B. Text of Launch Announcements.
Priroda is the last of the scheduled five Russian modules of Mir
and was launched from Baykonur by a Proton-K rocket at 11:48 UT
to dock after three days rather than the usual nine days. The launch
itself was three days earlier than the planned data in order to
facilitate an American microgravity program; the 19,000 kg module
carried 900 kg of American equipment to be delivered to the
American astronaut on Mir. Other cargo on board included several
remote-sensing Russian instruments. It is likely Priroda may later
be attached to the planned international space station, Alpha, when
Mir mission would in 1998. Initial orbital parameters were period
89.9 min, apogee 454 km, perigee 338 km, and inclination 51.65 deg.
MSAT 1 is a Canadian geostationary mobile telephone communications
spacecraft that was launched by an Ariane 42P rocket from Kourou,
French Guiana, to serve the North American continent. The spacecraft
and its transponders are very similar to those of the American
ASTRA 1F is a European (SES, Luxembourg) geosynchronous
communications spacecraft that was launched by a Proton-K rocket
from Baykonur cosmodrome at 23:09 UT. The 3,010 kg spacecraft is to
be parked over 19.2 deg E-longitude to provide direct broadcast TV
to Europe through its 16 Ku-band transponders.
INMARSAT 3-F1 is a geosynchronous communications spacecraft of the
79 nation consortium and was launched by an Atlas 2A rocket from
Cape Canaveral Air Station. The 2,068 kg spacecraft will provide
telephone links to airlines and passengers through its five L-band beams
after parking at 64 deg E-longitude.
USA 117 is the latest addition to the Navstar/GPS series of
navigational spacecraft. The GPS series is listed in section C-2.
Initial orbital parameters were period 718 min, apogee 20,282 km,
perigee 20,078 km, and inclination 54.7 deg.
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. To see a list select here.
- Global Positioning System satellites useful for navigational
purposes and geodetic studies. To see a list select here.
The GPS 2-NN series orbits in six distinct planes that are about 60 deg apart.
Each plane has five "slots." Following are the 2-NN members in the planes/slots.
The RAAN decreases by about 1.0 deg each month; below are their
approximate RAAN longitudes in November 1995.

- Russian Global Navigational (Positioning) Spacecraft, GLONASS
constellation. To see a list select here.
The GLONASS NNN series orbit in three distinct planes that are 120
deg apart. Each plane has eight "slots". Following are the members of
Plane 1 Plane 2 Plane 3

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
Code 633, NASA/GSFC, Greenbelt, Maryland 20771, U.S.A., for specific
information (REQUEST@NSSDCA.GSFC.NASA.GOV). 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
