Weather Satellites

GAO reviewed the United States' two separate, but similar, polar-orbiting meteorological satellite systems to determine if the two systems could be combined to eliminate duplicative practices and overlapping functions, and continue to provide necessary services to the systems' users.

GAO found that: (1) national policy supports the convergence of polar meteorological satellite systems; (2) convergence is technically and operationally feasible, since both systems collect similar types of data and have common features; and (3) the federal government could save several million dollars by combining the two systems of four satellites to one system of three satellites, eliminating areas of duplication, using multiyear procurement contracting, and purchasing parts in larger quantities. GAO noted that: (1) the National Oceanic and Atmospheric Administration (NOAA) and the Air Force independently took steps or planned actions that would further separate the satellite systems; and (2) the systems now have fewer interchangeable electronic components. GAO also found that alternative ways of combining the systems include: (1) integrating sensors; (2) redesigning the existing four-satellite system into a three-satellite system with a mix of sensors; and (3) creating a hybrid system consisting of three existing satellites. GAO concluded that the Department of Commerce office responsible for coordinating all federal meteorological programs, except meteorological satellites, could expand its operations to include these satellites and, thus, assist in the convergence process.
