PHASE 3D LAUNCH DATE UNKNOWN
HR AMSAT NEWS SERVICE BULLETIN 172.01 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 21, 1998
TO ALL RADIO AMATEURS
BID: $ANS-172.01
As announced earlier this week via the AMSAT-BB, the Phase 3D satellite
will not be launched on the third test flight of Ariane 5. The bad news
reached Karl Meinzer, DJ4ZC, Phase 3D Project Leader and AMSAT-DL President
on Monday, June 15th. He immediately informed the P3D Project workers of
the unfortunate news.
AMSAT-NA President Bill Tynan, W3XO, had the following explanation for the
decision:
"It is important to point out that the decision was actually made by
Arianespace, not ESA. As everyone should know by now, ESA is the European
Space Agency. It is similar to NASA in the United States except that it is
multi-national. Arianespace is the organization set up to market Ariane
launches. So, naturally, its prime interest is money. Because of the
failure of the first Ariane 5 test, A-501 in June of 1996, and the
less-than-expected performance of the second flight, A-502 last October,
all concerned have been understandably anxious to complete a fully
successful test as soon as possible. Arianespace cannot begin to sell
Ariane 5 launches until a successful test actually takes place. The failure
of 501 and the lower-than-expected performance of 502 have caused an
extension of the program and hence have increased the cost of the
development phase. ESA has been anxious to recoup some of these additional
costs. As a result, they asked Arianespace to try very hard to find a
paying customer for A-503. A figure of somewhere around $35,000,000 was
mentioned. This is about half of the amount usually paid to launch a
present-day commercial satellite on an operational launcher. The lessor
amount is indicative of the fact that Ariane 5 is not yet fully
operational. ESA even signaled a willingness to delay the flight until a
suitable customer could be found. This shows how serious they were in
wanting to recoup some of the financial losses they have suffered as a
result of the delays and problems that have befallen the Ariane 5 program."
"Arianespace, apparently in order to get the A-503 flight off as soon as
possible, and so that they could begin to sell future Ariane 5 launches,
agreed to pay ESA some $40,000,000 in order to control the payloads on the
mission and get A-503 launched as soon as possible. It is not known at this
time what Arianespace will chose to put on the 503 flight; it may even be a
dummy satellite of some sort. The bottom line is that Phase 3D will not
ride on Ariane 503," Tynan said.
"While we are disappointed, Tynan continued, "crying and gnashing of teeth
never accomplishes anything." He emphasized that "AMSAT is taking steps to
complete the testing of Phase 3D and have it ready for any launch that we
might be able to obtain," adding, "naturally, ESA and
Arianespace are still prime candidates for our presentations."
Tynan emphasized that Phase 3D was designed and built "with the then very
real prospect of a launch on an Ariane 5 vehicle." It was later determined
that with an appropriate adapter, it could also be accommodated by an
Ariane 4 launch vehicle. "But, because it was built to go on an Ariane, it
just can't be put on any rocket that's going up," said Tynan. Continuing,
he noted that Phase 3D is a "rather large spacecraft and also quite
massive, in the order of 600 kilograms or about 1200 pounds when fully
fueled. As such, it requires a launcher with a large volume under the
shroud and a launch vehicle with substantial performance."
"The orbit that the launcher puts us into is also very important", Tynan
continued. "Generally a geostationary transfer orbit is what we need. A
launch into a circular low Earth orbit would be much less than optimum.
Many launches, including the Shuttle, go to such LEO orbits. There are, of
course, other launchers that go to GTO besides Ariane, and we will be
looking at them. However, nothing can be promised at this time," he
concluded.
Tynan told ANS that he hopes that AMSAT-NA members, and all who have
contributed to the Phase 3D project to such a great extent, will keep the
faith and continue their support while efforts to secure a launch for Phase
3D continue. He also made it clear that AMSAT is beginning to embark on
other projects as Phase 3D is being completed. These include assisting with
a number of university satellite projects, some of which are to include
amateur transponders. Effort is also getting under way in connection with
developing amateur radio equipment for the International Space Station. "In
addition, I'd like everyone to remember that there are several satellites
preparing for launch which will carry amateur transponders," said Tynan.
The AMSAT-NA president wrapped up his statement with; "there's lot's to
keep all satellite enthusiasts occupied while waiting for the launch of
Phase 3D, which will come in time. Just because Phase 3D will apparently
not be launched this year, AMSAT is very much alive and kicking!"

