The design of distress beacons as a whole has evolved significantly since 1982. The newest 406-MHz beacons incorporate GPS receivers. Such beacons transmit in their distress message highly accurate position reports. The distress alert and location are forwarded almost instantly to SAR agencies via Cospas-Sarsat satellites. This provides a second method for Cospas-Sarsat to know the location of the distress, in addition to the calculations independently done by Cospas-Sarsat LUTs to determine the location. This two-tiered reliability and global coverage of the system has inspired the current motto of SAR agencies: "Taking the 'Search' out of Search and Rescue."[http://www.aeromedix.com/aeromedix_articles/plb/index.html]
