B. Text of Launch Announcements.
1997-030A, 1997-030B, 1997-030C, 1997-030D, 1997-030E, 1997-030F, 1997-030G
IRIDIUM 14, IRIDIUM 12, IRIDIUM 10, IRIDIUM 9, IRIDIUM 13,
IRIDIUM 16, and IRIDIUM 11 are American low altitude
communications spacecraft. They were designed for linking mobile
telephone communications around the world. These seven, 650 kg
spacecraft were launched by a Proton-K rocket with a DM-2M
booster stage from Baykonur cosmodrome at 14:03 UT. Initial
orbital parameters of all were similar: period 95 min, apogee
516 km, perigee 498 km, and inclination 86.4 deg.
Fengyun 2 is a PRC geosynchronous meteorological spacecraft
that was launched by a Long March 3 rocket from Xichang launch
station at 12:01 UT. The 1,380 kg spacecraft carries a scanning
radiometer and a cloud cover mapper and was parked at 105-E
longitude to cover 100 million square-km centered on China.
Cosmos 2344 is a Russian military reconnaissance spacecraft that
was launched by a Proton-K rocket from Baykonur cosmodrome at
16:57 UT. According to a Moscow daily Kommersant this may be the
same satellite that was code named 11F66 in 1984, but whose
completion had been repeatedly delayed. The booster stage, DM-2M
used in the launch is expected to be used in several more imminent
commercial launches. Initial orbital parameters were period 130.1
min, apogee 2,748 km, perigee 1,509 km, and inclination 63.4 deg.
INSAT 2D is an Indian geosynchronous communications spacecraft
that was launched by an Ariane 44L rocket from Kourou in French
Guiana at 23:21 UT. The 2,079 kg spacecraft carries a total of 23
transponders in the C- and Ku-Bands to provide voice and video
communications to the countries in the west, south, and
southeast Asia. The parking longitude is likely to be 74-E
or 93-E longitude.
INMARSAT 3-F4 is a geosynchronous communications spacecraft
of that international consortium that was launched by an Ariane 44L
rocket from French Guiana at 23:21 UT. The 2,400 kg spacecraft
carries transponders to enable communications among mobile
vehicles, ships, and planes in the Atlantic region after parking
at 45-E longitude.
TELSTAR 5 is an American geosynchronous spacecraft that was
launched by a Proton-K rocket from Baykonur cosmodrome at 17:00 UT.
The 3,600 kg spacecraft carries 24 C-band and 28 Ku-band
transponders to provide voice and video communications after
parking at 97-W longitude.
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.
The last full list appeared as a part of SPX 520.
The list will reappear only after major updates to the list are available.
- 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]
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.
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-515. It
will not be repeated in view of the excellent updated source at:
maintained by the Coordinational
Scientific Information Center (CSIC),Russian Space Forces.
- Actual decays/landings of payload spacecraft and rocket bodies (R/B)
only. Additional information is not available.

The Mir space station suffered damage when Progress M-34 cargocraft collided with
it on 25 June 1997 while attempting an automatic docking maneuver; repair and
salvage operations are underway.
NSSDC/WDC-A-R&S is an archival center for science data from many spacecraft.
Some data are on line for electronic access. Please contact the NSSDC Request Coordination

Information on the current
status of the instruments on board from the investigators will be most
welcomed. Precomputed trajectory files
and orbital parameters of many magnetospheric and heliospheric science-payload
spacecraft may be FTP'ed from NSSDC's ANON_DIR:[000000.ACTIVE] and its
several subdirectories. (See About the SPACEWARN Bulletin
for access method; a file in the ACTIVE directory named AAREADME.DOC, outlines the contents.)

of many geocentric science payload spacecraft. The codes related to
the heliospheric spacecraft trjectories can be executed through:
