The Public Radio Satellite System (PRSS) is the interconnected satellite-distributed network managed by NPR (National Public Radio), and used by NPR, Public Radio Exchange (PRX), and American Public Media (APM), as well as independent public radio program producers, to distribute programming via satellite to public radio stations across the United States.

The PRSS is maintained by NPR's Distribution division at their Network Operations Center (NOC), located at NPR's headquarters in Washington, D.C.^[1] A backup NOC is located at Minnesota Public Radio's facilities in St. Paul, Minnesota, in the event of a catastrophe or other situation that would occur at the main NOC's location in Washington. The NOC oversees and monitors all elements and operations of the PRSS system, from outgoing feeds from NPR, APM and PRX, and incoming feeds from member stations. The Washington NOC is also a primary entry point station in the Emergency Alert System.
