SuitSat-1 deployed

SuitSat-1 deployed from ISS at 23:02 UTC, 3 Feb 2006.


SuitSat-1 Downlink Sequence

Now that you understand the specifics, what can you expect when SuitSat
is over your area? To save SuitSat power and to maximize the time that
SuitSat is operational, 30 second pauses have been included between each
of the voice messages. So the sequence will be as follows:

1. SuitSat Voice ID (5 seconds)
2. International voice message, Suit Voice
3. Telemetry, or SSTV Image (15-45 seconds)
4. 30 second pause 
...and repeat

The international message order will be as follows:

1. Voice Telemetry
2. Russian Message
3. Europe Student Messages (Spanish and German)
4. Bauman Institute Message (Russian)
5. Canada Student Message (French)
6. Mr. Alexandrov Message (English)
7. Japan Student Message (Japanese)
8. USA Student Message (English)
9. SSTV Picture

Subject: How to Hear SuitSat, and save telemetry [amsat-bb:90764]
From   : Miles Mann / WF1F, MAREX-MG,
Date   : Feb 8, 6:08 JST, 2006

ISS Amateur Radio Status: February 6, 2006

Topics: SuitSat How to hear it.

By Miles Mann WF1F,

Manned Amateur Radio Experiment

SuitSat-1 was launched on schedule last Friday
February 3rd 2006.  Due to an antenna system problem,
the 500 milliwatts of transmitter power is not making
it all the way to the antenna.  The exact cause of the
power transmitter power loss is not known.  As a
result it is very difficult to copy the signals coming
from SuitSat-1.  The SuitSat-1 transmitter and
controller are still working.  The voice messages,
Telemetry and SSTV image is still being sent every 9
minutes on a repeating cycle.  The down link is just
too weak for most station to copy.  If you do have a
tracking antenna system then we would like to hear
from you if you are able to get some reliable
telemetry information from SuitSat.

Specifically what we need is the following:

Temperature: Every few minutes the voice will speak the temperature
Battery Voltage: Its on a 28 volt scale.
Date and time UTC you heard this data.
Location:  where you are when you head this data.

At the beginning of each 9 minute cycle, the SuitSat-1
will ID and then speak the Mission time, Temperature
and voltage in this format:
This is SuitSat-1 RS0RS
Mission time is:
The temperature is: 21 degrees Celsius
The Battery voltage is: 27.4 Volts

If you hear CW, get ready to decode SSTV.  The order
will be a DTMF tone, followed by the CW ID and then
SSTV.  This is also a good time to listen for the
System Telemetry.  The Telemetry comes right after
the SSTV image.  Then the whole process repeats.

What you Need to Hear SuitSat-1:
Antenna, High gain, 10+ dBd at least.
(Circular polarized antennas work better)
AZ/EL Rotor system
Mast Mounted Preamp
Very close pass, better than 40 degrees

How big is my antenna in Gain?
Just count the number of dipole elements that are
one/half wave long
1 = 0 dBd
2 = 3 dBd
4 = 6 dBd
8 = 9 dBd
16 = 12 dBd

I notice that the temperature rises slowly,
and the battery voltage decreases slowly.
SuitSat-1 maybe gain steadily upon the earth.

I do not normally post "not heard" reports, but considering the drop in
voltage noted by Richard, N2SPI and the fact that Bob, VE6BLD has almost
always heard SuitSat, I am regretably posting this report from VE6BLD.

Hello AJ and all...
Well I never heard a sound from suit sat during the 11:28 pass at 24 degrees
elevation. My next pass was at 67 degrees and still not any audio at all!!
I think Suit Sat has expired as far as audio transmisions are concerned!!
If it has indeed dropped in voltage below a critical 9 volts then all I can
say is it has been a very exciting experience to have had the oportunity to
receive so many clips of audio over the last two weeks. I would like to thank
everyone involved is getting Suit Sat operational. It has been a great
experience and a pleasure to pass on the reception reports I have received.!!
73 to all
