* WEBERSAT NEWS *
=================
WEBERSAT (WO-18) is broadcasting new pictures and light spectrometer data
weekly. Software for the extraction, decoding, and display of spectrometer
data, written by Bob (KB7KCL), is available on LO-19 (file #s 371a/3739),
or directly from Weber State University. Monday UTC continues to be the
day for the broadcast of the most recent spectrum, along with the week's
WOD.
WeberWare 1.0, 1.2, 1.3, or a similar program is required for picture
extraction, decoding, and display. WeberWare 1.3 is the current software
version, and is available from Weber State University, AMSAT-NA, or AMSAT-UK.
The most recent WeberSat double field image is number 10/14, which was taken
of an as yet unidentified area of Northern Nigeria, Africa. The photo has
very few clouds, and land features are clearly visible. Expect new photos
sometime during the week of May 9th.
WO-18 is currently sending spacecraft solar array current whole orbit data
(WOD). This is an excellent opportunity for a student, group, or class to
use this data for spacecraft motion studies, or for studying the long term
effects of the space environment on solar cell effeciency. WOD collection
and broadcast will adhere to the following schedule:

* MICROSAT DESIGN AT STANFORD *
===============================
Over the years a number of Stanford researchers have been involved in the
design and operation of dozens of different kinds of space vehicles. But,
beginning this year, the Aeronautics and Astronautics Department has
initiated a new program that involves students in designing, constructing
and controlling small, simple and inexpensive "microsatellites" that are
launched into orbit.
On Thursday, April 21, two dozen engineering students involved in this
program at Stanford University showed a mock-up of their first satellite
design to a visiting Russian official, Yuri Plotnikov, professor of flight
mechanics and control design at the Moscow Aviation Institute.
If the project goes as planned, a year from now the 2-foot-wide hexagonal
satellite will hitch a ride on top of a Delta rocket along with a commercial
satellite. Once it goes into orbit, the satellite will begin beaming back
digital pictures of Earth and broadcasting its position and status over ham
radio channels with a synthesized voice.
"The program has two major objectives," said Robert Twiggs, a visiting
professor brought to Stanford from Weber State University in Utah to
jump-start the new small satellite development laboratory. "First is to give
graduate students in aero-astro and other departments practical, hands-on
experience in designing and building something that can be launched into
space in only a year on a very limited budget. Second is to provide
faculty, students, space experimenters and industry with an opportunity
to do inexpensive space experiments."
Plotnikov's interest stems from the fact that the Moscow Aviation
Institute is a professional school with 15,000 students devoted to aerospace
design. "The name is historical. Actually, we design anything that flies,"
he said. The institute currently has a joint satellite program with Utah
State University. When asked whether something similar is likely with
Stanford, he shrugs and replies, "It's all a matter of funding."
The students have nicknamed their design the Stanford (or Satellite) Quick
Research Testbed, or SQUIRT. They hope that this could become a de facto
standard for microsatellites, which are a growing phenomenon worldwide.
Students at the University of Umea in Kirna, Sweden, are working on a
parallel design. So far, about a dozen student-designed microsatellites
have been built and launched.
The watchwords for these satellites are simple and inexpensive. So the
Stanford design uses powerful magnets to keep the satellite aligned
perpendicular to the Earth's magnetic field, rather than employing
complicated gyros and thrusters to control its position.
"Usually, the reason for a satellite is its payload. But we are doing
things backward. Our purpose is to get the experience of designing the
satellite, so what it carries is of secondary importance. However, we've
tried to come up with a payload that will be interesting and worthwhile,"
said Christopher Kitts, a graduate student in mechanical engineering.
The payload the students have agreed upon is a digital camera, voice
synthesizer and global positioning satellite system receiver. The GPS
receiver will allow student controllers to determine the satellite's
position. Simple photocells will determine when the camera is pointing
toward the Earth. That will allow the Logitech digital camera to snap
images of different parts of the globe that will be transmitted by radio
to interested ham radio operators.
According to Kitts, participants hope that the pictures and synthesized
messages from the satellite can be used in elementary schools, middle
schools and high schools to help interest students in science.

The North American Center for Emergency Communications, Inc.(NACEC)
Affiliate
Radio
System
(NARS)
NACEC is being developed to serve the emergency communications needs of
Military Families, Disaster Victims and Disaster Relief Operations. Thi
being done by building one of the most powerful commercial grade radio
communication centers in North America and making it services available
new tool to support the communications needs in these areas. NACEC
accomplishes this mission by maintaining its communications center's abi
to operate on and support radio communications on the Commercial, Milita
Federal Gov., State Gov. and Amateur Radio parts of the RF spectrum.
NARS is the Amateur Radio traffic support network for NACEC.
NARS is being developed as a high speed emergency traffic network consis
of trained and dedicated radio operators. Training & Testing are provid
during weekly radio nets that are conducted on amateur radio frequencies
NARS is intended for only those amateur radio operators that are serious
about helping others.
All MARS (Military Affiliate Radio System) members of any branch of
MARS are encouraged to participate. NARS is being fashioned after the
Army MARS network. It is hoped that NARS will help provide a better
understanding (and remove misconceptions) of the value of MARS,
while at the same time creating a system of combined Amateur and MARS
operators to handle emergency traffic. It is also hoped that NARS will
also create the opportunity for many new amateurs to join and increase
the membership of the various MARS programs. NARS membership currently
consists of about 25% MARS and 75% Non-MARS operators.
NARS Information & Training Nets are directed nets. All members of
the Amateur Radio Community are welcome to participate.
NARS nets meet on the following weekdays and times:
Week Day Net ID Time Freq. Mode
Sundays: NARS/A 24:00 UTC/7:00 PM LST 3.860 LSB
NARS/B 23:00 UTC/6:00 PM LST 7.262 LSB
NARS/C 22:00 UTC/5:00 PM LST 14.347 USB
** All HF nets meet +/- QRM and band usage.
Thursdays: In the Minneapolis & St.Paul Minnesota Area Only.
This net is currently held on the TCFMC repeater.
NARS/D 02:00 UTC/9:00 PM LST 146.76 FM
* LST is Minnesota Local Standard Time.
