B. Text of Launch Announcements.

1998-039A Cosmos 2359 is a Russian military reconnaissance spacecraft that was launched by a Soyuz-U rocket from Baikonur at 14:00 UT. The initial orbital parameters were period 89.2 min, apogee 300 km, perigee 192 km, and inclination 64.9 deg.
1998-038A Cosmos 2358 is a Russian military reconnaissance spacecraft that was launched by a Soyuz-U rocket from Plesetsk at 18:30 UT. Initial orbital parameters were period 89.5 min, apogee 334 km, perigee 167 km, and inclination 67.1 deg.
1998-037A INTELSAT 805 is the latest member of the INTELSAT fleet of geosynchronous satellites and was launched by an Atlas 2AS rocket from Cape Canaveral at 22:48 UT. It will provide voice, video, and internet services between Europe and the Americas after parking over at about 40-W longitude.
Cosmos 2357, Cosmos 2356, Cosmos 2355, Cosmos 2354, Cosmos 2353, and Cosmos 2352 are Russian military communications spacecraft that were launched by a Tsiklon-3 booster (an altered R-36M ICBM) from Plesetsk cosmodrome at 23:58 UT. These six belong to the Strela-3 series. They are reported to be fully functional even though the orbits deviated from circularity. The initial orbital parameters of all six were similar: period 118 min, apogee 1,870 km, perigee 1,300 km, and inclination 82.6 deg.
1998-035A THOR 3 is a Norwegian geosynchronous communications spacecraft that was launched by a Delta 2 rocket from Cape Canaveral. It carries 14 Ku-band transponders to provide voice and video communications to Europe after parking at 1.0-W longitude.
1998-034A STS 91 is an American Shuttle spacecraft that was launched from Cape Canaveral at 22:10 UT. The main mission was to dock with Mir station and deliver goods to Mir station. It carried also a 3.5 tonne, international Alpha Magnetic Spectrometer to measure very high energy cosmic rays, and some resources for microgravity experiments. It docked with Mir at 20:58 UT on 4 June 1998, undocked at 16:02 UT on 8 June 1998, and returned to Earth at 18:00 UT on 12 June 1998. Initial orbital parameters were period 91.1 min, apogee 330 km, perigee 326 km, and inclination 51.7 deg.

C. Spacecraft Particularly Suited for International Participation

Category I
  1. Spacecraft with essentially continuous radio beacons on frequencies less than 150 MHz, or higher frequencies if especially suited for ionospheric or geodetic studies.

    The last full list appeared as a part of SPX 520. The list will reappear only after major updates to the list are available.

  2. Global Positioning System satellites useful for navigational purposes and geodetic studies. ("NNN" denotes no national name. SPACEWARN would appreciate suggestions to update this list. An asterisk [*] denotes changes in this issue.)

    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)

         FTP:  [directory /igscb]

    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 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.

  3. Russian Global Navigational (Positioning) Spacecraft, GLONASS constellation. (SPACEWARN requests updates/additions from readers to this list. Entries marked "*" are updates or additions to the list.)

    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: maintained by the Coordinational Scientific Information Center (CSIC),Russian Space Forces.

  4. Actual decays/landings of payload spacecraft and rocket bodies (R/B) only. Additional information is not available.

  5. Miscellaneous Items. (This section contains information/data that are entered on occasion and may not be repeated in each issue of the SPACEWARN Bulletin.)

    Contact with the SOHO spacecraft (1995-065A) was lost soon after a planned maneuver on 24 June 1998. It has not been reestablished after a week of effort.

    At the request of NSSDC/WDC-A-R&S, the USSPACECOM has tracked IMP 8 (1973-078A) spacecraft and has provided two-line orbital elements. The last set of orbital elements have been of epoch 1981; the predictions from the 1981 set and the 1998 set are now being compared at the NSSDC.

    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 Office, Code 633, 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 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:

    Magnetospheric, Planetary, and Astronomical science data from many spacecraft may be accessed through links from the URL:
