* PHASE 3D LAUNCH INFORMATION *
Phase 3D is scheduled to be launched aboard an Ariane 5 rocket November 15
at 0107 UTC from the European Spaceport in Kourou, French Guiana.
Details are being worked out for the AMSAT Launch Information Net Service
to run "live" during the launch. Houston AMSAT Coordinator Bruce Paige,
KK5DO, says the net will provide launch information and commentary via
several HF stations on various bands as well as on local repeaters.
The current schedule calls for the net to start about 15 minutes before
launch and carry through separation of P3D. Paige says the plan is to
monitor the Arianespace TV C-band satellite feed for real-time launch
information, then communicate that information via a telephone bridge.
"We are not re-transmitting the Arianespace audio to avoid possible
problems with the FCC," he explained. The telephone linkup will
include key AMSAT personnel who will add their own comments and
details to the real-time announcements.
Participating commentators in addition to Paige include newly elected
AMSAT-NA President Robin Haighton, VE3FRH, as well as AMSAT-NA Vice
President for Operations Keith Pugh, W5IU; Andy MacAllister, W5ACM;
Pat Kilroy, N8PK at the NASA Goddard Space Flight Center; launch team
second-in-command Chuck Green, N0ADI; North American Command Station
Stacy Mills, W4SM; and IARU Satellite Coordinator Hans van den
Groenendaal, ZS5AKV. Others may be added as the launch approaches.
Paige says the Houston AMSAT Net, http://www.amsatnet.com, will carry
the launch information net telephone feed on its normal net connections:
satellite (Satcom 3), local repeater and Internet RealAudio.
The Launch Information Net also will be carried by key HF stations,
led by the Goddard Amateur Radio Club's WA3NAN
WA3NAN expects to be on the air an hour prior to launch and will
re-transmit on its shuttle frequencies, 3.860, 7.185, 14.295, 21.395,
and 147.45 MHz. W5RRR at the Johnson Space Center in Texas, or its
alternates, will use 3.840, 7.279, and 14.282 MHz.
The Radio Club of Kourou, FY5KE, also has announced plans to broadcast
the Phase 3D launch on 14.315 MHz in French "and probably in English."
According to Paige, Bob Arnold, N2JEU, is planning to make the
Arianespace audio available on the Internet. Details are available
CQ Amateur Radio magazine has announced plans to offer continuously
updated coverage of the Phase 3D launch via its Web site at:
http://www.cq-amateur-radio.com. CQ Editor Rich Moseson, W2VU, says
Satellite Editor Phil Chien, KC4YER, will author a running "launch log"
in which he'll post regular updates every few minutes. CQ also will
provide links to sites featuring live launch video.
Arianespace is also planning on having a live feed of the launch coverage
starting about 15 minutes before before launch till about 45 minutes after
launch when Phase 3D is scheduled to separate from the booster stage of
the Ariane 5 launch vehicle. The coverage is scheduled to be on the
Galaxy 4R C-band Satellite, Transponder 12. An Arianspace webcast
of the launch will be available at:
The following is the estimated State Vector and Keplerian Elements
for the AMSAT Phase 3D spacecraft that were recently updated. The
vector data was computed from Arianespace orbital parameters at the
time Phase 3D is scheduled to separate from the Ariane 5 upper stage.
The Keplerian Elements were computed, in turn, from the vector.

Keplerian elements will be computed from the vector, based on changes
to the scheduled or actual launch time.

Note that "93400" is a temporary Catalog Number. A Permanent Catalog
Number and International Designator will be assigned when Phase 3D is
launched. The satellite name will also be updated with the next
sequential "OSCAR" designator.
These Keplerian elements represent a pre-launch estimate of Phase 3D's
initial orbit. The orbit will change significantly over the first year
the spacecraft is on orbit. Updates will be provided for significant
The Phase 3D launch team will be publishing a similar set of Keplerian
elements. The data provided by the launch team will be "osculating"
parameters, compatible with AMSAT command station software. The
osculating elements are the exact physical representation of the orbit
as opposed to the "mean" parameters provided in this bulletin. I
provide these mean elements as they are fully compatible with the NORAD
SGP4/SDP4 orbit propagation algorithms. Tracking software that uses
the NORAD propagators should use the "mean" Keplerian elements provided
herein for the most accurate result. Tracking software using non-NORAD
orbit propagation methods should use the "osculating" elements provided
by the Phase 3D launch team.

* ARISS NEWS *
2000-11-10 18:00 UTC: The ARISS team was informed on Friday by Mission
Control in Moscow that the crew confirmed that they had installed the
amateur radio hardware in the FGB. Several engineering test passes need
to be performed before general ham radio operations can commence. This
is a major step forward for amateur radio in human spaceflight.
