Slow Scan TV on ISS update
By Miles Mann WF1F,
MAREX-MG News www.marexmg.org
Manned Amateur Radio Experiment
Hi everyone.
There are currently two projects on board the International Space
Station that will support Slow Scan TV (SSTV). These project are
called SuitSat and SpaceCam. The SuitSat project may be activated in
December 2005 and SpaceCam in 2006 (all dates are subject to change
without notice). The goal of this series of memos is to get the
world ready to start decoding SSTV images from Space.
Here is an excerpt from a AMSAT NEWS SERVICE, ANS-261 Sept 18.
The Suitsat amateur radio system, coupled with a school artwork
project, is planned to be installed in an outdated Russian Orlon
spacesuit.
It will then be deployed from the ISS during an Extra Vehicular Activity
(EVA, or spacewalk). This is expected to occur in the December
timeframe by
the Expedition 12 crew. The Suitsat amateur radio system will beam down
special messages and an SSTV image from within the Orlon space suit
as it floats in space. Suitsat radio system will allow hams and
students
to track the suit and decode special international messages, space suit
telemetry, and a pre-programmed Slow Scan TV image through its
specially-built digital voice messaging system and amateur radio
transmitter. As built, Suitsat will be a transmit-only capability
that will run on the space suit's battery power.

SuitSat
=======
The SuitSat project will run on batteries for 2 to 8 weeks, while it
free floats in orbit as its own satellite. The SuitSat will be
driven by a Kenwood TH-K2 transceiver and a timing controller box.
The controller will transmit a series of voice messages, telemetry
and one Slow Scan TV image (Robot 36 format).. The whole series of
messages and image is approximately 9 minutes long, and then it
repeats.
SpaceCam1:
========
The SpaceCam project will also send SSTV images from ISS, however it
will be mounted Inside the ISS and will be running for several weeks
at a time and will be able to transmit over 400 SSTV images per day
(Robot 36 format).
How to Decode SSTV from Space:
I am still working on this section and ill post an updated web page
link soon.
All SSTV transmissions will be in FM mode and will most likely be on
the 2-meter band.
This means that the Doppler frequency drift will not be much of a
problem and you will be able to use your existing 2-meter station or
a police scanner to hear and decode the signals from ISS.
If you have already have been successful in working the Packet
station or talked to the ISS crew on 2-meter voice, than you already
have most of what you need.
What's left is to connect your computer to the speaker of your radio
and some SSTV decoding software, such as ChromaPix
http://www.barberdsp.com/ or similar software.
There are many choices in SSTV software, some Free, others with more
features cost a few bucks.

So have fun, find your best setup and start practicing how to decode
SSTV on 2-meters.
