|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.
The initial orbital parameters of both were very close: period 102.2 min, apogee 872 km, perigee 851 km, and inclination 98.8 deg.

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.

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)

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.
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.
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.
