B. Text of Launch Announcements.

2000-082A Beidou 1B
is a Chinese (PRC) navigational spacecraft that was
launched by a Long March 3A rocket from Xichang launch center at
16:20 UT. The launch of this second BEIDO completes the two-
satellite navigational system which will provide positional
information for highway, railway and marine transportation. Initial
orbital parameters were period 752.6 min, apogee 41,871 km, perigee
190 km, and inclination 25 deg.
2000-081C LDREX
(Large-scale Deployable Reflector EXperiment) is a Japanese
experimental antenna dish that was launched by an Ariane 5 rocket
from Kourou at 00:26 UT. The reflector was to stay expanded to
a diameter of 6 meters for about 20 min, after sliding out of a
tubular container on the rocket. An on-board camera was to image
and downlink the deployment process. Orbital parameters are not
available.
2000-081B GE 8
is an American geosynchronous communications spacecraft that
was launched by an Ariane 5 rocket from Kourou at 00:26 UT. The 2.2
tonne (with fuel) spacecraft carries 24 C-nband transponders to
provide voice, video, and broadband data communications to the
contiguous USA, Alaska, and the Caribbeans after parking over 139
deg-W longitude.
2000-081A Astra 2D
is a European (Luxembourg-registered) geosynchronous
communications spacecraft that was launched by an Ariane 5 rocket
from Kourou at 00:26 UT. The 825 kg (dry mass) satellite carries 16
Ku-band transponders to provide direct-to-home voice, video, and
data transmissions to Britain and neighboring countries after
parking over 28.2 deg-E lonitude.
2000-080A USA 155
is an American military (NRO) spacecraft that was launched
by an Atlas 2AS rocket from Cape Canaveral at 02:47 UT. A report
has it that it may be a satellite just to collect and relay data
from NRO’s many photoreconnaissance satellites.
2000-079A EROS A1
(Earth Resources Observation Satellite) is an Israeli
photo-reconnaissance satellite that was launched by a START 1 rocket
from the new launch site at Svobodni in Siberia at 12:30 UT. (It is
the third launch from that site. The START 1 rocket is a modified
RS-12M Topol ICBM, also known in NATO as SS-25.) The 250 kg (dry
mass) triaxially stabilized spacecraft carries a black and white high
resolution (1.8 m) CCD camera, to obtain images (with terrain width
of 12.6 km) of locations chosen by Israeli military or world-wide
commercial clients, and downlink them at one of the 14 ground
stations. The initial parameters of the Sun-synchronous orbit were
period 94.6 min, apogee 505 km, perigee 490 km, and inclination 97.3
deg.
2000-078A STS 97
is an American shuttle spacecraft that was launched from
Cape Canaveral at 03:06 UT. The main mission was to install a 72 m x
11.4 m, 65 kW double-wing solar panel on the Unity modeule of the
International Space Station (ISS). Including the support beams,
radiators and batteries, the power generator has a mass of 15.75
tonne. The previously docked Progress-M1 4 cargo spacecraft had to
be temporarily evicted from the ISS before the installation. It
required several spacewalks by the crew to extend the panel taught
enough. The shuttle landed back in Cape Canaveral at 23:03 UT on 11
December. The initial orbital parameters of STS 97 were period 91.7
min, apogee 365 km, perigee 352 km, and inclination 51.6 deg.

C. Spacecraft Particularly Suited for International Participation

  1. Spacecraft with essentially continuous radio beacons on frequencies
    less than 150 MHz, or higher frequencies if especially suited for ionospheric
    or geodetic studies. (NNSS denotes U.S. Navy Navigational
    Satellite System. Updates or corrections to the list are possible only with
    information from the user community.)

    Note:
    The full list appeared in SPX 545.
    The list will not be repeated in future issues until significantly revised again.

  2. Global Positioning System satellites useful for navigational
    purposes and geodetic studies. (“NNN” denotes no national name. SPACEWARN
    would appreciate suggestions to update this list. An asterisk [*] denotes
    changes in this issue.)

    High precision (<20 cm) GPS constellation tracking data obtained from
    the network of about 80 dedicated global stations that are of interest to
    geodetic study may be obtained through the following services provided
    by the International Association of Geodesy (IGS)

         FTP:    igscb.jpl.nasa.gov  [directory /igscb]
         WWW:    http://igscb.jpl.nasa.gov/
         E-mail: [email protected]
    

    The standard format of the GPS situation appeared in SPX-518. It will not
    be repeated since an excellent source of trajectory- and science-related GPS information is at
    http://www.utexas.edu/depts/grg/gcraft/notes/gps/gps.html#DODSystem
    It provides many links to GPS related databases.

  3. Russian Global Navigational (Positioning) Spacecraft, GLONASS
    constellation. (SPACEWARN requests updates/additions from readers to this list.
    Entries marked “*” are updates or additions to the list.)

    All GLONASS spacecraft are in the general COSMOS series. The COSMOS numbers
    (nnnn) invoked by USSPACECOM have often differed from the numbers (NNNN)
    associated in Russia; when different, the USSPACECOM COSMOS numbers are shown
    in parentheses. The corresponding GLONASS numbers are Russian numbers, followed
    by the numbers in parentheses that are sometimes attributed to them outside
    Russia.

    The operating frequencies in MHz are computed from the channel number K.
    Frequencies (MHz) = 1602.0 + 0.5625K and L2 = 1246.0 + 0.4375K.

    The standard format of the GLONASS situation appeared in SPX-545. It
    will not be repeated in view of the excellent updated source at:
    http://www.rssi.ru/SFCSIC/english.html
    maintained by the Coordinational
    Scientific Information Center (CSIC),Russian Space Forces.

  4. Visually bright objects.

    A comprehensive list of visually bright
    objects with their two-line orbital elements is available from USSPACECOM, via a
    NASA URL, http://oig1.gsfc.nasa.gov/files/visible.tle. The list, however,
    does not include visual magnitudes, but are expected to be brighter than
    magnitude 5.

  5. Actual decays/landings of payload spacecraft and rocket bodies (R/B)
    only. No further information is available.

  6. Miscellaneous Items. (This section contains information/data that
    are entered on occasion and may not be repeated in each issue of the
    SPACEWARN Bulletin.)

    The USSPACECOM has rematched the names with the IDs for the following
    two spacecraft, after input from the launching agencies; the names are just
    reversed.

          2000-057A (26545) Saudisat 1A
          2000-057D (26548) Tiungsat 1
