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 SPACEWARN Bulletin No. 545. The list will not be repeated in future issues until significantly revised.
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:
It provides many links to GPS related databases.
The latest addition to the fleet is Navstar 59, 2006-052A.
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.
According to CSIC the latest additions to the fleet are 2006-062A, 2006-062B, and 2006-062C.

This section contains information or data that are entered on occasion and may not be repeated in each issue of the SPACEWARN Bulletin.
The launch on 20 March from the Marshall Islands by a private company, SpaceX, with financial support from NASA, to test its automatic cargo delivery craft failed. Falcon 1 was to be one of the candidates for supplying cargo to the International Space Station (ISS). When it reached an altitude of about 300 km during the second stage burn, the control system failed, plunging the rocket into the Pacific Ocean.
SPACEWARN Bulletin 640 had assigned the names THEMIS 1 through 5 for what the USSTRATCOM had listed as Object A through E (2007-004A through 2007-004E). USSTRATCOM subsequently assigned the names as THEMIS A through E, rather than what the THEMIS mission had named THEMIS 1 through 5.
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 690.1,
NASA GSFC, Greenbelt, Maryland 20771, U.S.A., for specific information
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 obtained from:
Other files of interest for Earth-centered spacecraft can be generated via the URL,
