Proposed new concepts for an advanced search and rescue satellite systemMethods of reducing the forwarding time from COSPAS/SARSAT (Space System for Search of Distressed Vessels/Search and Rescue Satellite-Aided Tracking System) satellite passage until a location is supplied to the search and rescue (SAR) forces are studied. It is shown how supplemental use of geostationary satellites or institution off-polar ground stations can reduce the time delay from 62 min to 7 min. The tradeoff between the two approaches is their cost and complexity versus time delay reduction. Sample systems are developed here in order to examine the tradeoffs.
