SPACEWARN Bulletin Number 458


C. Spacecraft Particularly Suited for International Participation: Category I


Spacecraft with essentially continuous radio beacons on frequencies less than 150 MHz, or higher frequencies if especially suited for ionospheric or geodetic studies.("NNSS" denotes U.S. Navy Navigational Satellite System; an asterisk [*] indicates updated/new information since the last issue.) SPACEWARN would appreciate suggestions to update this list. SPACEWARN appreciates the updates in this section supplied by G.E. Perry, Cornwall, U.K., and Piero Beni, IROE-CNR, Firenze, Italy.
