B. Text of Launch Announcements.
Molniya 3-47 is a Russian communications spacecraft that
was launched by a Molniya-M booster from Plesetsk cosmodrome at
03:21 UT. It is expected to provide voice and TV coverage for
a wide area between western Europe and eastern Siberia. Initial
orbital parameters were period 13 hr, 17 min, apogee 40,851 km,
perigee 472 km, and inclination 62.8 deg.
KOREASAT 1, also known as MUGUNGHWA 1 is a South Korean
communications spacecraft that was launched by a Delta-2 rocket
from Cape Canaveral at 11:10 UT. It carries 15 Ku-band transponders
to provide TV coverage for South Korea and other Asian countries.
The final stage of the rocket failed to separate from the
spacecraft which, therefore, failed to achieve a geostationary orbit.
Plans are to use up some of the reserved fuel to move it to the
geostationary orbit (over the Solomon Islands); this fuel loss will
entail a reduced operational lifetime. Initial orbital parameters
were period 17.7 hr, apogee 29,798 km, perigee 26,777 km, and
inclination 0.07 deg.
PANAMSAT 4, also known as PAS 4, is an American geostationary
spacecraft that was launched by an Ariane rocket from Kourou in
French Guiana at 22:58 UT. The 3,043 kg spacecraft carries 16
30-Watt C-band transponders and 24 60-Watt Ku-band transponders,
and is expected provide 320 radio channels and 120 "DirecTV"
channels. The parking longitude is 69 deg, E.
Magion 4, sometimes known as S2-X or S2-T, is a Czech subsatellite
of the Russian Interball Tail, and was released from it 9 hr, 21 min
after its launch. The 50 kg subsatellite carries a number of
instruments: two for plasma measurements, three for E/B waves,
three for energetic particles/x-rays, and a magnetometer. Initial
orbital parameters were very close to those of Interball Tail; it
will be maneuvered to remain at desired locations within 100,000 km
from the main spacecraft.
Interball Tail (occasionally refered to as INTERBOL 1, or Prognoz M2)
is a Russian spacecraft that was launched at 23:59 UT from Plesetsk
cosmodrome by a Molniya-M booster. The 1,250 kg spacecraft carried
many instruments: five for energetic particles/x-rays, nine for E/B
fields and waves, and eight for cold/hot plasma. It released
the subsatellite Magion 4 after nine hours into flight. Both
spacecraft are part of the multinational ISTP program. Initial
orbital parameters were period 91 hr, apogee 192,000 km, perigee 776
km, and inclination 63 degrees.
USA 113, also known as DSCS 3, is an American military spacecraft
that was launched by an Atlas-2A rocket at 11:30 UT from Cape
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 orbit in six distinct planes that are about 60 deg apart.
Each plane has four "slots." Following are the 2-NN members in the planes/slots.
The RAAN decreases by about 1.0 deg each month; below are their
24 May, 95 RAAN longitudes.
