AMSAT Symposium This Weekend

AMSAT News Service Bulletin 303.01
  From AMSAT HQ SILVER SPRING, MD.
October 30, 2011
To All RADIO AMATEURS
BID: $ANS-303.01

This year's Symposium marks the 50th anniversary of the launch
of the first amateur radio satellite into space. The Symposium
is being held in San Jose, CA on November 4 thru November 6
which is the home of Project OSCAR, the organization that
built amateur radio's first satellite. As part of our
commemoration, the ARRL is bringing an OSCAR 1 prototype which
has been refurbished to help highlight this significant
milestone. Our banquet speaker, Lance Ginner, K6GSJ was a
member of the team that built OSCAR 1;  he subsequently was
involved with a number of follow-on amateur radio satellite
projects. Lance's presentation promises to be a fascinating
look at the early days of amateur radio in space as well as
perhaps some lessons learned.

The Symposium is an excellent opportunity to learn about the
success of ARISSat-1 as well as AMSAT's latest project, Fox
and the steps that we're taking to continue to keep amateur
radio in space.  There are some excellent presentations
scheduled that will cover the gamut from satellite engineering
to satellite operations to education outreach.
This year's "Proceedings of the AMSAT-NA Space Symposium and
Annual Meeting", which is provided to every Symposium attendee
contains 21 papers and is over 250 pages in length. While not
all papers will be presented, there are also several
presentations scheduled to be presented where the material was
not finished in time for publication.

Along with the outstanding materials presented, Symposium
offers a great opportunity to meet the AMSAT leadership (the
Board of Directors members as well as Senior Officers), other
satellite enthusiasts, and interact with our volunteers who
are involved with our engineering projects. Symposium is both
a presentation/educational opportunity as well as  a social
event.

If you haven't yet registered for this year's Symposium,
please consider joining us.  Details on the Symposium and
registering can be found at:
http://www.amsat.org/amsat-new/symposium/2011/index.php
The last time that AMSAT held a Symposium in California was in
2006;  this may be the best chance for AMSAT members and
others living on the West Coast to participate in a Symposium
and have direct interaction with the AMSAT leadership for some
time.   Hopefully, those of you living in the Bay Area will
take full advantage of this opportunity. Alan Bowker, WA6DNR
and his team have done a great job preparing for an
outstanding weekend in San Jose.

See ya in San Jose!

PW-Sat to Launch in January

This week AMSAT-UK web site carried the announcement that
PW-Sat,a 1U CubeSat to be launched on the first VEGA flight in
January,will carry a 145 to 435 MHz Amateur Radio transponder.

The single channel transponder will operate in a similar way
to AO-16.

The uplink on 145.900 MHz will be FM and the downlink on
435.020MHz will use the BPSK telemetry beacon transmitter to
produce Double Sideband (DSB) that can be received on an SSB
radio.

PW-Sat will be launched into a 300 by 1450km 69.5 degree orbit
and may be expected to have a lifetime of about 2 years before
re-entry. It was built by students of Warsaw University of
Technology in cooperation with the Space Research Centre and
will be Poland's first satellite.

The development and construction of this satellite, students
worked with two research groups - Astronautical Students
(Faculty MEiL)and Space Engineering Student (Faculty EITI).
Tutor from the
beginning of the project was prof. Assoc. inz. Piotr Wolanski
MEiL department.

The main objective of the project is education of students in
the preparation, construction and use of artificial
satellites. Specific objectives are:

+ Testing the system to develop flexible solar generation.

+ Study the deacceleration of a satellite, which will increase
the resistance and its rapid descent from orbit.

+ Testing of satellite communication system including the
Technical University of Warsaw, Gdynia Maritime Academy and
the Centre for Astronomy them. Nicolaus Copernicus Academy of
Sciences.

PW-Sat has five modes of operation:

1. Receive only mode - no downlink
2. Beacon CW mode - Downlink On-Off Keying (OOK) CW (1kHz) 12
WPM on 435.020 MHz
3. Beacon BPSK mode - Downlink BPSK (3 kHz) 1200 bps AX25 (1
frame on 20 sec) on 435.020 MHz
4. Control communication mode. Downlink BPSK (3 kHz) 1200 bps
AX25 on 435.020 MHz
5. Voice Repeater mode (aka 'AO16' mode) - Uplink145.900MHz
FM(15 kHz) Downlink 435.020MHz DSB (3 kHz)

NASA ELaNa III Cubesat Launch Orbits Cubesats

NASA launched five small research satellites, or CubeSats, for
four
universities on October 28 from Vandenberg AFB. This will be
the 3rd
installment of the Educational Launch of Nanosatellite (ELaNa)
miss-
ions. The CubeSats are manifested as auxiliary payloads on the
Delta II launch vehicle for NASA's NPOESS Preparatory Project
(NPP)
mission.

The ELaNa III Cubesat Launch included RAX-2, MCubed, E1P,and
AubieSat
are all trackable by most OSCAR stations. As of press time

SatPC32 Version 12.8b Available

AMSAT News Service Bulletin 303.08
  From AMSAT HQ SILVER SPRING, MD.
October 30, 2011
To All RADIO AMATEURS
BID: $ANS-303.08

SatPC32 version 12.8b is available for download at
http://www.dk1tb.de/downloadeng.htm

The main SatPC32 program window now displays more information
such as the date of the Keplerian elements file in use.

Before upgrading your SatPC32 installation, be sure to use the
new program (in the ZIP file) to backup your user
configuration.  The upgrade erases all previous user
configurations, but the new program will restore your
configurations after upgrading.

The download is a demo version that requires users to enter
their lat/lon each time the program is started.  To make the
program fully functional, enter your existing registration
code or purchase a registration code from the AMSAT web site:
http://www.amsat-na.com/store/category.php?c=Software

DK1TB, the author of SatPC32 has donated the software to
AMSAT.  All sales of SatPC32 are used to support AMSAT.

Here are the changes described in the What's New file:

1. SatPC32, SatPC32ISS, Wisat32 and SuM now support rotor
control of the
M2 RC-2800 rotor system.

2. The CAT control functions of SatPC32, SatPC32ISS and
Wisat32 have been expanded. The programs now provide CAT
control of the new Icom transceiver IC-9100.

3. The main windows of SatPC32 and SatPC32ISS have been
slightly changed to make them clearer. With window size W3 the
world map can be stretched (only SatPC32).

4. The accuracy of the rotor positions can now be adjusted for
the particular rotor controller. SatPC32 therefore can output
the rotor positions with 0, 1 or 2 decimals. Corrections of
the antenna positions can automatically be saved. In previous
versions that had to be done manually.

5. The tool 'DataBackup' has been added. The tool allows users
to save the SatPC32 program data via mouse click and to
restore them if necessary. After the program has been
configured for the user's equipment the settings should be
saved with 'DataBackup'. If problems occur later, the program
can easily restore the working configuration.

6. The rotor interfaces IF-100, FODTrack, RifPC and KCT
require the kerneldriver IOPort.SYS to be installed. Since it
is a 32-bit driver it will not work on 64-bit Windows systems.
On such systems the driver can cause error messages.To prevent
such messages the driver can now optionally be deactivated.

7. SuM now outputs a DDE string with azimuth and elevation,
that can be evaluated by client programs. Some demo files show
how to program and configure the client.
