B. Text of Launch Announcements.

2000-004E ASUSat (Arizona State University SATellite) is an American microsatellite that was released from JAWSAT. This student-engineered spacecraft carries components for engineering tests. For further information, see Initial parameters of the circular orbit were period 100.4 min, altitude 773 km, and inclination 100.2 deg.
2000-004D FALCONSAT is an American military microsatellite that was released from JAWSAT. It is reported to be a technology testing mission. Initial parameters of the circular orbit were period 100.4 min, altitude 773 km, and inclination 100.2 deg.
2000-004C OPAL (Orbiting Picosatellite Automated Launcher) is an American microsatellite for engineering tests of components, and was released from JAWSAT. In turn, it was also to deploy six student-engineered picosatellites as a feasibility test; see for a sketch of the mission. Initial parameters of the circular orbit were period 100.4 min, altitude 773 km, and inclination 100.2 deg.
2000-004B OCS (Optical Calibration Sphere) is an American military microsatellite that was released from JAWSAT. Initial parameters of the circular orbit were period 100.4 min, altitude 773 km, and inclination 100.2 deg.
2000-004A JAWSAT (Joint air force Academy-Weber state university SATellite) is an American military minisatellite that was launched from Vandenberg AFB by the first of 450 (350?) decommissioned/re-engineered Minuteman-2 rockets at 03:03 UT. After its own launch, JAWSAT deployed four microsatellites: FALCONSAT, OCS, OPAL, and ASUSat. No information is available on the instruments on board JAWSAT, except that according to one report it may carry a "High-Resolution Imaging System". ( Initial parameters of the circular orbit were period 100.4 min, altitude 773 km, and inclination 100.2 deg.
2000-003A Zhongxing 22 is a Chinese (PRC) geosynchronous communications spacecraft that was launched from Xichang Center in Sichuan province at 16:45 UT by a Long March 3A rocket. The 2,300 kg spacecraft will be parked over 98-E longitude.
2000-002A Galaxy 10R is an American geosynchronous communications spacecraft that was launched by an Ariane 4 rocket from Kourou at 01:12 UT. The 2,137 kg, 8.8 kW spacecraft carries 24 C-band and 24 Ku-band transponders to provide digital and video communications to nearly all of about 11,000 cable systems in North America after parking over 123-W longitude.
2000-001A USA 148, also known as DSCS 3 (Defence Satellite Communications System 3) is an American military geosynchronous communications spacecraft that was launched by an Atlas 2 rocket from Cape Canaveral at 01:03 UT. (Being the 10th in the DSCS 3 FN series, its full name is likely to be DSCS 3 F10.) With a solar power of 1,240 W, the jam-proof spacecraft has six "SHF" relaying channels in the frequency range of 50-85 MHz which can be received by an 84 cm dish. The craft is triaxially stabilized at about 0.1 deg in roll and pitch. Parking longitude is unavailable.

C. Spacecraft Particularly Suited for International Participation

  1. Spacecraft with essentially continuous radio beacons on frequencies less than 150 MHz, or higher frequencies if especially suited for ionospheric or geodetic studies. (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 SPX 545. The list will not be repeated in future issues until significantly revised again.

    Geoffrey E. Perry, MBE.
    We are sad to learn that Geoffrey Perry passed away on 18 January 2000. Mr. Perry has been almost the sole source of updates to this section since over a decade ago, during and prior to his affiliation with the Kettering Group in Cornwall, England. His firsthand knowledge of satellites carrying beacons of interest to ionospheric studies, especially the many in the Russian COSMOS series of this kind and others in the GLONASS fleet has been of immense help to the space physics community in general and the Spacewarn Bulletin in particular. Also notable was his alerts to us whenever (occasionally) NORAD's orbital elements of a satellite, or of a rocket body, or even of debris did not match its International ID. We searched the back issues of the Bulletin since it went on-line in 1991. There have been 19 instances of explicit acknowledgement of Mr. Perry's help to us and, presumably, as many in the Bulletins that were not stored electronically in the prior decade.

  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.

  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-545. 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. No further information is 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.)

  6. Related NSSDC resources.

    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 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 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.)
