B. Text of Launch Announcements.
DBS 3, an American geostationary communications spacecraft
owned by DirectTV Inc., was launched by an Ariane 42-P
rocket from Kourou in French Guiana at 00:24 UT. After
reaching the parking longitude of 100.8-W, it will provide 30

a Tsiklon-2 rocket at 04:43 UT from Baykonur cosmodrome. Initial
orbital parameters were period 92.7 min, apogee 417 km, perigee 403
km, and inclination 65.0 deg.
USA 111 is an American military spacecraft. Initial orbital
parameters were period 461 min, apogee 26,508 km, perigee 290 km, and
inclination 27.0 deg.
Cosmos 2312, a Russian military communications spacecraft, was
launched by a Molniya-M booster from Plesetsk cosmodrome at 20:10
UT. Initial orbital parameters were period 708 min, apogee 39,275 km,
perigee 602 km, and inclination 62.9 km
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.
