| 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 http://nasa.asu.edu/asusat/. 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 http://ssdl.stanford.edu/opal/home.html 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". (http://cast.weber.edu/jawsat/jawsat.html) 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. |
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. |

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.
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: http://www.rssi.ru/SFCSIC/english.html maintained by the Coordinational Scientific Information Center (CSIC),Russian Space Forces.
