========= SpaceNews ========= 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.

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. * FEEDBACK/INPUT WELCOMED * =========================== Mail to SpaceNews should be directed to the editor (John, KD2BD) via any of the following paths: FAX : 1-908-747-7107 UUCP : ...catfish.ocpt.ccur.com!ka2qhd!kd2bd PACKET : KD2BD @ NN2Z.NJ.USA.NA INTERNET : kd2bd@ka2qhd.ocpt.ccur.com -or- kd2bd@amsat.org MAIL : John A.
