B. Text of Launch Announcements.
(also known as Arkon) is a Russian military
reconnaissance satellite that was launched by a Proton-K rocket
from Baikonur at 15:13 UT on 25 July 2002. The 2.6 tonne (with fuel)
satellite carries a high-resolution imager with a 1.6 meter mirror
telescope to provide images at a resolution of one meter. The images
will be distributed for sale by a Russian company. The initial
orbital parameters were period 120 min, apogee 1,834 km, perigee
1,507 km, and inclination 63.5 deg.
|2002-036A, 2002-036B||Cosmos 2390 and Cosmos 2391
Cosmos 2391 and Cosmos 2390 are Russian military communications
satellites that were launched by a Cosmos-3M rocket from Plesetsk
at 06:36 UT on 8 July 2002. (These 200 kg satellites are reported
to belong to the “Strela-3 class” of satellites.). The initial
orbital parameters of both were close: period 115.7 min, apogee
1,507 km perigee 1467 km, and inclination 82.5 deg.
is a Japanese geostationary communications spacecraft
that was launched (along with STELLAT 5) by an Ariane 5 rocket
from Kourou at 23:22 UT on 5 July 2002. The 1,625 kg (with fuel),
1,400 W triaxially-stabilized satellite will provide mobile
telephony, data transfer and maritime communications to Japan and
neighboring area through its S- and C-band transponders after
parking over 135 deg-E longitude.
is a European geostationary communications spacecraft
that was launched (along with N-STAR 3) by an Ariane 5 rocket from
Kourou at 23:22 UT on 5 July 2002. It will provide television and
two-way Internet services to Europe, North Africa and Middle East
through its 35 Ku-band and 10 C-band transponders after parking over
5 deg-W longitude.
CONTOUR (Comet Nucleus Tour) is an American (NASA) heliospheric
spacecraft that was launched by a Delta 2 rocket from Cape Canaveral
at 06:47 UT on 3 July 2002. The 970 kg will remain in Earth-orbit
until about 15 August 2002, when it will begin the heliospheric
voyage of four or more years to meet at least two comets, Comet
Encke on 12 November 2003, and Comet Schwassmann-Wachmann 3 (SW3)
on 19 June 2006, at a distance of 100 km from each nucleus. Before
each encounter, it will undergo a speed boost by an Earth swingby.
It carries four instruments to image the comets and analyze the
emitted dust and gaseous material.
CRISP (Contour Remote Imager/Spectrograph) is a 12 kg, 36 W
CFI (Contour Forward Imager) is a 4 kg, 2 W instrument that will
NGIMS (Neutral Gas Ion Mass Spectrometer) is a 9 kg, 23 W instrument
CIDA (Comet Impact Dust Analyzer) is a Time-of-Flight (ToF) ion mass

C. Spacecraft Particularly Suited for International Participation
- 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.
- Global Positioning System satellites useful for navigational
purposes and geodetic studies.
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)

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.
- Russian Global Navigational (Positioning) Spacecraft, GLONASS
constellation. (SPACEWARN requests updates/additions from readers to this 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.
The latest addition to the GLONASS fleet are Cosmos 2380, Cosmos 2381, and
- Visually bright objects.
A comprehensive list of visually bright
objects with their two-line orbital elements is available from USSPACECOM, via a
NASA site, http://oig1.gsfc.nasa.gov/files/visible.tle. The list, however,
does not include visual magnitudes, but are expected to be brighter than
