2002-024A, 2002-024B Payload A and Payload B are the tentative names for the two Chinese (PRC) satellites that were launched by a Long March 4B rocket from Taiyuan Launch Center on 5 May 2002 at 01:50 UT. (There are three operational launch centers in China: Jiuquan in Gansu province in the northwest, Taiyuan in Shanxi province in the north, and Xichang in Sichuan province in the southwest.) One of them is the weather satellite Fengyun 1D (meaning Wind and Cloud 1D), and the other is Haiyang 1 (Marine 1).

The 428 kg Fengyun 1D carries an Earth Imager that will digitally photograph clouds, rivers and, lakes and forewarn river floods and sand storms.

The 360 kg Haiyang 1 carries an Ocean Imager in sevral visible and infrared bands to study ocean temperature, chlorophyll concentration, sedimentation, and ecology. The analysis will involve auxilliary data from buoys, marine planes and coastal observation stations.

2002-021A SPOT 5 is a French (CNES), Earth-imaging, three tonne satellite that was launched by an Ariane 42P rocket from Kourou at 00:31 UT on 4 May 2002. Its planar and stereoscopic relief images at about three meter resolution will be marketted for civilian and military uses, for cartographic and vegetation analyses. Panchromatic (at 2.5 m resolution) as well as multispectral images (at 10 m resolution) could be obtained. The position of the satellite, and hence the location of the imges could be determined at 15 m accuracy by means of the DORIS position determination instrument. Extensive information on the instruments and data products is available via http://www.spotimage.com/home/. The initial orbital parameters were period 101.4 min, apogee 826 km, perigee 825 km, and inclination 98.8 deg.

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 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.

  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 (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.

    4e 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.

    The latest addition to the GLONASS fleet are Cosmos 2380, Cosmos 2381, and Cosmos 2382.

  4. Visually bright objects.

    A comprehensive list of visually bright objects with their two-line orbital elements is available from USSPACECOM, via a NASA site, 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.
