AMSAT News Service Bulletin 349.06 From AMSAT HQ
SILVER SPRING, MD. DECEMBER 15, 2002
To All RADIO AMATEURS
BID: $ANS-349.06
RUDAK will be on for 72 minutes (16 MA units) from MA 136 to 152 on selected
orbits over RUDAK command stations. The tasks to be accomplished are
discussed
in Jim White's post as below. Note that the middle beacon and passbands will
be
off during RUDAK sessions.

----------------------------------------------------------------------------
----
We will be resuming RUDAK work on AO-40 soon with a short (about 1 hour)
window
during orbits when the satellite is in view of the command stations in
Colorado
and Alabama. RUDAK will be on only on those orbits.
The objectives of this series of RUDAK windows are to do some further
testing in
preparation for implementing DSP based digital links to RUDAK that ground
stations
with modest equipment can use as well as to gather data from the radiation
experiment (CEDEX). Additionally, if time allows, further work to collect
good
pictures from SCOPE may be undertaken. The objective of the SCOPE work is to
compress pictures on-board to reduce the file sizes and it possible to
routinely
take pictures, and implement a scheduler so the earth can be imaged when the
satellite is not in view of a command station. New command software will
also
be tested.
The window is being constrained to about 70 minutes and only when in view of
the command stations in order to limit the impact on transponder operations.
Stacey has announced the implementation of the RUDAK windows in the
scheduler.
Please see the FAQ at http://www.amsat.org/amsat/sats/ao40/ao40-faq.html for
further information about AO-40 and RUDAK.
