B. Text of Launch Announcements.

1993-073B
METEOSAT 6, a European meteorological spacecraft, was launched by an Ariane 44 LP rocket from Kourou, French Guiana, at 01:17 UT.

1993-073A
SOLIDARIDAD-1, a Mexican geostationary communications spacecraft, was launched by an Ariane 44 LP rocket. It will cover regions north of Mexico in the Ku-band and regions southward in C-band.

1993-072A
Gorizont 29, a Russian geostationary communications spacecraft, was launched by a Proton rocket from Baykonur cosmodrome. Orbital parameters are period 23 hr 19 min, apogee 35,088 km, perigee 35,037 km, and inclination 1.4 deg. The parking longitude is 130 deg east.

1993-071A
Cosmos 2267, a Russian spacecraft, was launched by a Soyuz rocket from Plesetsk cosmodrome. Initial orbital parameters are period 89 min, apogee 279 km, perigee 198 km, and inclination 70.4 deg.

1993-070A
Cosmos 2266, a Russian spacecraft, was launched from Plesetsk cosmodrome by a Cosmos rocket at 13:10 UT. Initial orbital parameters are period 108 min, apogee 1,031 km, perigee 967 km, and inclination 82.9 deg.

1993-069A
Gorizont 28, a Russian geostationary communications spacecraft, was launched by a Proton rocket from Baykonur cosmodrome. It will provide telephone and TV communications to Siberia and the Far East. Orbital parameters are period 23 hr 55 min, apogee 35,788 km, and perigee 35,354 km, and inclination 1.4 deg. The parking longitude is 90 deg east.

1993-068A
USA 96, also known as GPS-2-23, was launched from Cape Canaveral AFB by a Delta 2 rocket. It is the twenty-third member of a full constellation of 24 spacecraft. A publicly available frequency channel will enable navigational accuracy of 100 meters, while an encrypted channel will enable the military a more accurate capability. Orbital parameters are period 718 min, apogee 20,264 km, perigee 20,107 km, and inclination 55.08 deg.

1993-067A
Cosmos 2265, a Russian spacecraft, was launched from Plesetsk cosmodrome by a Cosmos rocket at 13:00 UT. Initial orbital parameters are period 104 min, apogee 1,592 km, perigee 301 km,and inclination 82.9 deg. The rocket was a modified combat missile, with the environmental toxicity of the fuel reduced by a factor of 10.

C. Spacecraft Particularly Suited for International Participation

Category I
  1. 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.

  2. 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:
