The National Search and Rescue Plan updated
and signed by participating parties,
including NASA in 2007, states that
"NASA will support Search and Rescue
(SAR) objectives through research
and development or application of
technology to search, rescue,
survival, and recovery systems
and equipment, such as location tracking
systems, transmitters, receivers,
and antennas capable of locating aircraft,
ships, spacecraft, or individuals in
potential or actual distress."
