		        MONDAY JANUARY 4, 1998

SpaceNews originates at KD2BD in Wall Township, New Jersey, USA.  It
is published every week and is made available for non-commercial use.

Dennis Wingo reports that SEDSAT is continuing to perform as it has since
launch, meaning that it is transmitting telemetry until the batteries die
and then goes into safe mode for ten hours and repeats the process.  The
orbital geometry is such that controllers have had as much as 120 hours
of continuous operation from the bird before the batteries die.

Controllers still have several chances to recover the satellite and bring
it into an operational state.  It turns out that one of the two receivers
on the satellite was disabled before launch.  (Don't ask why).  The second
receiver may or may not have been working before launch.  This fact is in
some dispute which in and of itself is not good.  However, controllers have
a method of testing the receiver/receivers on the satellite.  In the next
week or so, controller are expected to send up a reset command to the bird.
This is a hard reset that does not require the intervention of the on board
computer to function.  Doing this, controllers hope to determine if either
of the receivers on the satellite are working.  If they are, then there
are some things controllers can do to overcome a software bug that has
recently been discovered.

* RS-13 NEWS *
Several reports have been received indicating that the RS-13 satellite
has recently been switched into Mode A operation to the delight of many
Mode A satellite users.

Since NORAD still has not re-acquired AO-10, and the old keps from 1998
day 207 are now quite out of date, Stacey Mills has generated a new set
of Keplerian orbital data for OSCAR-10:

Miguel Menendez, EA1BCU, reports that a complete collection of OSCAR-16
whole orbit telemetry data for 1998 may be accessed via the Internet at
the following URL:


* KO-23 NEWS *
Several reports have been received indicating that the KITSAT-OSCAR-23
satellite has gone silent.  No official word from spacecraft controllers
has yet been received.

Ray Soifer, W2RS, thanks all who participated in OSCAR SKN 99.
Some nominations for "Best Fist" have already been received by Ray.
If you haven't yet sent yours in, please take a moment to nominate
someone you worked.

To submit a "Best Fist" nomination, please address it via packet
radio to W2RS @ WA2SNA.NJ.USA.NA or W2RS @ GB7HSN.#32.GBR.EU
(whichever is closest to you), via the Internet to <w2rs@amsat.org>,
or via "snail-mail" to W2RS' callbook address.  Those nominated will
be featured in a bulletin sent to Amateur Radio publications and
posted to ANS, packet radio and the Internet in early February.
