Folks,

Ein Auszug aus den aktuellen Nachrichten der AMSAT.  Das Teil könnte für
unsere geplante, mobile Groundstation interessant sein.

WRAPS: A Portable Satellite Antenna Rotator System


The January 2014 edition of QST contains an article by ARRL
Education and Technology Program Coordinator Mark Spencer WA8SME on a
portable azimuth and elevation rotator system for tracking satellites
called WRAPS.

WRAPS stands for Wobbler RadFxSat Antenna Pointing System rotator
system which Mark developed to support tracking CubeSats such as
FUNcube-1 and the upcoming Fox-1 and RadFxSat/Fox-1B. His target
audience includes school groups who want to access the capabilities
of the CubeSats.

Thanks to Mark and the ARRL a copy of the article in PDF format is
available here WRAPS - Mark Spencer WA8SME QST Jan 2014 Copyright

without written permission from the ARRL.

Mark Spencer WA8SME gave a presentation on WRAPS during the 2013
AMSAT Space Symposium in Houston, Texas, on Friday, November 1, 2013.
His talk was recorded by Patrick Stoddard VA7EWK.

Apologies for missing the start of Mark's introduction, and for the
quality of this video. The Symposium organizers dimmed the lights in
the front of the room for this presentation, which meant Mark was
essentially standing in the dark as he gave his presentation.

At the AMSAT Forum at the 2013 Dayton Hamvention the presentations on
education wrapped up with a talk by Mark Spencer, ARRL Education &
Technology Program Director. "Spence", WA8SME, briefly described his
classroom experiments for measuring the "wobble" of the Fox
satellite, demonstrating a Maximum Power Point Tracker (MPPT) for a
solar array, and WRAPS a lower cost azimuth-elevation rotor system
for lightweight satellite antennas.

A limited number of complete WRAPS systems will be available through
the AMSAT-NA Store. As of December 12 they were not yet available,
and AMSAT-NA do not at present have a firm date when they will be in
stock. Because of uncertainty of the price and number which will be
available, they are not taking advanced orders. When they are ready
to process orders, AMSAT-NA will make the information public.
Please do not call the AMSAT office.

announcement]
