AMSAT NEWS SERVICE
ANS 233
ANS is a free, weekly, news and information service of AMSAT North
America, the Radio Amateur Satellite Corporation. ANS reports on the
activities of a worldwide group of Amateur Radio operators who share an
active interest in designing, building, launching and communicating
through analog and digital Amateur Radio satellites.
AMSAT-NA is pleased to announce that recent and future development
in Amateur Radio satellites will be presented in Portland, Maine

ISS UPDATE
AMSAT NEWS SERVICE BULLETIN 233.01 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 20, 2000
TO ALL RADIO AMATEURS
BID: $ANS-233.01
ISS flight controllers in the United States and Russia continued
preparations this past week for the crew of Shuttle mission STS-106,
who will be the next station visitors. The mission, aboard shuttle
Atlantis, will open up the newly attached Zvezda living quarters module
for the first time. The Atlantis crew returned to Houston recently after
spending a week at the Kennedy Space Center preparing for the
September mission to the station. Atlantis is to deliver several thousand
pounds of equipment, food and supplies to the orbiting outpost to prepare
it for the arrival of the first resident crew in November
Meanwhile, the flight of shuttle Discovery to ISS in October may be
slightly delayed, NASA officials said recently. The possible delay
is tied to a piece of equipment the shuttle is to deliver to the station and
not to the shuttle itself, which is having no problems. A decision on a
possible delay will be made shortly. Discovery is currently scheduled to
lift off October 5th from the Kennedy Space Center. Its main cargo will
be a station part called a Z-1 truss, which is a framework for holding a
range of station equipment.
The truss was considered to be ready to head for space after being
inspected by some of the shuttle Discovery crew that is to deliver it.
"Hopefully, we'll light up the night sky for all of you," Discovery's
commander Brian Duffy said after looking closely at the part. At
19,300 pounds - the U.S. built Z-1 truss will provide a range of power
and heating capabilities for the station.
Following the recent docking of a Progress supply vehicle to the station,
controllers pressurized the vestibule between Progress and Zvezda and
conducted a successful check for leaks. The seven-member crew of
STS-106 will unload supplies and equipment from the Progress into the
station through the vestibule.
A successful test firing of thrusters on the Progress craft was also
performed and changed the velocity of the station by about 2-miles per hour
(one meter per second). A second firing again changed the velocity and
one or two more firings may be performed to fine-tune the station's position
for the rendezvous with STS-106.
With the docking of Zvezda, the next phase in the development and
installation of the ham radio gear on ISS is the launch and installation of
the Initial, Phase 1 Amateur Radio station. This is currently scheduled to
occur on STS-106.
The initial station will include 2-meter and 70cm handheld radios, TNC,
a specially developed headset, signal adapter module, and specially
developed power adapters and the interconnecting cabling. The antenna
systems that the Italian/Russian/US team have developed for the
Service Module are ready but cannot be installed until later next year.
In the meantime, the ARISS international team has received permission
to use the Zarya antennas on 2-meters.
This is an exciting time for Amateur Radio and the International Space
Station! Stay tuned to ANS for further developments.

DIGITAL COMMUNICATIONS CONFERENCE
AMSAT NEWS SERVICE BULLETIN 233.02 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 20, 2000
TO ALL RADIO AMATEURS
BID: $ANS-233.02
ANS reminds all satellite operators to mark your calendars and start
making plans to attend the year's premier event in Amateur Radio
digital communications -- the 19th Annual ARRL and TAPR Digital
Communications Conference. The event will be held September 22-24,
2000, in Orlando, Florida.
The Conference is an international forum in digital communications,
networking and related technologies. It is an excellent opportunity
for those involved to meet, publish their work and present new ideas
and techniques for discussion.
The Digital Communications Conference is not only for the digital expert,
but has been designed for digitally oriented amateurs of all levels of
experience. Entire sessions with beginning, intermediate and advanced
presentations on selected topics in digital communications will be
offered. Topics will include APRS, Satellite Communications, TCP/IP,
Digital Radio and Spread Spectrum.
Full information on the conference (along with hotel information) can be
obtained by contacting:

