B. Text of Launch Announcements.
Cosmos 2278, a Russian spacecraft, was launched by a
Zenit-2 rocket from Baykonur cosmodrome at 08:02 UT.
Initial orbital parameters were period 102 min, apogee 880.8 km,
perigee 852.0 km, and inclination 71.0 deg.
GOES 8, a U.S.A. meteorological geostationary spacecraft, was
launched by an Atlas 1 rocket from Cape Canaveral at 20:04
UT. On board were instruments for high resolution visible
and UV imagers, and "sounders" for temperature and
moisture profiles. Also on board were energetic particle
detectors and a magnetometer.
1994-021C, -021B, -021A
Cosmos 2277, 2276, and 2275, the triplet of Russian
spacecraft, were launched by a Proton-K rocket from Baykonur
cosmodrome at 08:49 UT. They are part of the GLONASS fleet of
global positioning satellites, similar to the NAVSTAR-GPS fleet
of USA spacecraft. With these three, GLONASS has 15 operational
members. Initial orbital parameters of all three were
period 676.6 min, apogee 19,197 km, perigee 19,120 km, and
inclination 64.8 deg.
STS 59, a USA shuttle spacecraft, was launched from Cape
Canveral. It carried synthetic aperture radars at three
wavelengths: 23 cm (C-band), 6 cm (C-band), and 3 cm
(X-band). For each wavelength, there was an array of
six, electronically steerable antenna panels; the polarization
plane of the emitted radiation could be varied as needed. It
was expected to cover 48 million square kilometers of terrain and
vegetation, yielding 32 trillion bits of data for capturing
in 183 high-density tapes on board. Initial orbital parameters
were period 88.7 min, apogee 218 km, perigee 204 km, and
inclination 56.9 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 orbit in six distinct planes that are 60 deg apart.
Each plane has four "slots." Following are the members of the planes/slots:
PLANE RAAN OF PLANE SLOT-1 SLOT-2 SLOT-3 SLOT-4
A 269 2-21 2-12 2-15 2-04
B 329 2-18 2-07 2-02 2-22
C 29 2-23 2-13 2-19 2-20
D 89 2-11 2-09 2-05 ----
E 149 2-01 2-08 2-03 2-10
F 209 2-16 2-14 2-06 2-17
- Actual decays/landings of payload spacecraft and rocket bodies (R/B)
only. Additional information is not available.
