PHASE 3D TESTING
HR AMSAT NEWS SERVICE BULLETIN 291.01 FROM AMSAT HQ
SILVER SPRING, MD, OCTOBER 18, 1998
TO ALL RADIO AMATEURS
BID: $ANS-291.01
The AMSAT Phase 3D spacecraft is set to undergo testing at the Orbital
Sciences Corporation (OSC) test facility in Germantown, Maryland, just
outside of Washington, DC. The satellite arrived safely in Maryland on
October 13th, transported from the Phase 3D Integration Lab in a well
padded truck.
According to Lou McFadin, W5DID, AMSAT P3D Laboratory Manager,
the spacecraft will soon be placed in Osco's thermal-vacuum (T/V)
chamber. Pre-launch vacuum testing will analyze the satellite's ability to
withstand the harsh environment of space. In addition to most of the air
being removed, the temperature of the chamber is cycled up and down
to simulate the severe heating and cooling P3D is expected to
encounter. Vibration testing is also scheduled, although that test will not
be conducted until late this year or early 1999. According to AMSAT-NA
Executive Vice President Keith Baker, KB1SF, "the exact timing of
vibration testing will depend primarily on any problems encountered with
the initial thermal-vacuum testing, and the availability of the test
facilities. Our invitation at OSC is on a space-available basis," he
explained.
Maryland-DC AMSAT Coordinator Pat Kilroy, WD8LAQ, tells ANS that
P3D will be "hidden" in the chamber for up to ten days during the
thermal-vacuum testing phase. Current plans are to broadcast P3D
telemetry in real-time during the test phase, from the chamber itself.
Local amateur stations in the Maryland area equipped to copy AMSAT
OSCAR 13 PSK 400-bps telemetry should be able decode any P3D
transmissions with little effort. WD8LAQ also said DC area AMSAT
members are also looking into providing a possible Internet link as well,
so that amateurs world-wide can see and decode the satellite
broadcasts.
Pat says the test phase is continuous. "One complete thermal cycle is
predicted to run about 36 hours," he said, and "P3D will go through five
cycles."
Pat told ANS that there may be opportunities for AMSAT members to
view Phase 3D at the Orbital Sciences Corporation (OSC) test facility.
Visitors also might get a tour of the OSC building "that is rich in history,"
WD8LAQ said.
Any requests for information on P3D during its stay in Maryland, or
viewing the OSC facility, should be directed to Pat at the following e-mail
address:
wd8laq@amsat.org.

SEDSAT-1 READY FOR LAUNCH
HR AMSAT NEWS SERVICE BULLETIN 291.02 FROM AMSAT HQ
SILVER SPRING, MD, OCTOBER 18, 1998
TO ALL RADIO AMATEURS
BID: $ANS-291.02
Dr. Mark Maier, KF4YGR, Associate Professor at the University of
Alabama in Huntsville, tells ANS the SEDSAT-1 satellite package is
complete and scheduled for launch sometime later this month.
SEDSAT-1, signifying Students for the Exploration and Development
of Space Satellite number one, was developed at the University of
Alabama in Huntsville.
KF4YGR says the launch could occur as early as October 22nd,
although the launch range also has been reserved for October 25th
and 26th, with an extension to October 27th if needed. Originally set
for a July launch, the satellite will fly as a secondary passenger along
with the Jet Propulsion Laboratory's Deep Space One mission aboard
a Delta II booster.
SEDSAT-1 will include Amateur Radio configurations for digital packet
store-and-forward, analog parrot repeater and Mode A transponders.
The launch timeline is calling for a 0700 EDT launch, followed by
second stage separation and satellite deployment some 5000 seconds
later over Hawaii. SEDSAT should begin transmitting data on 432 MHz
almost immediately after deployment.
"After many years of work, the whole team --present and past-- is ready
to see SEDSAT fly and work," KF4YGR said. "SEDSAT will be a
fascinating resource for amateur radio operations, both in
communications and science collection and dissemination."

