AVIATION EDUCATION DAY A SUCCESS
AMSAT NEWS SERVICE BULLETIN 332.01 FROM AMSAT HQ
SILVER SPRING, MD, NOVEMBER 28, 1999
TO ALL RADIO AMATEURS
BID: $ANS-332.01
As ANS earlier reported (ANS 318.02), Hank, N1LTV, told ANS about
the (then) upcoming Aviation and Space Education Day, a part of the
Rhode Island Rockets for Schools program. N1LTV now reports the
day was a tremendous success with many hams in attendance, both
as communicators for event coordination and as active participants.
Near Charlestown, Rhode Island more than three thousand students
gathered from several states to launch model rockets, one high
altitude balloon and a Viper-Dart sounding rocket. The rocket completed
a suborbital flight, collecting comet dust from the Leonids meteor shower.
"With crystal clear blue skies but blustery winds, the Viper-Dart
sounding rocket left the launch site," reports N1LTV, adding, "it
was right on schedule to the delight of the students."
This marked the first time a missile launched from a New England
state had reached space at approximately 60 miles up.
N1LTV noted that pictures from the event, centered around the Viper
launch can be found at the following URL:

SATELLITE LAUNCH IMMINENT
AMSAT NEWS SERVICE BULLETIN 332.02 FROM AMSAT HQ
SILVER SPRING, MD, NOVEMBER 28, 1999
TO ALL RADIO AMATEURS
BID: $ANS-332.02
If all goes well, Vandenberg Air Force Base will soon be the site
for the launch of several new satellites, including JAWSAT, OPAL,
STENSAT and ASUSAT-1.
Assi Friedman, KK7KX/4X1KX, the Deputy Program Manager of the
ASUSAT program recently talked about the satellite his team has
assembled:
ASUSAT-1 is an Amateur Radio store-and-forward digital communications
satellite centered around a 9600-baud (G3RUH style) communications
platform - with a VHF uplink and UHF downlink. "From an operating
perspective," reports KK7KX, "any Amateur Radio satellite station currently
capable of working UO-22 or KO-25 should be able to communicate with
ASUSAT-1."
Assi tells ANS that after launch ASUSAT-1 should wake up in a power
safe mode, sending a status beacon in both text and binary form. The
downlink frequency will be 436.700 MHz. The planned orbit inclination is
100 degrees, at a planned orbit altitude of 750 Km.
KK7KX also reports that a web page with initial information, a telemetry
configuration file and status updates will be completed shortly. Currently,
preliminary information can be found at:

OSCAR-11 REPORT
AMSAT NEWS SERVICE BULLETIN 332.03 FROM AMSAT HQ
SILVER SPRING, MD, NOVEMBER 28, 1999
TO ALL RADIO AMATEURS
BID: $ANS-332.03
Clive Wallis, G3CWV, reports to ANS that from last October through
mid-November -- OSCAR-11 continues its stalwart operation with
reliable signals from its 145.826 MHz beacon.
According to G3CWV, the Z-axis attitude correction counter has now
reached its limit of 1,024 - which has stopped further firing of the
magnetorquer system. This means that the attitude of the satellite is
being controlled solely by the action of the gravity boom gradient.
The current rotational period is -242 seconds (0.248 revs/minute)
compared with the usual period of 350 seconds (0.171 revs/minute).
OSCAR-11 ground control action to reset the counters is expected
in the near future.
The battery voltage during daylight passes has remained consistently
high. The average value observed was 13.9 volts, with a range of 13.8
to 14.0 volts.
Internal temperatures have risen by about one degree during the
reporting period (7.4C and 5.6C for battery and telemetry
electronics respectively).
The operating schedule is unchanged with the ASCII bulletin currently
a static message, detailing modes and frequencies of all the Amateur
Radio satellites.
The mode-S beacon is transmitting an unmodulated carrier. The
beacon is a useful test source for those testing mode-S converters
prior to the launch of P3-D. Clive asks that any reports of reception on
2401 MHz are welcome. Please e-mail Clive at: g3cwv@amsat.org.
OSCAR-11 listeners may be interested in visiting the G3CWV web site.
The site contains details of hardware and software required for
capturing data and decoding ASCII telemetry from the satellite. Also
included are some audio files that are examples of each type of data
transmitted by OSCAR-11.