SILVER SPRING, MD, JUNE 21, 1998
TO ALL RADIO AMATEURS
BID: $ANS-172.02
TMSAT-1 is now safely bolted to the RESURS-O1 #4 spacecraft at the Russian
Baikonur Cosmodrome in Kazakhstan, ready for launch at approximately 0200
UTC on the June 23, 1998. The microsatellite was recently integrated to
the RESURS housing following the completion of electrical tests. The
satellite will not be touched again except for the final battery charging
with will occur just prior to the rocket being rolled out to the launch
pad.
TMSAT-1 will stay attached to the RESURS housing until approximately 7 to
12 hours following launch, when it will be released by ground control in
Moscow. The satellite housekeeping systems will be activated during the
first few orbits after the deployment.
The satellite is scheduled for an 821-km sun-synchronous orbit.
Further information about TMSAT will be posted to UO-22 as the launch draws
near, and updates on the commissioning itself will be uploaded to TMSAT and
UO-22 following the launch.
The TMSAT-1 telemetry configuration file is available using the following
URL:

Dr. Mark W. Maier, University of Alabama tells ANS that the SEDSAT-1
satellite recently passed several tests, including an important three-axis
vibration test. For each axis an up/down sine diagnostic sweep, a body
dynamics sine test and a random vibration test was completed. Dr. Maier
reports all modes were at a constant frequency before and after the test.
A shock test is scheduled in the near future.
SEDSAT-1 will carry a Mode-L digital transponder as well as a Mode A analog
transponder. The planned orbit is 500 by 1000 km at 28.5 degrees
inclination. The satellite is now scheduled for launch on a Delta II space
vehicle sometime in October of this year. The exact launch date has not
been confirmed.
Stay tuned to ANS for further developments.

APRS EXPERIMENT DAYS ON AO-16
HR AMSAT NEWS SERVICE BULLETIN 172.04 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 21, 1998
TO ALL RADIO AMATEURS
BID: $ANS-172.04
Bob, WB4APR, reports the AO-16 command team has authorized an APRS
experiment on AO-16 to explore the use of the 1200-baud PACSAT for APRS
position/status reporting. The test periods will run each Tuesday from 0000
to 2359 UTC. APRS experimenters will uplink on 145.940 MHz FM, with a
437.0513 MHz SSB downlink. TNC's must be capable of 1200 bps Manchester FSK
transmission and RC-BPSK 1200 baud PSK reception. Non-Manchester style
TNC's can be easily modified to send and receive this style of
transmission. The May/June 1997 AMSAT Journal has full details on the
modification.
The intent of the experiment is to provide a channel for travelers and
wilderness position/status reporting (1 or 2 packets per station per day).
Bob says existing users of AO-16 need not fear a deluge of activity, since
most APRS users are already connected nationwide via VHF, UHF, HF or
Internet gateways. "Ham truckers, RV hams, offshore boaters and
cross-country mobile travelers in the wilderness may find AO-16 perfect for
their needs," reports WB4APR.
Bob says the Tucson Amateur Packet Radio organization has established a
special interest reflector for AO-16/APRS experimenters. To subscribe, send
an email message to:
listserv@tapr.org
In the body of the message, put the words: subscribe ao16aprs Your Name
WB4APR says the long term objective is daily coverage, but to test this
concept, the once a week APRS test day will gather data on the optimum
transmission rate and on the details of making the Manchester modification
on a variety of TAPR-2 style TNC's. The AO-16 command team is also hoping
the experiment may lead to developments in using digital signal processing
(DSP) to automate the reception of the PSK downlink.
Stay tuned to ANS for further developments.
