USA 111 is an American military spacecraft. Initial orbital parameters were period 461 min, apogee 26,508 km, perigee 290 km, and inclination 27.0 deg.
Cosmos 2312, a Russian military communications spacecraft, was launched by a Molniya-M booster from Plesetsk cosmodrome at 20:10 UT. Initial orbital parameters were period 708 min, apogee 39,275 km, perigee 602 km, and inclination 62.9 km

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. To see a list select here.
  2. Global Positioning System satellites useful for navigational purposes and geodetic studies. To see a list select here.

    The GPS 2-NN series orbit in six distinct planes that are about 60 deg apart. Each plane has four "slots." Following are the 2-NN members in the planes/ slots. The RAAN decreases by about 1.0 deg each month; below are their 24 May, 95 RAAN longitudes.

  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.)

    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 (REQUEST@NSSDCA.GSFC.NASA.GOV). 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.)
