The last full list appeared as a part of SPX 520. The list will reappear only after major updates to the list are available.
METEOSAT 3 in that list is no longer operational.
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 member of the GPS fleet is NAVSTAR 38 (1997-067A), launched on 6 November 1997.

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-515. It will not be repeated in view of the excellent updated source at: http://www.rssi.ru/SFCSIC/glonass.html maintained by the Coordinational Scientific Information Center (CSIC),Russian Space Forces.

Erratum. In SPX 528, Section B it was reported that STEP-1, STEP-2, and STEP-3 were launch failures. TRW Inc. has now reported that STEP-2 launch was not a failure, and that it had been operational during its planned life time.
Erratum. Due to an error during editing, the spacecraft names and numbers were misaligned by one line in the hardcopy version of the SPX 529. The on-line versions carry the correct list.
India purchased ARABSAT 1C from that consortium and moved it to the parking longitude of 55 deg-E; it was then renamed INSAT 2DT and became operational to carry out the relays in place of INSAT 2D, which became inoperational about two months ago. INSAT 2DT carries 25 C-band transponders and one S-band transponder.
NSSDC/WDC-A-R&S is an archival center for science data from many spacecraft.
Some data are on line for electronic access. Please contact the NSSDC Request Coordination
Code 633, NASA/GSFC, Greenbelt, Maryland 20771, U.S.A., for specific
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 FTP'ed from NSSDC's ANON_DIR:[000000.ACTIVE] and its
several subdirectories. (See About the SPACEWARN Bulletin
for access method; a file in the ACTIVE directory named AAREADME.DOC, outlines the contents.)
It can also be accessed via the WWW at:
This URL also enables executing several codes related to the orbits
of many geocentric science payload spacecraft. The codes related to
the heliospheric spacecraft trjectories can be executed through:
