ISS SSTV Status





       A host of recent messages on the Sarex Bulletin Board have indicated
   the
    very strong interest from Amateur Radio Operators worldwide in receiving
    SSTV from the International Space Station.  This memo will serve as an
    update on planned ISS SSTV activity.
        As many will recall, excellent Amateur Radio SSTV pictures were
   provided
    by the Mir Space Station Crews. The MAREX-NA  Group who initiated and
  built
   the Mir System have combined with the ARISS/AMSAT/ARRL groups for the ISS
   SSTV Project.
    The Mir System employed a hardware approach.  A different system is
being
    readied for the ISS.  It is a software system called SpaceCam1.  It is
    basically an abbreviated  version of the world recognized Silicon Pixel
    "Chromapix" (CPIX) software.
        In January, 2001 a letter from ARISS/ ARRL/AMSAT groups  approved
the
  MAREX
  proposal for the above software system. Considerable  testing has already
   been done
    with  both  terrestrial and satellite setups to check performance which
    has demonstrated excellent results.
        Details of the ISS SSTV System are referenced in the following URL

      Suggested information on receiving SSTV pictures along with a picture
   of
   the screen from which the crew will be using to send us  pictures is
 shown
   in the above referenced web page.

        It is anticipated that as early as this summer the software, along
  with
    the necessary interface box to the ISS laptop,  can be readied for
   transport
   to the ISS. As referenced in the above URL, the interface box is being
   completed
    by Lou McFadin, W5DID who will be giving a talk  on this at the Dayton
    Hamvention SSTV Forum on  Saturday, May 19, 2001, starting at 10:15 AM.
        Standby and get ready for exciting  pictures from the crews of the
    International Space Station!!
