AMSAT NEWS SERVICE
ANS-358
ANS is a free, weekly, news and information service of AMSAT North
America,
The Radio Amateur Satellite Corporation. ANS reports on the
activities of a
worldwide group of Amateur Radio operators who share an
active interest in
designing, building, launching and communicating
through analog and digital
Amateur Radio satellites.
Please send any amateur satellite news or reports to:
ans-editor@amsat.org
In this edition:
* Multiple Amateur Satellites Deployed From Shuttle
* GO-32 PBBS Operational
* GeneSat-1 Continues Operations
* ARISS Status - 18 December 2006

ANDE, RAFT and NMARS were deployed from the Space Shuttle on 21 December
2006.
RAFT and NMARS have a very high spin rate. NMARS is spinning at at least
60 RPM and RAFT at maybe half that. This will make getting a complete
1 second packet difficult due to fading on linear antennas.
The Naval Research Laboratory science mission of ANDE is to measure the
density of the upper atmosphere by precise tracking of the orbit decay
by the
Maui Laser Ranging Tracking Station. The Comm system provides
important
telemetry on the attitude and temperature of the spacecraft.
RAFT carries a
216.98 MHz receiver/transmitter to demonstrate
self-location techniques when
it flies through the Space Surveillance
Network radar fence across the
southern USA. When this experiment is
activated, users will hear a 1 second
ping when it flies through the
fence.
ANDE and RAFT also carry packet radio communications systems and join
with
other US Naval Academy APRS digipeating satellites such as PCSAT-1
and
PCSAT2. ANDE and RAFT will respond to the path alias of APRSAT and
ARISS.
This is so that users do not have to reconfigure their path
between
satellites or between their ISS groundstation. The following
frequencies are
used by these two spacecraft:
* ANDE Side A: 145.825 Digipeater up/downlink 1200 baud packet
* ANDE Side B: 145.825 downlink (backup to side A only)
* RAFT System: 145.825 Digipeater up/downlink 1200 baud packet
* RAFT PSK-31: 28.120 HF PSK-31 uplink -downlink on 145.825
Much more information about these satellites is available on the ANDE,
RAFT,
NMARS, & FCAL Operations web site.

Techsat1b/GO-32 PBBS services had been suspended due to a special test
and to
maintainance needs on 25 November 2006. With the maintainance
and testing now
complete, GO-32 returned to operations on Thursday
morning 21 December 2006.

GeneSat-1 Continues Operations

The GeneSat-1 mission is proceeding very well. Biology data shows
definite
growth. Payload temperature control is doing a good job of
holding the
median payload temperature close to 34 deg C (the latest
data shows median
payload temp of 33.42). The 2.4 GHz communications
link is functional and
supporting the required level of procedural
execution by the ops team. So far
nearly all commanding has been done
in the very early morning hours, over
time the Ops Team will also be
interested in assessing how time-varying (and
most likely directional)
2.4 GHz noise affects the command link (e.g. how 2.4
GHz wireless noise
increases during normal working hours)
The 70cm beacon downlink is excellent although the frequency has shifted
down
to about 437.0645 MHz. So far over 7100 beacon packets have been
submitted
by Amateurs world-wide.
The GeneSat team is also happy to report the winner of the GeneSat First
Contact Prize for the amateur radio community: Ralph Wallio, WØRPK.
Ralph
successfully decoded 5 beacon packets at approximately 13:44:28
UTC on 16
December 2006, which was about 85 minutes after GeneSat
deployed from the
PPOD. Ralph is located in Iowa.
Additional information about the GeneSat-1's on-going mission is
availble at http://www.genesat1.org/

1. Swedish School Contact Successful
On Sunday, December 17, students attending Thunmanskolan in Knivsta,
Sweden
spoke with Swedish astronaut Christer Fuglesang, KE5CGR/SA0AFS,
on board the
ISS via the telebridge station VK4KHZ in Australia.
Fuglesang was able to
answer 13 questions posed to him by thirteen
students. Audio was fed to the
Echolink AMSAT (101 377) and JK1ZRW (277
208) servers and to IRLP Discovery
Reflector 9010. Fifty connections
from 12 countries were made to Echolink,
including 5 simplex and 3
repeater nodes. Eight stations connected to IRLP
from Canada, U.S.A,
and Sweden; 25 listened to the audio as it was streamed
on the
Discovery website. The audio was also webcast courtesy of Verizon
Conferencing.
2. Upcoming School Contact
An Amateur Radio on the International Space Station (ARISS) contact is
planned
for the Kashiwabara Community Center in Sayama, Japan on
Wednesday, December
27, at 12:22 UTC. Kashiwabara Community Center will
plan and support this
childrenâ€Ös event with the two area schools:
Kashiwabara Elementary school and
Kashiwabara Junior High school. The
children will be taught about the ISS,
space and amateur radio, and
will take a field trip to visit the Japanese
Aerospace Exploration
Agency (JAXA). Members of JAXA will also be invited to
the event.
3. Training Status
On Thursday, December 14, astronaut Tim Kopra and future space
participant
Charles Simonyi took and passed their amateur radio license
exams. In
addition, Simonyi received training on the Kenwood radio and
Amateur Radio on
the ISS school operations.
4. ARRL QST Articles on ARISS
The American Radio Relay League (ARRL) ran several stories covering
Amateur
Radio on the International Space Station (ARISS) related
activities in the
January issue of QST. A bullet item in the monthly
list of touted Amateur
Radio accomplishments described the discussion
about SuitSat-2 by the ARISS
Team at the ARISS Annual Meeting in San
Francisco (page 12).
A letter to the editor was run from a person who upon learning about
ARISS,
decided he wanted to become a ham radio operator in order to
talk to
astronauts. He succeeded in studying for and passing his ham
radio exams,
and was very lucky (and excited!) to speak with Bill
McArthur. His letter
was written to thank Bill for his time spent
doing outreach to the public
while chatting via ham radio (p. 24).
A story was run about AMSAT's Annual Symposium describing McArthur's
excellent talk at the symposium banquet. The story included his photo
(p. 75).
5. Thomas Reiter Active on Voice
On Monday, December 11, Thomas Reiter was active on the Amateur Radio on
the
International Space Station (ARISS) radio. Reiter made several
contacts with
stations in Norway, the Netherlands and the U.K.

In addition to regular membership, AMSAT offers membership in the
President's
Club. Members of the President's Club, as sustaining donors
to AMSAT Project
Funds, will be eligible to receive additional
benefits. Application forms are
available from the AMSAT Office.