SILVER SPRING, MD, NOVEMBER 28, 1999
TO ALL RADIO AMATEURS
BID: $ANS-332.04
ANS news in brief this week includes the following:
** Randy, N7SFI, sent ANS projected orbit data for the JAWSAT
launch. The scheduled liftoff is currently set for 02:22 UTC on
December 8, 1999. The launch window is from 02:12 to 02:32 UTC.
Epoch time: 99342.1084 Decay: 0.00000001

** From cellular phone satellites to the laptops that astronauts use
aboard NASA's space shuttles, the aerospace industry claims it is
ready for the year 2000. Experts say they have sorted through
critical systems, such as the ones commanding Pentagon spy
satellites, and feel confident their computers will avoid problems
from the Y2K bug. But admitting nothing is certain, they still plan on
having Y2K gurus ready to react if some unforeseen problem starts
trouble at midnight, December 31st. -Florida Today
** High flying balloons carrying science experiments (and maybe
Amateur Radio transponders?--NN0DJ) for up to 100 days are closer to
becoming reality early in the next century thanks to advanced
materials and a new design by researchers led by NASA's Wallops
Flight Facility. -SpaceDaily
** During the recent ARRL EME contest Jean-Louis, F6AGR, tried to
listen to EME activity with his AO-10 class station - with success. He
tracked the Moon and clearly heard SM5FRH and IK3MAC, also
detecting other weak signals on 144 MHz. His station consists of a
12 element circularly polarized Yagi feeding a multi-mode VHF/UHF
transceiver. -ANS
** NASA's best eyes on the universe are closed temporarily after an
equipment failure forced the Hubble Space Telescope to halt its
science work. The telescope will stay shut down until space walking
astronauts replace key components of the $3-billion telescope's pointing
system during a mission scheduled for launch in December. The Hubble
system broke down when the fourth of six gyroscopes stopped working.
Three gyroscopes are needed to keep Hubble steadily locked on stars,
planets and other targets. -Florida Today
** Shuttle Discovery's flight to the Hubble Space Telescope could be
delayed if it takes NASA longer to repair damaged electrical wires.
In addition, a new problem has cropped up, a leaky hydraulic unit that
helps steer the shuttle during launch and landing. A seal is leaking on
one of the three Auxiliary Power Units that steer the main engines
during ascent and also control wing flaps and landing gear. Workers will
replace the seal and retest the unit. -Florida Today
** China's first experimental spacecraft, part of its manned space flight
program, recently completed a short mission in space after touching
down near Inner Mongolia. Details of the flight are available at:
http://www.spacedaily.com/spacecast/news/china-99m.html. -JSP List
** JPL reports that NASA's Mars Polar Lander is healthy and on target
for a landing this December 3rd. The beefed up MPL team has spent
time testing and training for the entry, descent and landing operations
of the mission. -SpaceDaily
** The 4th Ariane 5 flight (Ariane 504) is currently scheduled to take
place from Europe's spaceport in Kourou, French Guiana, on December
10th. The launch window opens at 14:32 UTC and closes at 15:02 UTC.
Ariane 5 is entering commercial service, launching ESA's XMM, a
telescope that will study X-rays sources from the Universe. -ESA

Kevin, AC5DK, reports a possible RS-13 failure. Users of RS-13 have
recently noticed the downlink was filled with data signals. Closer
inspection suggest that RS-13 is currently unusable, with no mode-K
signals getting through and mode-A signals drowned out. AC5DK
summarizes that transmitted data signals are coming through the
transponder as evidenced by the fact that they rise and fall with RS-13's

mode-K receiver. Stay tuned to ANS for further details.
