B. Text of Launch Announcements.

2003-061A Double Star 1 (also known as Tan Ce 1, and TC 1) is a Sino-European (CNSA-ESA) satellite that was launched by a Long March 2C/SM rocket from Xichang Satellite Launch Center in the Sichuan province of China (PRC) at 19:06 UT on 29 December 2003. The 330 kg, 260 W satellite is cylindrical, with a diameter of 2.1 m, a height of 1.4 m, and spins at a rate of 15 rpm. It carries eight instruments to probe Earth's magnetosphere, five from ESA and three from CNSA. (The ESA instruments are legacies from ESA's Cluster mission.) The data from all instruments will be stored on-board and dumped over three ground stations: Shanghai and Beijing in China, and Villafranca in Spain. The Program Manager is Bodo Gramkow (ESA) and the Project Scientist is Philippe Escoubet (ESA). There will be coordination between the Cluster and Double Star missions. For more information, see http://www.esa.int/export/esaSC/120381_index_0_m.html. Initial orbital parameters were period 1,644 min, apogee 78,970 km, perigee 562 km, and inclination 28.23°.

ASPOC (Active Space Potential Control) is to maintain the potential of the spacecraft at a low voltage. The tendency to attain high positive voltage due mainly to photoelectric emission is sought to be neutralized by shooting out positive indium ions. The spacecraft potential is continuously monitored by the PEACE instrument. The Principal Investigator is K. Torkar, IWF, Graz, Austria.

PEACE (Plasma Electron And Current Experiment) infers the positive potential of the spacecraft by counting the number and speed of the thermal electrons that impinge on it. This measurement is an input to the operation of ASPOC. The Principal Investigator is A. Fazakerley, MSSL, Dorking, UK.

FGM (Flux Gate Magnetometer) is located on a 3.5 meter long boom and measures the magnetic field along the orbit at a rate up to 67 samples per second. The Principal Investigator is Chris Carr, IC, UK.

HIA (Hot Ion Analyzer) measures the distribution function of ions in the magnetosphere and the solar wind, during each spin period of four seconds. The Principal Investigator is Henri Reme, CESR, Toulouse, France.

STAFF-DWP (Spatio-Temporal Analyzer of Field Fluctuations and Digital Wave Processor) The data from the magnetometer consists of two components. The low frequency components are transmitted to the ground for analysis. The higher frequency components are best analyzed on-board by a DWP and STAFF and the result telemetered to the ground stations. The Principal Investigators are N. Cornilleau-Wehrlin of CETP, Velizy, France; and H. Alleyne, Sheffield University, UK.

HEED (High Energy Electron Detector) measures the flux of energetic electrons in the magnetosphere. The Principal Investigators are W. Zhang and J. B. Cao of CSSAR, China. (CSSAR stands for Center for Space Science and Applied Research of the Chinese Academy of Sciences, Beijing)

HEPD (High Energy Proton Detector) detects energetic protons in the magnetosphere and solar wind. The Principal Investigators are J. Liang and J. B. Cao, CSSAR, China.

HID (Heavy Ion Detector) detects heavy ions of AMU>4. The Principal Investigators are Y. Zhai and J. B. Cao, CSSAR, China.
2003-060A Express AM-22 is a Russian geostationary communications satellite that was launched by a Proton-K rocket from Baikonur at 23:00 UT on 28 December 2003. The 2.6 tonne, 6 kW satellite will provide television, internet and data transmissions to Russia and bordering countries through its 24 Ku-band transponders, after parking over 53°E longitude.
2003-059A AMOS 2 is an Israeli geostationary communications satellite that was launched by a Soyuz-Fregat rocket from Baikonur at 21:30 UT on 27 December 2003.

2003-058A Navstar 53, also known as USA 175, as GPS 2R-10, and as SVN-47, is an American navigational satellite in the GPS fleet. It was launched by a Delta 2 rocket from Cape Canaveral AFS at 07:50 UT on 21 December 2003. It will replace the aging but still operational GPS 2A-10 craft in Plane-E and Slot-2. (The GPS constellation consists of 24 satellites split into six orbital planes with four in each plane, all in circular orbits of altitude 20,200 km, and inclination of 55°. There are also four additional satellites orbiting as reserves. The full list is available at http://leonardo.jpl.nasa.gov/msl/Programs/gps.html.) Initial orbital parameters of Navstar 53 were period 716.5 min, apogee 20,327 km, perigee 19,966 km, and inclination 55.1°.
2003-057A UFO 11, also known as USA 174, is an American geostationary military communications satellite that was launched by an Atlas 3 rocket from Cape Canaveral at 02:30 UT on 18 December 2003. ("UFO" has been identified as the acronym for Uhf Follow-On.) The 1.4 tonne satellite is the eleventh and final of the UFO constellation which provide secure communications in UHF band of frequencies among ships, aircraft, mobile ground terminals even during severe weather conditions. It wll be parked at 172°E longitude.

  2003-056C
Cosmos 2402, Cosmos 2403, and Cosmos 2404 are the latest additions to the Russian fleet of Glonass navigational satellites. One of the good websites for the Glonass fleet is http://gge.unb.ca/Resources/GLONASSConstellationStatus.txt. The initial orbital parameters of all these three were, approximately, period 672 min, apogee 19,105 km, perigee 18,965 km, and inclination 65.1°.
2003-055A Gruzomaket is a Russian satellite that was launched by a Strela rocket (a modified SS-19 ICBM) from Baikonur. No further information could be ascertained except that the Russian Interfax news agency calls the payload as a mockup (and the name can be so translated also). Initial orbital parameters were period 93.7 min, apogee 462 km, perigee 453 km, and inclination 67.1°.
2003-054A USA 173 is an American military satellite (operated by the National Reconnaissance Office) that was launched by an Atlas 2AS rocket from Vandenberg AFB at 10:04 UT on 2 December 2003. It is reported to be part of the NOSS (Naval Ocean Surveillance System) fleet.
2003-053A, 2003-053F Yamal 202 and Yamal 201 are a pair of Russian geostationary communications satellite that were launched by a Proton-K rocket from Baikonur at 06:22 UT on 24 November 2003. They are identical satellites, with a mass of 1.3 kg, and power 3.6 kW. Yamal 201 carries nine C-band and six Ku-band transponders, while Yamal 202 carries 18 C-band transponders. They will provide voice and video communications throughout the Eurasian continent, after parking: Yamal 201 at 90°E and Yamal 202 at 49°E.
2003-022C Beagle 2 is an ESA Mars Lander that was released from the orbiting Mars Express (2003-022A, launched on 2 June 2003) on 19 December 2003. It was to soft-land on Mars 25 December 2003. Effort is still ongoing to receive signals from Beagle 2. The instruments on board Beagle 2 are described under Mars Express in SPX.596.

C. Spacecraft Particularly Suited for International Participation

  1. 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.

  2. 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 53, 2003-058A.

  3. 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.
