IJPS is a cooperative effort between the United States and the Europeans to share responsibility for polar satellite operations and derived products. The details of IJPS can be found in The Agreement Between the United States National Oceanic and Atmospheric Administration and the European Organization for the Exploitation of Meteorological Satellites on an Initial Polar-orbiting Operational Satellite System, signed in November 1998. IJPS will be supported by US satellites, NOAA-N and -N', in the afternoon orbit and European satellites, MetOp-1 and -2, in the mid-morning orbit. As part of the IJPS agreement, NOAA and EUMETSAT are required to support each other's operational satellite through their respective ground segments for commanding, receiving telemetry and global data, monitoring their respective on-orbit status, and exchanging data between the two polar satellite systems. In order to meet the requirements of IJPS, the NOAA Polar Ground System is undergoing numerous changes. This paper will provide an overview of several elements of IJPS with a focus on the changes to and the benefits of IJPS on the NOAA Polar Ground System.
