Getting Ready for ARISSat-1/RadioSkaf-V Operation

Here are some reminders to help you get your station ready for
ARISSat-1/RadioSkaf-V
operation. Your 2-meter FM radio or HT will work well to receive the FM
voice messages
and SSTV on the
145.950 MHz downlink.

You will need a SSB-capable receiver to copy the BPSK telemetry beacon, the
CW beacons,
and the linear transponder passband.

Read about the details ...

145.950 MHz FM Downlink:
------------------------
FM transmissions will cycle between a voice ID as RS01S, select tele- metry
values, 24 international
greeting messages in 15 languages and SSTV images. One of the messages will
be a conversation
between Yuri Gagarin and ground control.

435 MHz - 145 MHz Linear Transponder:
-------------------------------------
The linear transponder will operate in Mode U/V (70 cm Up, 2m Down).
It is an 16 KHz wide inverting passband and the convention will be to TX LSB
on the 435 MHz
uplink and RX USB on the 145 MHz downlink. This mode is designed to work
with low power
transmitters and omni antenna.

145.919 MHz/145.939 MHz CW Beacon:
----------------------------------
The CW transmissions will be callsign ID RS01S, select telemetry, and
callsigns of people actively
involved with the ARISS program.

145.920 MHz SSB BPSK-1000 Telemetry:
------------------------------------
The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil
Karn, KA9Q to be
readable in low signal level conditions.
The BPSK data will transmit satellite telemetry.

The ARISSat-1/RadioSkaf-V BPSK-1000 downlink is transmitted in SSB mode on
145.920 MHz. When
the CW2 beacon on 145.919 MHz is active this indicates that the BPSK-1000
format is being transmitted.
If the CW1 beacon on 145.939 MHz is active this indicates the backup of
BPSK-400 format is being transmitted.

Transmitting at 100 mW, both BPSK rates include Forward Error Correction
(FEC) and it is expected that
modest quarter-wave antennas with low-loss coaxial cable will provide
sufficient signal strength for
decoding and display by the ARISSatTLM software.

Call For Articles - Brief Author's Guide to the AMSAT Journal

You are invited to share your amateur radio in space ideas and experiences
with fellow
satellite operators.
The AMSAT Journal, a bi-monthly publication of AMSAT-North America, brings
you the
latest information in satellite mission planning, satellite- related
hardware design and
construction, satellite-related
sof- tware design and implementation, and amateur radio earth station
construction.

There are plenty of opportunities for you to share your ideas and experience
across all
levels.
Did you homebrew a successful antenna? Which setup did you use for your
first satellite
con- tacts? A brief write-up and photos are appreciated by everyone!


Do you have ideas about future amateur radio space missions? Can you
describe unique
aspects of a particular orbit and the equip- ment needed to make it work?
Simply type out
your ideas on your computer and send them in. Let the AMSAT Journal
editorial team do the
clean up and formatting for you.

Its easy to send your article to the AMSAT Journal e-mail box via
journal@amsat.org.
There is no need to do any special formatting on your submission because
the final layout
format is driven by the magazine's typesetting software. All you need to
include is:

+ Your text in MS-Word or plain text format Graphics saved in separate
+ files (jpg, gif, tiff)

(Actually, an MS-Word file with embedded graphics is the most diffi- cult
format to typeset.)

If you have any questions, or need some help feel free to contact the
editors at the AMSAT
Journal at journal@amsat.org. One of us will get back to you as soon as we
can.

Reminder: The DARA Matching Gift Challenge

The Dayton Amateur Radio Association (DARA) has announced a fund raising
challenge
for AMSAT whereby they will match on a 1:3 basis up to $5,000.00 for
donations made in 2011.
That is, for every $3.00 that AMSAT raises, DARA will provide $1.00 up to a
maximum of $5,000
donated by DARA.

AMSAT kicked off the fundraising campaign at the Hamvention, where donations
began count
against this goal. Please consider making a donation to AMSAT at Hamvention
or anytime this
Spring as we strive to meet this goal.

We appreciate DARA's support for AMSAT and see this as an opportunity for
donors to increase
the impact of their donations by taking advan- tage of this matching
program.

Amateur Radio on the International Space Station (ARISS) Status Report June
27, 2011

1. Japanese Contact Successful

On Tuesday, June 21, an Amateur Radio on the International Space Station
(ARISS) contact was
held between Nankan 4th Elementary School in Tamanagun, Kumamoto, Japan and
on-orbit
astronaut Satoshi Furukawa, KE5DAW. There was a delay in making contact, but
once established,
the students got in nine questions. This unique activity supplemented lesson
plans about amateur
radio technology and the International Space
Station mission. An audience of approximately 100 attended the event
which was covered
by 5 newspapers and 5 television stations, including NHK (Japan Broadcasting
Corporation).

2. ARISS International Team Teleconference Held

The monthly ARISS International Team meeting was held on Tuesday, June 21.
Topics covered
included the upcoming ARISS Face to Face meeting in October and a status on
the ARISSat-1
satellite, designated KEDR in Russia. Minutes have been
posted: https://www.rac.ca/ariss/arisstel2011-06-21.htm

3. News of U.S. ARISS Proposal Process Distributed

The NASA EXPRESS message sent on June 16 included an item on ARISS contact
opportunities
for U.S. schools using the new proposal process. Also made aware of these
opportunities were
other U.S. education organizations such as Solar System Ambassadors, Space
Grant Community,
INSPIRE, WISH, Endeavor Fellows and the Museum Alliance.

4. Astronaut Training Status

Don Pettit, KD5MDT, and André Kuipers, PI9ISS, were given an ARISS preflight
session on June 22.
The two astronauts hope to participate in ARISS contacts during their flight
with Expedition
30 which will launch in November 2011.

5. ARISS Items in ARRL Letter

The American Radio Relay League (ARRL) ran two ARISS items in its June 23
ARRL Letter.
The first story is about the astronauts who recently passed their amateur
radio Technician exams
and were issued call signs. This piece is titled "NASA Astronauts and
Astronaut Candidates Earn
Amateur Radio Licenses." The second item is titled "Field Day from Space:
International Space Station Could be Active for ARRL Field Day." Both
stories may be viewed at:
http://www.arrl.org/arrlletter?issue=2011-06-23

6. AMSAT Covers ARISS Proposal

The AMSAT (Radio Amateur Satellite Corporation) News Service June 26
bulletin
(ANS-177) included another announcement about the new ARISS proposal process
for U.S. schools.
"July 15 Deadline to File ARISS Contact Proposals" may be found here:
