In addition, Rescue Coordination Centers are staffed to read the location that comes from the MCC and make phone calls to the rescue authorities (in the U.S. The signal is processed through a Mission Control Center (MCC), which is staffed 24/7. The satellite then relays the distress signal to user terminals - like the one at Goddard - which process the signal and alert rescue teams. A user activates a distress beacon that broadcasts to satellites within the beacon’s field of view.” The Cospas-Sarsat Program is an international SAR distress alerting satellite system, a network of distress beacons, relay satellites and ground-based user interfaces that alerts rescue teams of people in distress and their locations. Project engineer Chris Dura said, “The SAR system at GSFC is a Medium Earth Orbit Local User Terminal (MEOLUT) in the Medium Earth Orbit Search and Rescue System of the Cospas-Sarsat Program. Lab experts are supplementing legacy reflector antennas with a phased-array antenna system, an element-level-digital phased-array antenna that may offer better performance, reliability and maintainability. Staff members from the Air and Missile Defense Sector at the Johns Hopkins Applied Physics Laboratory (APL) are working with NASA Goddard Space Flight Center (GSFC) and its partners to upgrade NASA’s Search and Rescue (SAR) system. NASA may be best known for focusing on what’s beyond Earth’s atmosphere, but the agency also has another role - searching for human life on our home planet, especially when those lives are in danger.
