|2000-049A||Raduga-1 5 is a Russian military communications geosynchronous spacecraft that was launched by a Proton-K rocket from Baikonur at 20:27 UT. The spacecraft also has the alternative names Cosmos 2372 and Globus-1. There are many Radugas still in orbit, but only about five of them are operational.|
|2000-048A||DM-F3 is an American dummy satellite that was used to test the launch capability of the new model Delta 3 rocket. It was launched from Cape Canaveral at 11:05 UT. The 4,300 kg dummy is a two-meter diameter steel spool on which the US Air Force had marked black stripes to enable a novel tracking technique. Initial orbital parameters were period 361 min, apogee 20,634 km, perigee 192 km, and inclination 27.6 deg.|
|2000-047A||USA 152 is an American radar-imaging military/NRO satellite that was launched by a Titan 4B rocket from Vandenberg AFB at 23:45 UT. It is the fourth in the Lacrosse series, and is probably a replacement for the aging Lacrosse 2.|
|2000-046B||Nilesat 102 is an Egyptian geosynchronous communications spacecraft that was launched by an Ariane 44LP rocket from Kourou at 23:16 UT. The 1,827 kg (with fuel) spacecraft carries 12 Ku-band 100 W transponders to provide digital communications for countries in North Africa and Middle East, after parking over 7 deg-E.|
|2000-046A||Brazilsat B4 is a Brazilian geosynchronous communications spacecraft that was launched by an Ariane 44LP rocket from Kourou at 23:16 UT. The 1,757 kg (with fuel) spacecraft carries 28 C-band transponders to provide voice and video communications to the entire South American continent after parking over 92 deg-W.|
|2000-045A, 2000-045B||Cluster 2/FM5 (Rumba) and Cluster 2/FM8 (Tango)
are the second
pair of the Cluster quadruplet that were launched by a Soyuz-Fregat
rocket from Baikonur at 11:13 UT. The spacecraft and their
payloads are identical to those of the earlier Cluster pair
(2000-041A, 2000-041B) reported in
and will not be repeated here.
The orbits of all these four will be frequently maneuvered so as
to achieve the targeted investigations. For ongoing updates
of orbital information and other status, see
Initial orbital parameters of both were similar: period
3,426 min, apogee 120,500 km, perigee 17,200 km, and inclination
Note: This is to summarize the nomenclature for the recently launched Cluster spacecraft.

Note that NSSDC will carry the name "Cluster96" in its information files to designate the unsuccessful 1996 four-spacecraft launch.

|2000-044A||Progress M1-3 is a Russian automatic cargo carrier that was launched by a Soyuz-U rocket from Baikonur at 18:26 UT. It carried 1.5 tonnes of fuel, and 615 kg of various equipment, water, and food to deliver to the Zvezda module of the ISS. It docked with Zvezda at 08:56 UT on 8 August. The cargo will be unloaded into Zvezda when an American shuttle arrives with a Russian-American crew in September 2000. Initial orbital parameters were period 91.8 min, apogee 369 km, perigee 357 km, and inclination 51.6 deg.|
Note: The full list appeared in SPX 545. The list will not be repeated in future issues until significantly revised again.
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.
The latest addition to the GPS fleet is Navstar 48 (USA 151).
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.

USSPACECOM has now the final, matching names and numbers for the following spacecraft:
These correspond to what were reported in SPX 561, but not to the late-July revision by USSPACECOM.
NSSDC/WDC for Satellite Information is an archival center for science
data from many spacecraft. Many space physics datasets are on-line for
electronic access through:
For off-line data, please contact the Request Office, NSSDC, Code 633, NASA GSFC, Greenbelt, Maryland 20771, U.S.A., for specific information (email@example.com). Information on the current status of the instruments on board from the investigators will be most welcomed. Precomputed trajectory files and orbital parameters of many magnetospheric and heliospheric science-payload spacecraft may be accessed via anonymous FTP from NSSDC. (See About the SPACEWARN Bulletin for access method; a file in the active directory named AAREADME.TXT, outlines the contents.)
