Space and Satellites

• Amateur Satellite Page
  From N7RYW -- This site provides links to a wide variety of PC software for satellite work.
• AMSAT-NA
  The Radio Amateur Satellite Corporation Web Server.
• AMSAT-UK
  The Radio Amateur Satellite Organisation of the United Kingdom.
• Basic Satellites
  An excellent introduction to satellites by Stephen Holmstead
• Current two-line element sets from the Air Force Institute of Technology:
  • NORAD two-line orbital element sets for amateur radio satellites
  • Current Two-Line Element Sets for selected satellites.
    Data source is the NORAD two-line orbital elements. These files should provide a timely means of obtaining orbital information without the need to manually enter the data.
• DOVE Satellite Decoder Program (V2.0)
  A new version of the DOVE satellite decoder program (V2.0) -- It will decode the telemetry data that comes from the DOVE amateur radio satellite. In this release are numerous bug fixes and some new graphing capabilities. It requires windows 3.1, a packet TNC and a 2 meter rig. This program is FREEWARE
• Keplerian Elements
  From AMSAT -- Keplerian elements are the inputs to a standard mathematical model of spacecraft orbits. With the "keps", the correct time, and your station location, you can compute when the satellite will be in view and where to point your antennas. See also the tutorial on Keplerian elements and the explanation of the formats used in these files.
• Nova
  Fast, accurate, and easy to use satellite tracking software from Northern Lights Software.
• Radio-Sky Publishing
  A site for amateur radio astronomers, a small but growing group of people who make radio observations of cosmic phenomena. Radio-Sky sells books and computer programs to help facilitate these efforts.
• Sat FAQ Answers
  
• SAREX information
  The Shuttle Amateur Radio Experiment (SAREX) is a long-running program to use amateur radio equipment on board the Space Shuttle to involve students in exchanging questions and answers with astronauts on orbit. More than 200 schools have participated to date. It is also used to conduct communications experiments with amateur radio operators on the ground.
• Satellite News
  
• Satellite Tracking
  A forms interface for the N3EMO orbit simulator (found at ftp://ftp.uu.net/usenet/comp.sources.misc/volume11/n3emo-orbit).
• The Small Satellite Home Page
  Provides up to date information, resources, references and links for space researchers and enthusiasts.
• SpaceNews
  SpaceNews is available via the Amateur Packet Radio Network (AMPR) and via the AMSAT-OSCAR-16 and LUSAT-OSCAR-19 "Pacsat" satellites. It is also posted to Usenet under the newsgroups of rec.radio.amateur.space, rec.radio.info, and sci.space.newsi. Archives are available via anonymous FTP at pilot.njin.net in the pub/SpaceNews subdirectory.
