MONDAY MARCH 15, 1993
SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It
is published every week and is made available for unlimited distribution.
* STS-55 LAUNCH POSTPONMENT *
=============================
The following is a message from the SAREX working group:
The launch of the STS-55 Space Shuttle Columbia mission, carrying the
SAREX payload, has been delayed until no earlier than March 19, 1993.
Since this launch date is still tentative, a new Keplerian Element set
has not been generated. The SAREX Working group would like to remind all
radio amateurs that Official SAREX Keplerian elements are provided
primarily by 2 SAREX team members: Gil Carman, WA5NOM, at the Johnson
Space Center (JSC) and Ron Parise, WA4SIR, at the Goddard Space Flight
Center (GSFC). To ensure accurate Shuttle orbit data only rely on SAREX
Keplerian Elements generated by one of these two individuals.
* OSCAR CROSS-LINKING *
=======================
On 3rd March 1993 the DoHop team consisting of G4CUO, G4ZHG, G0NKA, G6HMS
and G7MUB successfully conducted a trans-satellite qso through RS-14/O21
to Fuji/OSCAR-20. The predictions for the experiment were as follows :
LOCAL TCA RS-14 to FO-20
================= ===============================================
AOS LOS LAT LON LOC RANGE SEPARATION
FO-20 2225:39 2249:32 049.8N 011.7W JN59UT 1990kms 773kms approx.
RS-14 2231:48 2250:29 049.8N 002.4W JN19ET 1078kms
FREQS USED: U/Link X/Link D/Link
======== ========== ==========
435.016 MHz 145.983 MHz 435.817 MHz
The Uplink remained fixed while the X/Link and D/Link were subject to
doppler shift which was measured by G4CUO for further analysis.
The mode used was F3e which transponded well through FO-20. G6HMS's TX
was RXed by G4CUO at 55 well after satellite TCA but the tape recording
has yet to be related to time.
Other stations using RS-14 were also heard, and the digitally systhesized
voice message from Junior Torres de Castro PY2BJO was RXed at 57 via FO-20.
DoHop 2 using RS-14 > RS-10 planned for 28th March 1993.

* AMSAT-LU's NEW SATELLITE *
============================
AMSAT Argentina is pleased to inform that it is working on a new
Argentine Satellite as an addition to their operational LUSAT-1,
and should be launched by the end of the year.
This new satellite will include a programmable digitalker, with up to
2 minutes of digital voice recording time available, an FM transponder/
repeater operating in Mode B (with uplink on 70 cm and downlink on 2 m),
and will downlink telemetry via a 1200 bps AX.25 beacon (standard packet).
Current plans call for attaching the AMSAT-LU satellite to a Russian
Satellite as a secondary mission (equivalent to RS 10-13 satellites),
with an agreement similar to the one used by AMSAT-DL/UA, OSCAR-21/RS-14.
Further details will be published as they are made available. Please
address any comments, suggestions, request or proposals to:
AMSAT Argentina, LU7AA @ LU7AA.CAST.ARG.SOAM or @LUSAT, @PACSAT or UO-22.
