2002-025A OFEQ 5 is an Israeli military photo-reconnaissance satellite that was launched westward (i.e., retrograde) from Palmahim Beach AFB on the Mediterranean coast by a Shavit rocket at 14:55 UT on 28 May 2002. The initial orbital parameters were period 96 min, apogee 770 km, perigee 369 km, and inclination 143.5°.
2002-024A, 2002-024B Payload A and Payload B are the tentative USSPACECOM names for the two Chinese (PRC) satellites that were launched by a Long March 4B rocket from Taiyuan Launch Center on 15 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 several 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.

The Team Leader is Moustafa Chahine, JPL. The data will be distributed through the GSFC-DAAC, NASA, Greenbelt, MD., USA. The URL, http://orbit-net.nesdis.noaa.gov/crad/st/amsuclimate/amsu.html provides additional information.

AIRS (Atmospheric Infrared Sounder) is a 156 kg, 256 W NASA/JPL instrument that measures global temperatures, cloud properties and radiated flux in 2,300 spectral bands covering wavelengths in the 0.4-1.7 and 3.4-15.4 micron ranges. Altitude resolution is 1 km and the temperature accuracy is at 1.0 K. The Team Leader is Moustafa Chahine, JPL. The data will be distributed through the GSFC-DAAC, NASA, Greenbelt, MD. USA.

HSB (Humidity Sounder from Brazil) is an INPE/Brazil, 66 kg, 85 W instrument that measures atmospheric humidity in four frequency channels at a horizontal spatial resolution of 13.5 km. One channel is at 150 GHz and three are near 183 GHz. The Team Leader is Moustafa Chahine, JPL. The data will be distributed through the GSFC-DAAC, NASA, Greenbelt, MD., USA. For more details see, http://aqua.nasa.gov/.

CERES (Clouds and Earth Radiant Energy System) is a NASA/LaRC, 100 kg, 104 W instrument that monitors radiated energy flux in the 0.3-5.0, 8-12, and 03-50 micron range, at a spatial resolution of 20 km. The Team Leader is Bruce Wielicki, LaRC. The data will be distributed through the Langley-DAAC, LaRC, NASA, Hampton, VA, USA.

The initial orbital parameters of AQUA were period 98.4 min, apogee 686 km, perigee 673 km, and inclination 98.2°.
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 marketed 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 images 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°.

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.

  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.

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