ISS Amateur Radio Status: January 16, 2006

International Space Station ARISS SuitSat project

By Miles Mann WF1F,

MAREX-MG News   www.marexmg.org
Manned Amateur Radio Experiment

ARISS to activate a new hand launched educational
satellite project from
the International Space station.  The new educational
experiment is
called SuitSat.  The SuitSat project is onboard the
International space
station and is being prepared for activation very
soon.  The SuitSat
project has a tentative activation date of February 2,
2006.  The
SuitSat activation will take place during the ISS crew
space walk.
SuitSat will be a hand launched by the ISS crew during
the SpaceWalk.  

     Since we have just determined that the batteries
in SuitSast may last 
only a few days, suggest prepare now to receive the
1st transmissions so as 
not to miss out on this Historical event !!!

What is SuitSat:
In short, the crew will toss an Old spacesuit out the
airlock and let
fly away as its own satellite.  The Space Station crew
have attached an
Amateur Radio beacon transmitter to the spacesuit. 
The SuitSat project
as it is called will broadcast telemetry and voice
messages to earth for
as long as the batteries last.  Anyone with a simple
FM receiver or
police scanner should be able to  hear the signals
from SuitSat as it
orbits around the earth 15 times a day.

For more specific details on the SuitSat project,
please review the
AMSAT and related links below.

SuitSat project Duration:
The Reason it is important for people to get ready to
Monitor the
SuitSat project is because this is a short duration
experiment.  This is
the first version of this type of project, and it will
be running on
Batteries only. The current expected life of the
SuitSat project is
approximately 2 to 6 days.  If you delay in setting up
your station you may miss out on this educational

Voice Telemetry:
The SuitSat project will be transmitting on 145.990
MHz FM  and will 
consist of:
Voice Telemetry, giving Mission Time, Suit Temperature
and Battery
Voice Greeting messages in multiple languages
One SSTV image
The whole process will repeat every 9 minutes until
the batteries
It is recommended that you have an audio recorder
handy to record the
telemetry information.  The ARISS team may be
collecting some of the
data from individuals to help monitor the status of
the project.

Schools and Science:
School systems with existing out side VHF antennas or
the ability to set
up a temporary out side receive antenna are welcome to
listen in and
collect telemetry data.  The students will enjoy
listing to the voice
telemetry and tracking the position of the unique
satellite.  They may
even hear one of the ISS crew talking to amateur radio
stations on
145.800 MHz FM.

SuitSat Transmitter:
The SuitSat transmitter is a small hand held radio,
similar to a WalkiTalki.  The Kenwood TH-K2 will
transmit a 1 watt FM signal from SuitSat. The current
frequency for SuitSat is 145.990 FM Downlink only
(There is no uplink for this satellite).  With a
simple out side antenna and a simple VHF receiver or
police scanner, you should be able to hear SuitSat
when the satellite passes over your state. 

ARISS is also planning on using the Kenwood D700
Transceiver on ISS to
Rebroadcast the SuitSat signal on 437.800 MHz FM. 
This will allow you
to hear SuitSat while ISS is in range of your station.

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. 

SSTV (Slow Scan TV ):
SSTV is a way Amateur Radio stations send JPG still
images around the
world.  We use an audio format we call SSTV.  The
SuitSat project will
transmit Telemetry, Pre-Recorded Voice messages and
one SSTV image.  The
whole process will repeat approximately every 9
minutes. (Robot 36

What's left is to connect your computer to the speaker
of your radio and
some SSTV decoding software, such as ChromaPix
or similar software.
Here are just two of the many Share-Ware SSTV
applications on the
market.  There may be many more.

There are also many High quality pay software
applications that offer
many more features, such as multiple windows that
allow you to
simultaneously receive an image while preparing your
next image that you
want to transmit.

Until we meet again

Note to SAREX and AMSAT-BB.
Since the SuitSat project encompasses both a Free
floating unmanned
satellite and is being hand launched from a Manned
satellite, there will
be some double postings regarding the SuitSat project
on both the SAREX
and AMSAT-BB mailing lists.

If you are not currently on the SAREX list, you may
want to check the
www.AMSAT.org link to sign up for both so you do not
miss the additional
projects coming this year, and early 2006.
