2007-021A   SinoSat 3 is a Chinese (PRC) geostationary communications satellite that was launched by a Long March 3A rocket from Xichang at 16:08 UT on 31 May 2007. It carries 10 C-band transponders to provide voice and video links to much of eastern Asia, after parking over 125° E longitude.   2007-020A,  2007-020C,  2007-020D,  2007-020F   Globalstar-A, Globalstar-B, Globalstar-C, and Globalstar-D are the latest four American Globalstar communications satellites in the Globalstar fleet that were launched by a Soyuz-Fregat rocket from Baikonur at 20:31 UT on 29 May 2007. They are also known as Globalstar FM65, Globalstar FM69, Globalstar FM71, and Globalstar FM72, respectively. These second-generation craft each have a dry mass of 350 kg like the older 52 craft in the fleet, providing two-way transmission of voice and data from mobile and fixed stations. The initial orbital parameters of all four were similar: period 103.5 min, apogee 923 km, perigee 905 km, and inclination 52°.   2007-019B   PicoSat is only a generic name for the 1.0 kg craft that was launched with Yaogan 2 (2007-019A). It will validate design of microelectronic components. It was launched by a Long March 2D rocket from Jiuquan Satellite Launch Center at 07:12 UT on 25 May 2007. The initial orbital parameters were period 97.6 min, apogee 655 km, perigee 631 km, and inclination 97.85°.   2007-019A   Yaogan 2 is a Chinese (PRC) remote-sensing craft that was launched by a Long March 2D rocket at 07:12 UT on 25 May 2007. The data from it will help in crop estimates and disaster alert/remedy efforts. The initial orbital parameters were period 97.6 min, apogee 655 km, perigee 631 km, and inclination 97.85°.   2007-018A   NigComSat is a Nigerian geostationary communications satellite that was launched by a Long March 3B rocket from Xichang launch center on 13 May 2007. The 5.2 tonne (with fuel) craft carries four C-band, 18 Ku-band, four Ka-band, and two L-band transponders to provide voice, video, and data links to all of Africa, and southern Europe after parking over 42.5° E longitude.   2007-017A   Progress-M 60 is a Russian automatic cargo carrier that was launched by a Soyuz-U rocket from Baikonur at 03:25 UT on 12 May 2007. It is also known as Progress 25, presumably belonging to the new model. It carried 45 kg of air, 419 kg of water, and 1.4 tonne of dry cargo, 241 kg of fruits and vegetables, 136 kg of medical equipment. It docked automatically with the Zarya module of the ISS at 05:10 UT on 15 May 2007.   2007-016B   Galaxy 17 is an American geostationary communications satellite that was launched by an Ariane 5ECA rocket from Kourou at 22:29 UT on 04 May 2007. The 4.1 tonne (with fuel), 9.5 kW craft carries 24 C-band and 24 Ku-band transponders to provide telephone and television services to South and North America and Europe, after parking over 74° W longitude.   2007-016A   Astra 1L is a European (Luxembourg-based) geostationary communications satellite that was launched by an Ariane 5ECA rocket from Kourou at 22:29 UT on 04 May 2007. The 4.5 tonne (with fuel) craft carries 29 Ku-band and two Ka-band transponders to provide video and voice links direct-to-home in all of Europe, after parking over 19.2° E longitude.  

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.
