AMSAT NEWS SERVICE
ANS 111
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.
ANS is pleased to announce the 20th Space Symposium and AMSAT-NA
Annual Meeting. The conference is scheduled for November 7-11, 2002 in
Fort Worth, Texas, and will chronicle recent and future Amateur Radio
satellite technology developments, including an Electronic Surplus Stores
tour on November 7th; a Field Operations breakfast and a tour of the
Lockheed Martin Aerospace Company on November 10th; and the
AMSAT-NA Board of Directors Meeting November 10th (AMSAT members
are welcome to attend the BOD meeting. [The 2002 event chairman is
Keith Pugh, W5IU]
This ANS bulletin set is dedicated to the memory of Earl Smith, W5EZ,
a longtime Johnson Space Center Amateur Radio Club member who
died recently of an apparent heart attack. W5EZ currently served as the
club librarian and will be missed by his many JSC club members. [ANS

ADVANCED DATA COMMUNICATIONS
AMSAT NEWS SERVICE BULLETIN 111.01 FROM AMSAT HQ
SILVER SPRING, MD, APRIL 21, 2002
TO ALL RADIO AMATEURS
AMSAT-NA's Rick Hambly, W2GPS, recently reminded satellite
operators that AMSAT-NA is in the process of developing two new
satellites; OSCAR-Echo is being designed to be a LEO EasySat with
voice and data capabilities; and Eagle, which is going to be an elliptical
bird with linear transponders.
In addition to the standard compliment of transponders, there is room on
both satellites for optional payloads.
One such payload under consideration is a transponder to support the
development of ADCARS - Advanced Data Communications for the
Amateur Radio Service. This project involves the use of a very high
speed wideband data communications channel to simultaneously carry
multiple voice, data, and video. The characteristics of the channel would
be such that link margins and quality of service will be significantly
improved over conventional techniques.
The major effort to achieve these goals will be associated with the
development of ground station hardware and software. New transmitter,
receiver and antenna designs will also be needed. Other technology
issues will include modulation, coding, interleaving, and channel access
methods.
There are four areas of design and development that are needed to put
such a payload on the new satellites. They include transmitter design,
receiver design, CPU design, and payload integration.
Can you help?
W2GPS is now appealing to the AMSAT membership at large. Here
is your chance to design something that will actually fly in space!
Contact Rick, W2GPS, at < w2gps@cnssys.com > for more information.

ATLANTIS ISS MISSION UPDATE
AMSAT NEWS SERVICE BULLETIN 111.03 FROM AMSAT HQ
SILVER SPRING, MD, APRIL 21, 2002
TO ALL RADIO AMATEURS
BID: $ANS-111.03
The mission of outfitting the newest components of the International
Space Station continued this past week and included the mission's third
and forth spacewalks. Shuttle astronauts Steve Smith and Rex Walheim
continued installation work on the S-Zero Truss, now permanently
attached to the station's U.S. laboratory - Destiny. During the 6?-hour
spacewalk, Smith worked from a platform on the station arm, operated
by Mission Specialist Ellen Ochoa and Flight Engineer Dan Bursch. In
addition, Shuttle astronauts Jerry Ross and Lee Morin accomplished the
fourth and final spacewalk of the STS-110 mission, with many of their
tasks focusing on helping future spacewalkers.
Ross, N5SCW, set a personal best, making his 9th spacewalk during
his seven orbital flights. The retired Air Force Colonel set a record for
the greatest number of flights and spacewalks by an astronaut or
cosmonaut!
Prior to his current flight, N5SCW had logged 1,133 hours in space.
The first space railroad car received its first trial run last Monday,
highballing along 26 feet of the track atop the ISS S-Zero (S0) Truss at a
maximum speed of one inch per second, or 100 yards an hour.
The 10 crewmembers also participated in a news conference with media
representatives at NASA centers in Florida and Houston and at Mission
Control Moscow. The event was also carried live on NASA television.
In addition to the news conference, astronaut Dan Bursch talked to an
excited group of students at the Quogue School in Quogue, New York.
A crowd of 123 fellow students and about 100 parents witnessed the
Earth-to-space interview in the school auditorium. This was followed by
astronaut Carl Walz being interviewed by youngsters at the Caribbean
Preparatory School in Puerto Rico. Both contacts with NA1SS were
arranged through the Amateur Radio on the International Space Station
(ARISS) program.
On Thursday Atlantis left the International Space Station after a
successful mission to bring the centerpiece of the station's main truss to
the orbiting laboratory and four successful spacewalks to connect and
outfit it.
In a related event, the first screening of the Space Station 3D IMAX film
took place here on Earth, and is reported to be "breathtaking" by ARISS
members. In the movie ham astronaut Bill Shepherd talks to students in
the Texas using ARISS equipment. According to ARISS Program
Manager Frank Bauer, KA3HDO, "it is the closest way that an individual
could experience space without going to it themselves. It was
spectacular from the perspective that you really felt like you were there."

