B. Text of Launch Announcements.

2004-043A
Express-AM1 is a Russian geostationary communications satellite that was launched by a Proton-M rocket from Baikonur at 22:11 UT on 29 October 2004. It will provide digital TV, radio broadcasting, video-conference, and wide-band internet services to most of Russia. Parking longitude is not available at this time.
2004-042A
Fengyun 2C is a Chinese (PRC) geostationary weather satellite that was launched by a Long March 3A rocket from Xichang Satellite Launch Center in Sichuan province at "09:30 a.m." (probably 01:30 UT) on 19 October 2004. The 1.38 tonne satellite carries imagers in visible and infra-red bands to monitor droplet sizes on cloud tops, ocean temperature, dust storms and forest fires over one-third of the global surface, after parking over 105° E longitude.
2004-041A
AMC 15, also known as AMERICOM 15 is an American geostationary communications satellite that was launched by a Proton-M rocket from Baikonur at 21:23 UT on 14 October 2004. The 4.05 tonne satellite carries 24 Ku-band transponders and 12 spot-beam, Ka-band transponders to provide direct-to-home video, voice, and internet services to North America after parking over 105° W longitude.
2004-040A
Soyuz-TMA 5 is a Russian automatic passenger transportation craft that was launched by a Soyuz-U rocket from Bailkonur at 03:06 UT on 14 October 2004. It carried two Russian and one American astronaut to the International Space Station (ISS). It docked with the PIRS module of the ISS at 04:25 UT on 16 October with manual control by the commander after it was determined to be approaching the ISS at an excessive speed. Two of the astronauts will spend a six-month residency at the station. The third, along with the two astronauts who had spent six months in ISS soft-landed on 24 October in Russia on the Soyuz-TMA 4 which had remained docked for six months. The initial orbital parameters of TMA 5 were period 87.1 min, apogee 367 km, perigee 355 km, and inclination 51.6°.

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.

NNSS denotes U.S. Navy Navigational Satellite System. Updates or corrections to the list are possible only with information from the user community.

Note: The full list appeared in SPX 545. The list will not be repeated in future issues until significantly revised again.

Global Positioning System satellites useful for navigational purposes and geodetic studies.

High precision (<20 cm) GPS constellation tracking data obtained from the network of about 400 dedicated global stations that are of interest to geodetic study may be obtained through the following services provided by the International GNSS Service (IGS). The IGS is a service of the International Association of Geodesy (IAG).

The standard format of the GPS situation appeared in SPACEWARN Bulletin No. 518. It will not be repeated since an excellent source of trajectory- and science-related GPS information is at:

http://www.colorado.edu/geography/gcraft/notes/gps/gps_f.html

It provides many links to GPS related databases.

The latest addition to the fleet is Navstar 54, 2004-009A.

Russian Global Navigational (Positioning) Spacecraft, GLONASS constellation.

SPACEWARN requests updates/additions from readers to this list.

All GLONASS spacecraft are in the general Cosmos series. The Cosmos numbers invoked by USSPACECOM have often differed from the numbers (NNNN) associated in Russia; when different, the USSPACECOM Cosmos numbers are shown in parentheses. The corresponding GLONASS numbers are Russian numbers, followed by the numbers in parentheses that are sometimes attributed to them outside Russia.

The operating frequencies in MHz are computed from the channel number K. Frequencies (MHz) = 1602.0 + 0.5625K and L2 = 1246.0 + 0.4375K.

The standard format of the GLONASS situation last appeared in SPACEWARN Bulletin No. 545. It will not be repeated in view of the excellent updated source at: http://www.glonass-ianc.rsa.ru/ maintained by the Information-Analytical Center (IAC), Russian Space Agency.
