Apologies for cross-postings, as some of you already receive our update notices. Since this was a major reorganization and several new features were added, I wanted to make sure that anyone who might find the Database useful knows about it. =================================================== The Union of Concerned Scientists* Satellite Database is a free, comprehensive, easy-to-use repository of information on active satellites. The database is a research tool for specialists and non-specialists alike. It contains 24 types of data for each satellite, including: technical information (orbit, mass, power, launch, expected lifetime), what the satellite is used for; and who owns, operates and built the satellite. We have just updated the satellite database Web page with additional support material, including a Satellite Quick Facts feature that provides key facts about the satellite population. The Database and the Quick Facts are updated quarterly. The database is in Excel format and can be downloaded at www.ucsusa.org/satellite_database. A new version of the UCS Satellite Database, which includes launches through January 1, 2009, has been posted. There are currently 905 active satellites in the database. The Database page has been newly organized for easier navigation, and it has several new features, including some analysis: * a "Satellite Quick Facts" box, giving current satellite counts, updated quarterly, and * a "Quick Facts & Analysis" page, explaining the derivation of the Satellite Quick Facts and answering some more in-depth questions, updated occasionally Also new to the Database page are: * a "Quick Guide to Using the Database," a how-to for several basic database tasks * a "Featured Satellite," detailing one of the interesting active satellites in the database, updated quarterly * a link to the new "Space Age Trivia" page, highlighting interesting facts about space, past and present, updated quarterly The other changes to this version of the database include: * a reorganization of the orbital information into columns with "Class of Orbit," e.g., LEO, and "Type of Orbit," e.g., Sun-Synchronous. All GEO longitude information has been moved to the column "Longitude of GEO" * The addition of 20 satellites * The deletion of 14 inactive satellites * The addition of and corrections to some satellite data * The updating of the orbital information for the GEO satellites We have incorporated your corrections and suggestions as we were able, and continue to welcome your comments. Please do let us know what you think of the new site!