BID: $ANS-291.03
ANS news in brief this week includes the following:
** AMSAT-NA secretary Martha Saragovitz tells ANS the AMSAT office
will be closed October 15-20th. Martha will be in Vicksburg attending the
AMSAT-NA Space Symposium and Annual Meeting. --AMSAT-BB
** Paolo, IW3QBN, President AMSAT-Italy, tells ANS they have updated
the AMSAT-Italia web site, readable in both Italian and English,
containing general information about AMSAT Italia with links to other
AMSAT sites. Also included is information on the ARISS Project, with
drawings and photographs of the first dual-band modular transceiver
prototype displayed at the Surrey meeting last July. The web site
address is http://www.amsat-i.org --Paolo, IW3QBN
** The Indian Space Research Organization announced recently that
ISRO support for Amateur Radio services on a future satellite is likely
-- if there is sufficient enthusiasm for supporting such an idea. The ISRO
said that Amateur Radio operators in India should now be thinking in
terms of transponder design. The remarks came during HamfestIndia98
held at Bangalore in early October. --Nagesh, VU2NUD
** ESA announced Europe's newest astronaut, Andre Kuipers, at the
recently held Netherlands Space Expo. Kuipers, a medical doctor from
Amsterdam, joins the other astronauts that make up the European space
corps. He will begin training to qualify for future missions onboard the
International Space Station. --ESA
** The Solar and Heliospheric Observatory (SOHO) spacecraft is
performing above expectations since control of the spacecraft was
recently regained. Recommissioning activities for the numerous
scientific instruments are continuing and will persist through the
remainder of October. SOHO images of two comets that recently
impacted the sun are available at the following NASA URL:
http://umbra.nascom.nasa.gov/comets/SOHO_sungrazers.html
--ESA, Kevin, WB5RUE
** The Central States VHF Society conference committee has
announced plans for its 1999 gathering, to be held in mid-July at
Cedar Rapids, Iowa. More information is available at the CSVHF
Web site -- http://www.csvhfs.org/. --Paul, W0UC
** Pictures from the recent Western States Weak Signal Society 1998
Gathering can be seen at http://www.amt.org/WSWSS'98/Default.htm.
--WSWSS Reflector
** A group of Amateur Radio operators in Germany are looking for
stations in the eastern U.S. who have both power and antenna array
available for direct transatlantic tests on 144 MHz (not via EME or
satellite) during 1999. If interested, e-mail Achim Breuer at
achimb@koan.de. --NN0DJ
** Solar-system specialists from around the world met this week in
Madison, Wisconsin, for the 30th meeting of the American Astronomical
Society's Division for Planetary Sciences. Recent imaging results from
the Hubble Space Telescope and Galileo orbiter will be presented that
reveal impressive new details about outer solar-system worlds.--Sky
and Telescope News Bulletin
** An iceberg 92 miles long and 30 miles wide has broken off from the
Ronne Ice Shelf in Antarctica. Spotted by satellite, it has been given the
name A-38, based on its location. Scientists believe that icebergs
breaking off from the main ice mass may be a product of global warming.

The PBBS is running a Kantronics KPC-9612 + V.8.1 TNC. The
commands are similar to most PBBS and BBS systems.
MIREX has announced an on going APRS School Days Test. MIREX is
allowing schools to use APRS for position and status reports via R0MIR.
Non-school stations are asked to refrain from using APRS type
transmissions or beacons via R0MIR.
Scott, WA6LIE, recently posted a complete set of instructions on how to
work the Mir space station on the SAREX reflector. Copies of the
instructions are available from Scott by e-mail at wa6lie@juno.com, or
by packet at wa6lie@wa6lie.#wcca.ca.usa.noam.
Bob, WB4APR, asks operators to please NOT establish station-to-
station connections via Mir -- as it is very inefficient. Bob suggests
sending UI packet frames instead, saying that it is much better for
everyone AND many stations can then complete a normal QSO
during a Mir pass.

have all been reported by a number of stations.
No official word from the satellite controllers has been received.
ANS recommends monitoring each satellite carefully to determine the
transponder in operation and which mode it is operating in.
Cristi, YO3FFF, reports working throughout Europe via RS-13 mode K.
Bill, K6AKO, reports he has not heard the RS-12 beacon for some

AO-27 TEPR States are currently:

This means AO-27's transmitter turns on 18 minutes after entering the
Sun and stays on for 18 minutes. AO-27's transmitter is turned off at all
other times during the orbit. N4USI reminds stations that this happens
on every orbit, approximately 14 times a day. The current TEPR
settings will cause the satellite to be on during the daytime at northern
latitudes.
