UNAMSAT-1 Team Leaves For Moscow

David Liberman (XE1TU) reports that he and the the UNAMSAT-1 team have
left for Moscow on Monday, 13-MAR-95.  The planned launch date for the
UNAMSAT-1 MICROSAT is presently scheduled for 28-MAR-95 with the launch
window opening beginning at 05:00 UTC and closing at 10:00 UTC.  For all
those who wish to monitor, the following frequencies have been given by
XE1TU for the UNAMSAT-1 MICROSAT:

DOWNLINK:      TX1   * default *    437.135 MHz
               TX2                  437.179 MHz

UPLINK:        Channel A   145.922 MHz
               Channel B   145.942 MHz  (Channel D does not exist)
               Channel C   145.962 MHz
               Channel E/F 145.872 MHz

All are invited to monitor and collect telemetry of UNAMSAT-1 after sep-
aration from the launch vehicle.  UNAMSAT-1 is programmed to start sending
sending telemetry 20 minutes after launch.  The Bulletin Board System
(BBS) will be closed and all users are asked not to try to uplink to
UNAMSAT-1 after launch.  Only command stations will be allowed to use
uplink to UNAMSAT-1 for the first couple of days from launch.  XE1TU
recommends that all use the preliminary element set provided by 4X1AS
for UNAMSAT-1.

The following information about the TECHSAT/UNAMSAT launch was provided by
4X1AS:

     TECHSAT1 will be launched on the 28th of March from Plesetsk Russia,
     about 700 km north of Moscow.  The launcher is called START.  The
     altitude will be approximately 670 KM and the orbit will be circular,   
     however, not sun synchronous.

     Keplerian elements will be updated close to launch date.

          Satellites: TECHSAT-1 and UNAMSAT-1
               Epoch time:      95087.37500000      (Separation)
               Inclination:      075.3991 deg
               RA of node:       328.7324 deg
               Eccentricity:    0.0015304
               Arg of perigee:   101.9385 deg
               Mean anomaly:     355.9607 deg
               Mean motion:   14.7000703 rev/day

NOTE: The UNAMSAT-1 frequencies given in last week's ANS bulletins, ANS-070.01,
      were in error.  Those frequencies came given to WD0HHU in September
      of '93 and were preliminary.  However, all the other information was
      correct.

[The AMSAT News Service (ANS) would like to thank David Liberman (XE1TU)
 and 4X1AS for the information which went into this bulletin.]

BID: $ANS-077.02

Weekly OSCAR Status Reports: 18-MAR-95

AO-13: Current Transponder Operating Schedule:
The Mode Schedule from 20-FEB-95 until 22-MAY-95 will be:
Mode-B  : MA   0 to MA 190 |Omnis : MA 250 to MA 140
Mode-BS : MA 190 to MA 218 |
Mode-S  : MA 218 to MA 220 |<- S beacon only
Mode-S  : MA 220 to MA 230 |<- S transponder; B trsp. is OFF
Mode-B  : MA 230 to MA 256 | Blon/Blat 230/0
Note: The Mode-B beacon is ON during the Mode-S transponder operations only.
Please do NOT uplink to the B transponder during Mode S only, as it inter-
feres with Mode-S operations.  [G3RUH/DB2OS/VK5AGR]

AO-10: DL1SDX reports that he has heard AO-10 come back alive after a long period
of silence on 20-FEB-95 and 23-FEB-95.  At that time he only got a
a weak FMing signal when he tried to use the Mode-B transponder.  However,
VK2EYI used AO-10 and made a contact with KN6M and JE4XGW and, he noted,
that signals were excellent! [DL1SDX & VK2EYI]

AO-13: VK2EYI reports that AO-13 has been sending down excellent signals
this past week in VK land.  [VK2EYI]

RS-15: VK2EYI reports that RS-15 has been sounding strong and he has heard
station 4S7AVR using RS-15 several times.  Also, G3IOR reports that he has heard
alot of activity from RS-15 from stations in Eastern and Western Europe.  [VK2EYI
& G3IOR]

FO-20: ON4ALY reports that he has used FO-20 this past week but the signals
were quite weak.  [ON4ALY]

The AMSAT NEWS Service (ANS) NEEDS YOUR HELP! The ANS looking for volun-
teers to contribute weekly OSCAR status reports.  If you have a favorite
OSCAR which you work on a regular basis and would like to contribute to
this weekly bulletin, please send your observations to WD0HHU at his
CompuServe address of 70524,2272, on INTERNET at wd0hhu@amsat.org, or to
his local packet BBS in the Denver, CO area, WD0HHU @ N0QCU.  Also, if
you find that the current set of orbital elements are not generating the
correct AOS/LOS times at your QTH, PLEASE INCLUDE THAT INFORMATION AS WELL.
The information you provide will be of value to all OSCAR enthusiasts.
