Descriptive Entry

This record unit consists mostly of records documenting the administration, operation and scientific work of the STP Baker-Nunn camera and laser-ranging stations. The majority of the files were created after the Smithsonian Astrophysical Observatory (SAO) reorganization in 1973 and maintained by the Radio and Geoastronomy Division. The records include correspondence, memoranda, reports, drawings, blueprints, plans, schematics, charts, publications, manuals, maps, and data concerning station operations; station personnel; the design of stations and facilities; satellites tracked; equipment development, especially the laser-ranging system; agreements with host nations, states, and organizations; procurement requests and property inventories; weather at stations; and general administration. Also included is correspondence of STP Manager Michael R. Pearlman; photographs and slides of stations, personnel, equipment, and facilities; and information on foreign countries where stations were located.
