    Dear visual satellite observers,
    We've finished putting together a database of all the active
    satellites, with their attributes.
    I hope that it will be useful to you.
    This database differs from others you may have used in that it does not
    contain TLEs, nor information on debris or satellites that are known to
    no longer be active. Instead, we have gathered public information on
    operational satellites so that one can obtain aggregate information
    about populations of satellites or some detailed characteristics on
    individual satellites of interest.    And it is in Excel spreadsheet
    format, in order to be easy to manipulate and search.
    I'm copying the release information below.  As part of the release, I
    was interviewed by the Associated Press, and the reporter was very
    interested in amateur satellite observing.  I sent her as much
    information as I could from the public realm.  The story is a bit
    sensationalist, but I do hope you feel you were represented faithfully.

    AP Story:
    The Union of Concerned Scientists (UCS) announces the release of the
    UCS Satellite Database, a searchable list of over 800 active satellites
    with detailed information about them. The database is free and can be
    downloaded from the UCS website. It is in Excel format, allowing users
    to easily search and sort the data. 
    The UCS Satellite Database is the only free, comprehensive compilation
    of active satellites in an easy to manipulate, commonly used database
    format.  The database uses data from publicly available sources, and its
    distribution and use are unrestricted. It will be updated quarterly. 
    The database is intended to be a research tool for specialists and
    non-specialists alike. Users can find information about a particular
    satellite; identify sets of satellites having a common characteristic,
    such as altitude or mission; and sort or aggregate data about the whole
    population of satellites. Users can quickly answer questions such as 
    *How many satellites does a given country have in orbit, and what are
    they used for?
    *How many satellites are used for military purposes versus commercial
    *Which countries have earth-observing satellites? At what altitudes do
    most satellites orbit?  
    The database contains 21 types of data for each satellite, including
    technical information about each satellite (mass, power, launch date,
    expected lifetime) and its orbit (apogee, perigee, inclination, and
    period), as well as what the satellite is used for, and who owns,
    operates, and built the satellite.  
    The database and Users' Manual can be downloaded at  We welcome corrections,
    additions, and suggestions. These can be emailed to the Database manager
    Formed in 1969, the Union of Concerned Scientists is a nonprofit
    partnership of scientists and citizens combining rigorous scientific
    analysis, innovative policy development and effective citizen advocacy
    to achieve practical environmental solutions.
