SAR- GPS
Abstract
Search and Rescue GPS (SAR/GPS) is an approved auxiliary payload on GPS IIIF beginning no earlier than SV 11. SAR/GPS fills validated National Search and Rescue (SAR) Committee requirements to provide enduring, space-based distress alerting capability to detect, locate, and relay distress alerts to fulfill its responsibilities under international agreements for SAR. In addition, the United States Air Force (USAF) has on-going requirements to rescue US Military personnel in harm's way per AF Doctrine Document 2-1.6. The implementation of a U.S. Medium Earth Orbiting (MEO) SAR Space Segment is via a Canadian-provided 406 MHz SAR repeater on GPS IIIF SVs. This system presents a cost effective, low-risk opportunity that accommodates existing and planned 406 MHz beacons across the globe. Per National Security Presidential Directive (NSPD)-39, USAF and United States Coast Guard (USCG), the U.S. operators of the civil Cosmicheskaya Sistyema Poiska Avariynich Sudov-Search and Rescue Satellite-Aided Tracking (COSPAS/SARSAT) system, and the international SAR system will integrate the Canadian provided SAR repeater into GPS IIIF beginning no earlier than SV 11. SAR/GPS funds were transferred to GPS III SPAF beginning in FY 2019.
