SARP-3 products

The Search and Rescue Processor (SARP-3) is one of the non-meteorological instruments on MetOp. It has been added to the payload based on inter-agency agreement (NOAA/COSPAS/Eumetsat) to guarantee continuity of the Search and Rescue System. As such the instrument does not provide a 'product' as the meteorological instruments do. Its value to the MetOp mission is to continue the search and rescue service.
