B. Text of Launch Announcements.

2000-058A Cosmos 2373,
also known as Kometa 20, is a Russian cartographic
satellite that was launched from Baikonur by a Soyuz-U rocket at
09:30 UT. Its orbit will have a short life of 60 days during which
film will be periodically returned to Earth via capsule.
The initial orbital parameters
were period 89 min, apogee 265 km, perigee 185 km, and inclination
70.37 deg.
2000-057A, 2000-057B
  2000-057C, 2000-057D
A Russian rocket named Dnepr launched five
microsatellites. The rocket is a modified RS-20 ICBM, known in
the NATO countries as SS-18 and as Satan, and was launched from
a silo in Baikonur at 10:05 UT. The five satellites are not yet
matched with the International IDs, but we report them in random
order as follows. Tiungsat 1 is a Malaysian remote sensing 50 kg
satellite. The 56 kg Megsat is an Italian environment monitoring
satellite. The 10 kg Unisat is also an Italian satellite and would
aid educational advancement. The 10 kg Saudisat 1A and Saudisat 1B
are Saudi Arabian educational satellites. The initial orbits of all
five were similar: period 97 min, apogee 737 km, perigee 522 km,
and inclination 65 deg. The next bulletin will carry the
matched names and IDs of all five.
2000-056A Cosmos 2372,
also named as Yenisey and as Orlets 2, is a Russian
military photo reconnaissance spacecraft that was launched by a
Zenit 2 rocket from Baykonur at 10:20 UT. The 12 tonne spacecraft is
fitted with 22 capsules to carry and land the high resolution
photographs. Unlike previous photo reconnaissance spacecraft
which had functioned only for two to three months, this one is
expected to function for a year. The initial orbital parameters were
period 90.1 min, apogee 364 km, perigee 220 km, and inclination
64.8 deg.
2000-055A NOAA 16
is an American weather monitoring satellite that was
launched by a Titan 2 rocket from Vandenberg AFB at 10:22 UT. The
2,200 kg cylindrical (diameter 2 m, length 4 m) spacecraft carries
several atmospheric and weather monitoring instruments. The AVHRR-3
(Advanced High Resolution Radiometer) has six wavelength channels
(0.58-0.68, 0.625-1.00, 1.58-1.64, 3.55-3.93, 10.30-11.30,
11.50-12.50 microns) of which the first three monitor the backscattered
solar energy, and the second three monitor the emissions from land,
sea, and clouds, all with a spatial resolution of 1.1 km. The HIRS-3
(High-resolution Infrared Sounder) monitors the atmosphere at 19
closely spaced channels so as to derive the vertical temperature
profile out to an altitude of 40 km. The AMSU-A and AMSU-B
(Advanced Microwave Sounding Unit) capture the microwave emissions.
AMSU-A operates in 15 channels covering 23.8-89.0 GHz, and AMSU-B
in five channels covering the 89-183 GHz band to derive the
tropospheric water vapor profile. The SBUV-2 (Solar Backscatter
Ultra Violet) instrument derives the ozone profile by monitoring the
incident and backscattered radiation in 12 wavelength bands
covering the 252-340 nm band. In addition to the atmospheric
instruments, the spacecraft also carries a SEM-2 instrument to
monitor kilovolt and megavolt electrons and protons. The data are
stored on-board and transmitted over Fairbanks, AK and Wallops Island,
VA. Initial orbital parameters were period 102.1 min, apogee 850
km, perigee 843 km, and inclination 98.8 deg.
2000-054B GE 7
is an American geosynchronous communications spacecraft that
was launched by an Ariane 5 rocket from Kourou at 22:54 UT. The two
tonne spacecraft will provide direct-to-home television, voice and
data transmission through its many C-band transponders after
parking over 137 deg-W.
2000-054A Astra 2B
is a European (Luxembourg-registered) geosynchronous
communications spacecraft that was launched by an Ariane 5 rocket
from Kourou at 22:54 UT. It will provide digital video broadcasts to
most of Europe through its 30 high power Ku-band transponders
after parking over 28.2 deg E longitude.
2000-053A STS 106
is an American shuttle spacecraft that was launched from
Cape Canaveral at 13:00 UT. It carried 2.5 tonnes of cargo to dock
with and deliver to the Zvezda module of the ISS. The seven-person
crew of cosmonauts and astronauts worked also to unload the cargo
from an earlier-launched Progress craft into the Zvezda module,
and to repair, furbish, or refurbish the machines and batteries on-board
Zvezda and Zarya modules. The shuttle landed back in Cape
Canaveral at 07:56 UT on 20 September, after a 12 day mission.
Initial orbital parameters were period 92.2 min, apogee 386 km,
perigee 375 km, and inclination 51.6 deg.
2000-052A Eutelsat W1
is a European geosynchronous communications spacecraft
of that consortium that was launched by an Ariane 4 rocket from
Kourou at 22:33 UT. The Eutelsat-W constellation now has four
members including the W2, W3, and W4 that had been launched earlier.
The 1,300 kg (dry) satellite will provide voice and video
transmission to Europe and southern Africa through its 28 Ku-band
transponders after parking over 10 deg-E longitude.
2000-051A Sirius 2,
also known as SD-RADIO 2 is an American geosynchronous
communications spacecraft that was launched by a Proton-K rocket
from Baikonur at 09:44 UT. It will enable S-band digital radio
broadcasts (music, news, and entertainment) directly or through urban
relay stations to motorists in North America. The Sirius
constellation will be completed with the launch of a third
spacecraft later this year.
2000-050A Zhangguo Ziyuan 2,
also known as PRC 44 and as ZY 2, and meaning
China Resource 2, is a Chinese remote sensing spacecraft that was
launched by a Long March 4B rocket from Taiyuan launch center at
03:25 UT. It will monitor crop yields and natural disasters, and
enable urban planning. Initial orbital parameters were 94.4 min,
apogee 499 km, perigee 483 km, and inclination 97.4 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.)

    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:  [directory /igscb]

    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
    It provides many links to GPS related databases.

    The latest addition to the GPS fleet is Navstar 48 (USA 151).

  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

    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:
    maintained by the Coordinational
    Scientific Information Center (CSIC),Russian Space Forces.

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