| 1999-045A | Cosmos 2366 is a Russian military spacecraft that was launched from Plesetsk at 12:30 UT by a Cosmos 3M rocket. Initial orbital parameters were period 104.8 min, apogee 1,007 km, perigee 964 km, and inclination 82.9 deg. |

| 1999-044A | Cosmos 2365 is a Russian military spacecraft that was launched from Plesetsk at 18:00 UT by a Soyuz-U rocket. Initial orbital parameters were period 90 min, apogee 368 km, perigee 176 km, and inclination 67 deg. |

Globalstar M024, M027, M053, and M054 are the latest to join the American fleet of communications satellites. They were launched by a Delta 2 rocket from Cape Canaveral at 16:37 UT. The fleet now totals 36 satellites and enables voice and data transmissions to/from stations located far away from cellular networks. Averaged initial orbital parameters were period 113.3 min, apogee 1386 km, perigee 1368 km, and inclination 52.0 deg. |
| 1999-042A | TELKOM 1 is an Indonesian geosynchronous communications spacecraft that was launched by an Ariane 44P rocket from Kourou at 22:52 UT. The 1.7 tonne, 4 kW spacecraft carries 24 C-band and 12 extended C-band transponders to provide voice and video communications to Indonesia and other regional countries after parking over 108 deg-E longitude. |

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/english.html maintained by the Coordinational Scientific Information Center (CSIC),Russian Space Forces.

The names of 1999-029A, 1999-029B, and 1999-029C that were launched by an Indian PSLV rocket were reported in SPX 547 as IRS-P4/OCEANSAT, KITSAT 3, and TUBSAT. However, USSPACECOM continues to list the names as KITSAT 3, TUBSAT, and OCEANSAT. We have contacted USSPACECOM and are awaiting their confirmation or correction. No response as of 31 August 1999.
The encounter phase of the Deep Space 1 (1998-061A) spacecraft with the kilometer-sized asteroid, Braille, was only a partial success. The camera was not oriented correctly to obtain images of the asteroid close up. However, the orbital parameters of the asteroid determined during the cruise phase has indicated that the asteroid will probably enter an Earth orbit and soon burn out in the atmosphere in a few thousand years.
The Saturn-bound Cassini (1997-061A) spacecraft made a near-Earth pass (1,171 km) on 18 August 1999, 03:28 UT, to gain an extra speed of 5.5 km/s on the way to reaching Jupiter (on 30 December 2000) so as to get an additional boost of several more km/s necessary to reach Saturn.
NSSDC/WDC-A-R&S is an archival center for science data from many spacecraft.
Many space physics datasets are on-line for electronic access through:
http://nssdc.gsfc.nasa.gov/space/
For off-line data, please contact the Request Office, NSSDC, Code 633, NASA GSFC, Greenbelt, Maryland 20771, U.S.A., for specific information (request@nssdca.gsfc.nasa.gov). 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.)
