A. List of New International Designations and Launch Dates (UTC).

    INT.ID    CAT. #      NAME                   DATE (UT)
   2005-023A    28707     Express-AM3           24 June 2005
   2005-022A    28702     Intelsat Americas 8   23 June 2005

B. Text of Launch Announcements.

Express-AM3 is a Russian geostationary communications satellite that was launched by a Proton-K rocket from Baikonur at 20:41 UT on 24 June 2005. The 2.5 tonne satellite carries 16 C-band, 12 Ku-band, and a single L-band transponders to provide video and radio transmissions to all of Russia after parking over 140°E longitude. The Express-AM fleet is replacing the aging fleets of Gorizont and Ekron-M.
Intelsat Americas 8 (also known as IA 8) is an American (Bermuda registered) geostationary satellite that was launched by a Zenit 3SL rocket from Odyssey, the platform floating on the equatorial Pacific Ocean at 154°W longitude, at 15:03 UT on 23 June 2005. The 5.5 tonne, 16 kW satellite carries 28 C-, 36 Ku-, and 24 Ka-band transponders to provide video and data transmissions to all countries in North and South America, after parking over 89°W longitude. It will be the 28th satellite in the Intelsat fleet.
Progress-M 53 is a Russian automatic cargo craft that was launched at 23:09 UT on 16 June 2005 by a Soyuz-U rocket from Baikonur. The craft carried 2.5 tonnes of food, water, fuel, and supplies to the International Space Station (ISS). It docked with the Zvezda module of the ISS "manually" (after a glitch in a communications link) at 00:44 UT on 18 June, with commands from the Russian astronaut on-board the ISS. In anticipation of the docking, the previously docked Progress-M 52, carrying over a tonne of garbage from the station, was evicted from its port to deorbit into the Pacific Ocean. The initial orbital parameters of Progress-M 53 were period 91 min, apogee 353 km, perigee 351 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:

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: maintained by the Information-Analytical Center (IAC), Russian Space Agency.

A Russian-American satellite named Cosmos 1 was launched from a Russian submarine in the Barents Sea on 21 June 2005 by a modified ICBM. The 103 kg satellite was equipped with eight triangular sails of side 15 m that would navigate the satellite by solar radiation pressure alone. However, the satellite crashed soon after, and some debris were later located in the sea.

A Russian Molniya-M rocket, carrying a military satellite, was launched from Plesetsk at 00:49 UT on 21 June 2005. The rocket crashed in Siberia soon after lift-off.
