National Defense is reporting that the Air Force is building two “Polar Scout” SAR satellites for the Coast Guard, expected to be launched this year.
These satellites, or “cubesats,” are capable of detecting transmissions from emergency position indicating radio beacons (EPIRBs), which are carried on board vessels to broadcast their position if in distress. The Coast Guard will deploy the cubesats in cooperation with the Department of Homeland Security (DHS) Science and Technology Directorate’s Polar Scout program, the Air Force Operationally Responsive Space Office, and the National Oceanographic and Atmospheric Administration (NOAA).
These two satellites will only provide intermittent coverage of EPIRB signals from the polar regions so more satellites may follow.
This appears to be first fruit of a growing cooperation between the Coast Guard’s R&D Center and the Air Force Research Laboratory which has been formalized by a recent Memorandum of Understanding (MOU) signed by the heads of the two organization on April 12, 2018.
