B. Text of Launch Announcements.

2001-012A XM 2 (better known as XM Rock) is an American geosynchronous radio broadcast satellite that was launched by a Zenit 3SL rocket from the Sea Launch Platform on the equatorial Pacific ocean at 22:33 UT. The 4.7 tonne (with fuel), 18 kW satellite carries two transmitters (3 kW each) in the S-band to relay 100 channels of digital quality music uplinked in the X-band from one or more ground stations, after parking over 115 deg-W longitude. (It will be accompanied by XM Roll due to be launched in May 2001.) The investors include several auto manufacturers who will be equipping the special receivers in their models.
2001-011B BSat 2A is a Japanese geosynchronous communications spacecraft that was launched by an Ariane 5 rocket from Kourou at 22:51 UT. The 1.3 tonne (with fuel) satellite will be parked over 110 deg-E longitude to provide direct-to-home voice, video and internet communications.
2001-011A Eurobird is the 18th member of the European Eutelsat consortium's geosynchronous constellation that was launched by an Ariane 5 rocket from Kourou at 22:51 UT. It carries 24 Ku-band transponders to provide broad bandwidth and high power direct-to-home transmissions to enable digital entertainment and internet connections. The three tonne (with fuel) satellite will be parked over 28.5 deg-E longitude, replacing the aging Copernicus (presumably, an alternative name for Kopernikus (DFS 3), 1992-066A)
2001-010A STS 102 is an American shuttle spacecraft that was launched from Cape Canaveral at 11:42 UT. It carried a crew of seven astronauts (six American and one Russian). The primary mission was to deliver a multi-rack Italian container (Leonardo MultiPurpose Logistics Module, LMPLM) to the Destiny Module of the International Space Station, ISS. It docked with the ISS at 05:34 UT on 9 March. The 6.4 m x 4.6 m cylindrical LMPLM delivered new equipment to Destiny, and retrieved used/unwanted equipment, and trash back to the shuttle. The crew did a few spacewalks to install a platform on the ISS to support a Canadian robot arm when it arrives next month. The STS 102 left behind three of the astronauts (two American and one Russian) and brought back the three astronauts (one American and two Russian) who had been inhabiting the ISS for about four and a half months, when it landed at Cape Canaveral at 07:31 UT on 21 March.

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. ("NNN" denotes no national name. SPACEWARN would appreciate suggestions to update this list. An asterisk [*] denotes changes in this issue.)

    High precision (<20 cm) GPS constellation tracking data obtained from the network of about 80 dedicated global stations that are of interest to geodetic study may be obtained through the following services provided by the International Association of Geodesy (IGS)

         FTP:    igscb.jpl.nasa.gov  [directory /igscb]
         WWW:    http://igscb.jpl.nasa.gov/
         E-mail: igscb@cobra.jpl.nasa.gov
    

    The standard format of the GPS situation appeared in SPX-518. It will not be repeated since an excellent source of trajectory- and science-related GPS information is at http://www.utexas.edu/depts/grg/gcraft/notes/gps/gps.html#DODSystem It provides many links to GPS related databases.

    The latest addition to the GPS fleet is Navstar 50 (2001-004A).

    An e-mail communication from Richard B. Langley is available which provides a status of the Navstar GPS Constellation as of 24 March 2001.

  3. Russian Global Navigational (Positioning) Spacecraft, GLONASS constellation. (SPACEWARN requests updates/additions from readers to this list. Entries marked "*" are updates or additions to the list.)

    All GLONASS spacecraft are in the general COSMOS series. The COSMOS numbers (nnnn) 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 appeared in SPX-545. It will not be repeated in view of the excellent updated source at: http://www.rssi.ru/SFCSIC/english.html maintained by the Coordinational Scientific Information Center (CSIC),Russian Space Forces.

  4. Visually bright objects.

    A comprehensive list of visually bright objects with their two-line orbital elements is available from USSPACECOM, via a NASA URL, http://oig1.gsfc.nasa.gov/files/visible.tle. The list, however, does not include visual magnitudes, but are expected to be brighter than magnitude 5.

  5. Actual decays/landings of payload spacecraft and rocket bodies (R/B) only. No further information is available.