ANS IN BRIEF
HR AMSAT NEWS SERVICE BULLETIN 233.03 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 20, 2000
TO ALL RADIO AMATEURS
BID: $ANS-233.03
ANS news in brief this week includes the following:
** A recent Ariane-4 rocket launch from French Guiana placed two
telecommunications satellites into orbit. The Brasilsat-B4 and
Nilesat-102 satellites both entered successful orbit some 25 minutes
after launch. Brasilsat-B4, built by Hughes Space and Communications,
will provide television and telecommunication services throughout
Brazil. Nilesat-102, constructed in France by the European company
Astrium, will deliver digital television for North Africa and countries in
the Persian Gulf. -Arianespace/Florida Today
** There may have been far less water on Mars in the past than most
observers have assumed to date. Ancient 'river' channels may have
been formed by fierce winds carrying sand and dust, enhanced by
flows of even purer carbon dioxide gas released when the dry ice
permafrost warms up each year. This information is contained in a
detailed essay on Mars and the search for water. Checkout the article
at: http://www.spacedaily.com/news/mars-water-science-00i1.html.
-SpaceDaily
** One of the Progress cargo rockets going to Mir next year is planning
to carry a small Amateur Radio satellite named Kollibri. The satellite
reportedly will have a life span of 4-6 months and will be launched from
Progress after it is in a Mir orbit. The satellite will be equipment with
telemetry equipment, a digital voice recorder and solar panels. A web
page (in Russian) is available at the following URL:
http://www.iki.rssi.ru/kollibri/missija1.htm. -Miles, WF1F
** ANS principle satellite investigator, Mike, N1JEZ, reported he had the
"pleasure of working Ray, W2RS" who was operating as G0AUK from the
recent AMSAT-UK Colloquium. Mike reports Ray had a super signal on
UO-14. Ray was also active on AO-27 during the event. -Mike, N1JEZ
** The newly appointed president of Arianespace said recently that the
company's launch schedule will be on schedule for the rest of the year.
"The Ariane 5 will go off September 15th and there will be two more
launches the rest of the year," said Leo Mondale in a recent interview.
Minnesota-born Mondale is the nephew of former Vice President Walter
Mondale. He came on board to manage the French launch company's
U.S. sales, marketing and customer relations last month.

** In case you missed the recent AMSAT-UK Colloquium, G3RWL has
posted photo's from the event on the AMSAT-UK web site. Check out
the following URL: http://www.uk.amsat.org/Colloquium/colpix00.htm.

** Two landers are due to descend to the surface of Mars within a month
of each other in late 2003 or early 2004. Last week, NASA announced
that it would be sending a rover to the red planet. Beagle 2, the Mars
Express Lander, is due to take up its position on the Martian surface
about one month before NASA's rover lands. -SpaceDaily

AMRAD AO-27
Uplink 145.850 MHz FM
Downlink 436.795 MHz FM
Status: Software updates underway.
Software upgrades to AO-27 are currently underway. Satellite operators
are asked to refrain from transmitting on the AO-27 uplink. Resumption
of service will be announced on the AMSAT-BB and in ANS.
An AO-27 question-and-answer page is available on the AMSAT-NA
web site. The URL is: http://www.amsat.org/amsat/intro/ao27faq.html.
AO-27 uses a method called Timed Eclipse Power Regulation (TEPR)
to regulate the on-board batteries. In simple terms, TEPR times how
long the satellite has been in an eclipse (or in the sun) and decides
what subsystems to turn on or off. The AO-27 pages on the AMSAT-NA
web site include an explanation of TEPR AO-27 operations (at):

SedSat-1, signifying Students for the Exploration and Development of
Space (satellite number one) was successfully launched and placed in

SedSat-1 has downlinked months worth of telemetry data on the
performance of its electrical power system parameters. The Nickel
Metal Hydride batteries on the spacecraft were experimental and
experienced some abuse due to a power negative situation. This
