: An overviewThe SARSAT/COSPAS satellite network uses 121.5 and 406 MHz buoys to locate ships and aircraft in distress. The 121.5 MHz system, obligatory on many aircraft, gives localization to within 10 km, and, despite being subject to considerable radio interference and a poor signal to noise ratio, is responsible for saving nearly 200 lives. The 406 MHz location error is 2 km in 75% of cases, and less than or equal to 2 hr for 95% of cases in the worst conditions. It suffers however from interference from illegal broadcasts in the frequency band.