AO-27 control operator Michael Wyrick, N3UC (former N4USI), reports
AO-27 has been turn off to condition the batteries. Earlier this month, the
control operators noticed that AO-27's batteries had become very low
and was causing the transmitter to turn off early during the passes. The
on-board software was turning the transmitters off to keep the batteries
from becoming too low to keep the CPU running.
Currently, AO-27's Amateur Radio 'bent-pipe' transmitter is off in hopes
of getting enough charge to the batteries. At that time, the transmitter
will resume normal FM repeater operation. At times the control stations
will turn the transmitter on to collect 1200-baud AFSK telemetry.
An AO-27 question-and-answer page is available on the AMSAT-NA web
site, with updates by Ray, W2RS. 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):

Broadcast Callsign SASAT2-11
BBS SASAT2-12
Launched: September 26, 2000 aboard a converted Soviet ballistic
missile from the Baikonur Cosmodrome. Status: Unknown, ANS has
received no additional information.
When/if operational, SaudiSat-1B will operate as 9600-baud digital
store-and-forward systems as well analog FM repeater mode capability.
One of two new ham satellites from the Kingdom of Saudi Arabia built by
the Space Research Institute at the King Abdulaziz City for Science and
Technology.
SUNSAT SO-35
Launched: February 23, 1999 by a Delta II rocket from Vandenberg Air
Force Base in California. Status: Non-operational
The SunSat team released the following statement, dated
February 1, 2001:
We regret to announce that the last communication with SunSat from our
ground station at the Electronic Systems Laboratory at Stellenbosch
University took place recently. We are certain, after having performed
several tests since the last contact, that an irreversible, physical failure
has occurred on the satellite. It is therefore unlikely that we will have
any further contact with SunSat, apart from the occasional visual sighting
by telescope!
When it was operational the SunSat package included 1200 and 9600
baud digital store-and-forward capability and a voice 'parrot' repeater
system in addition to Mode B/J operation with two VHF and two UHF
transmit-receive systems.

TECHSAT-1B GO-32
Downlink 435.225 MHz using HDLC telemetry
Launched: July 10, 1998 by a Russian Zenit rocket from the Baikonur
Cosmodrome. Status: Semi-operational.
Last reported, the satellite does transmit a 9600-baud burst every 30
seconds (the GO-32 beacon sends one short telemetry status
transmission of 44 bytes) and upon request the complete telemetry
buffer.
[ANS has no further information]
PANSAT PO-34
Uplink/downlink frequency (listed on the PanSat web site) 436.500 MHz
Launched: October 30, 1998 by the Shuttle Discovery. Status: Unknown
The satellite is not available for general uplink transmissions.
The Naval Postgraduate School developed PanSat. At the time of
launch, PanSat spread-spectrum digital transponders were to
be available to Amateur Radio operators along with software to utilize
this technology.
The satellite is still operating, however, the spread spectrum packet radio
portion never took place. The spacecraft is now beyond it's initial 2-year
mission life, but telemetry records are still being downloaded.
For more information, visit the official PanSat web site at:
http://www.sp.nps.navy.mil/pansat/
PanSat was the featured cover article on the July/August 1999 issue of
the AMSAT-NA Journal (the story written by KD6DRA and N7HPR).

2401.220 MHz
Launched: January 22, 1990 by an Ariane launcher from Kourou,
French Guiana. Status: Non-operational.
DOVE stopped transmitting in March 1998. The 145.825 MHz and
2401.220 MHz downlinks are off the air and the satellite has not
responded to ground station control.

SEDSAT-1 SO-33
Downlink 437.910 MHz FM (9600-baud FSK)
Launched: October 24, 1998 by a Delta 2 rocket from Cape Canaveral,
Florida. Status: Semi-operational.
The satellite is not currently available for uplink transmissions and the
image and transponder recovery efforts have been unsuccessful.
SedSat-1 signifies Students for the Exploration and Development of
Space (satellite number one).
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
information has provided NASA with useful information. With the
exception of the imaging system and the use of the transponders,
SedSat-1 has been judged a success.
