PHASE 3D UPDATE
AMSAT NEWS SERVICE BULLETIN 185.01 FROM AMSAT HQ
SILVER SPRING, MD, JULY 04, 1999
TO ALL RADIO AMATEURS
BID: $ANS-185.01
AMSAT Phase 3D Laboratory and Integration Manager Lou McFadin,
W5DID, tells ANS that a major Phase 3D milestone was recently
reached in two areas; first with the test firing of the system that will
deploy the solar panels once the satellite reaches orbit, and second,
testing of the control electronics for the 400N propulsion system.
Both tests were completely successful.
Rick Leon, KA1RHL, who built the Array Release Unit (ARU) and Liquid
Ignition Unit (LIU) electronics, and Bob Davis, KF4KSS, who constructed
the solar panel deployment mechanism, both observed the performance
of the systems as Peter Gulzow, DB2OS, programmed the spacecraft
computer using a ground station to send commands.
W5DID reports the deployment system worked flawlessly and the solar
panels were pushed to full open position. In addition, the 400N thruster
and the ATOS Arcjet test firing was also successful - all under the
watchful eyes of Dick Daniels, W4PUJ, Karl Meinzer, DJ4ZC, DB2OS
and KA1RHL.
The spacecraft has also passed a major 'on air' test under full flight
configurations. Place outside (and protected) from the Florida
environment by a large sealed tent, RF communications manager
Werner Haas, DJ5KQ, reports all RF subsystems aboard the satellite
worked nominally.
Another major event was the successful completion of the SBS (support
bearing structure) load testing. The SBS will carry the P3-D satellite
inside the launch vehicle during its ride to Earth orbit.
W5DID tells ANS that "after a few more close-out items and a spin
balance test, Phase 3-D will be ready for its final vibration and shake
test." Vibration and shake testing is currently scheduled for later this
month at NASA facilities in Washington, D.C.

STS-93 MISSION TO TEST DSP HARDWARE
AMSAT NEWS SERVICE BULLETIN 185.02 FROM AMSAT HQ
SILVER SPRING, MD, JULY 04, 1999
TO ALL RADIO AMATEURS
BID: $ANS-185.02
The next Space Amateur Radio EXperiment mission (now set to launch
July 20th) will field test a digital signal processing box NASA is looking at
to improve the quality of shuttle communications audio.
The STS-93 Mission Commander is Eileen Collins, KD5EDS. Other
hams on board include Mission Specialists Michel Tognini, KD5EJZ, and
Catherine Coleman, KC5ZTH.
NASA's SAREX Principal Investigator Matt Bordelon, KC5BTL, says the
agency's contractors have been exploring ways to make improvements
to the aging shuttle fleet. Among the possibilities was improving the
intelligibility of shuttle communications audio by using DSP. Bordelon
says "making and testing these kinds of changes on the astronauts'
communication system gets expensive and involved, so it was
decided to first try out a DSP box on the less-critical SAREX payload
aboard STS-93 to see how it performed under actual spaceflight
conditions."
"They wanted an easy way to determine if this would clean up the audio,"
Bordelon explained, "and since the SAREX Amateur Radio gear uses
standard interfaces, it was an easy match from a hardware standpoint."
Bordelon says the two-channel DSP box tailors both the transmit and
receive audio.
Students at five schools are on the list to talk to the STS-93 crew via
Amateur Radio.
STS-93 will mark the 25th time that the Space Amateur Radio
EXperiment has flown. The SAREX program is a cooperative venture of
NASA, AMSAT and the ARRL.

ISS UPDATE
AMSAT NEWS SERVICE BULLETIN 185.03 FROM AMSAT HQ
SILVER SPRING, MD, JULY 04, 1999
TO ALL RADIO AMATEURS
BID: $ANS-185.03
The International Space Station is back on its own after the recent visit of
the space shuttle Discovery to deliver supplies and logistics in
preparation for the arrival of the first crew to live on the station early next
year.
The station's systems remain in excellent shape.
Meanwhile, at the Kennedy Space Center in Florida, the multi-element
integrated test (MEIT) continues on components scheduled for launch to
the ISS next year. This test connects components on the ground via
cabling (as they will be in space) to verify they work together as well as
they do individually. Additionally, the station's robotic arm -the Space
Station Remote Manipulator System- supplied by the Canadian Space
Agency has arrived at KSC for flight processing. The first piece of truss
segment has also arrived at KSC for pre-flight checkouts.
The next shuttle flight to visit the ISS is scheduled for December
following the launch, docking and checkout of the Zvezda Service
Module living quarters this November.
ISS flight controllers in the United States and Russia began the first
scheduled full charge and discharge of the six batteries on the Zarya
module as part of a twice-yearly procedure to maintain as long a life on
the electrical storage units as possible.
This procedure is performed on each battery every six months and is the
first time to be done on Zarya's batteries.
The International Space Station is in an orbit with a high point of 256
statute miles and a low point of 237 statute miles, circling the Earth once
approximately every 92 minutes. The Station has completed more than
3,379 orbits of Earth since its launch. As it passes overhead at dawn or
dusk, the station is easily visible from the ground. Space station viewing
opportunities for locations worldwide are available on the Internet at:

SUNSAT SO-35
SunSat was launched February 23, 1999 aboard a Delta II rocket from
Vandenberg Air Force Base in California. SunSat stands for
Stellenbosch University Satellite and takes it name from the South
African university whose students constructed the payload.
The 'test' of SunSat in FM repeater mode this weekend over the
U.S. and Europe at first failed because of an on-board computer
crash. The following statement was released by Garth, ZR1AFH:
SunSat was programmed to support 'FM repeater' style operations over
South Africa, Europe, and America on Sunday, 4-July. SunSat was silent
during the South African passes suggesting that the OBC-1 computer
had crashed. When this occurs, its watchdog timer resets the computer
and satellite into a safe condition, which presently does not include
executing the uploaded diary commands that would have activated the
FM transponder.
ANS learned the satellite was (apparently) successfully reprogrammed
as the central U.S. pass Sunday afternoon yielded multiple contacts on
the FM transponder. Many stations commented on how strong the
downlink signal from SO-35 actually was. A full story on this successful
operation will be carried in ANS-192.
ANS congratulates the SunSat team on this achievement!
Bruce, KK5DO, captured the first 'FM' pass of SunSat in Real Audio and
has posted the file at: http://www.amsatnet.com
The SunSat package includes 1200 and 9600 baud digital
store-and-forward capability and a voice 'parrot' repeater system
that will be used primarily for educational demonstrations.
The satellite has two VHF and two UHF transmit-receive systems.
