|1999-010A||Raduga 104, also known as Globus 1, is a Russian geosynchronous military spacecraft that was launched by a Proton-K rocket from Baykonur at 04:00 UT. There are now a total of 33 Radugas in orbit of which only five are functional.|
|1999-009B||SKYNET 4E is a British geosynchronous military spacecraft that was launched by an Ariane 44L rocket from Kourou at 22:44 UT. The parking longitude of the 1.5 tonne spacecraft is not available.|
|1999-009A||Arabsat 3A is a geosynchronous communications spacecraft of that consortium that was launched by an Ariane 44L rocket from Kourou at 22:44 UT. The 2.7 tonne satellite will provide voice, video and digital communications to the Middle East, North Africa, and Southern Europe in 22 Ku-band channels after parking near 30 deg-E longitude.|
|1999-008C||Sunsat is a South African research/education satellite that was launched by a Delta 2 rocket from Vandenberg AFB at 10:29 UT. It will carry out remote sensing of the Earth and encourage high school student participation. Initial orbital parameters were period 100 min, apogee 857 km, perigee 644 km, and inclination 96.5 deg.|
|1999-008B||Oersted (Ørsted) is a Danish ionospheric science spacecraft that was launched by a Delta 2 rocket from Vandenberg AFB at 10:29 UT. The 62 kg spacecraft carries a fluxgate vector magnetometer, an Overhauser magnetometer (for field magnitude only), and particle detectors (for 0.03-1.0 MeV electrons, 0.2-30 keV protons, and 1-100 MeV Alpha particles). Initial orbital parameters were period 100 min, apogee 857 km, perigee 644 km, and inclination 96.5 deg. For further details, see http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1999-008B.|
|1999-008A||ARGOS (Advanced Research Global Observation Satellite) is an American military spacecraft that was launched by a Delta 2 rocket from Vandenberg AFB at 10:29 UT. The three tonne spacecraft may be a technology demonstration model, but enbles observation of baseline data on Earth's atmospheric constituents. Among the instruments onboard are an ultraviolet imager, X-ray detectors, and plume detectors. Initial orbital parameters were period 102 min, apogee 842 km, perigee 822 km, and inclination 98.7 deg.|
|1999-007A||Soyuz TM-29 is a Russian cosmonaut-transporting spacecraft that was launched by a Soyuz-U rocket from Baykonur to carry two cosmonauts to the Mir station. Initial orbital parameters were period 91.6 min, apogee 364 km, perigee 346 km, and inclination 51.7 deg.|
|1999-006A||JCSAT 6 is a Japanese geosynchronous communications spacecraft that was launched by an Atlas 2AS rocket from Cape Canaveral. It will provide voice and video communications to East Asia and Japan through its 31 Ku-band transponders after parking over 124 deg-E longitude.|
|1999-005A||Telstar 6 is an American geosynchronous communications spacecraft that was launched by a "Proton class" booster from Baykonur at 05:12 UT. The 3.8 tonne spacecraft carries 24 C-band and 28 Ku-band transponders to provide voice and video communications to the US and Canada, after parking over 93 deg-W longitude.|
|1999-004A, 1999-004B, 1999-004C, 1999-004D||Globalstar M36, M23, M38, and M40 are low altitude American communications spacecraft that were launched by a Soyuz-U booster from Baykonur, each with a mass of 450 kg. They are the first four of the planned 48-spacecraft (plus four reserves) fleet that will enable voice and data relays from/to telephones far away from cellular networks. The network becomes customer-ready after the 32 become operational. (Plans are for seven Delta 2 launches of 28 spacecraft.) Initial orbital parameters of all four were similar: period 103.5 min, apogee 952 km, perigee 911 km, and inclination 52 deg.|
|1999-003A||Stardust is an American interplanetary exploration spacecraft that was launched by a Delta 2 rocket from Cape Canaveral. The 350 kg spacecraft carries traps to collect cometary dust from Comet Wild 2, and "interstellar" dust and return them to Earth in a landing capsule in early 2006 for detailed chemical and isotopic analysis. The collector is an aerogel, an inert microphorous silica-based substance. One side of the collector will collect the cometary dust during the rendezvous in early 2004, while the other side will collect interstellar dust during October 1999-March 2000, and May 2002-October 2002. Stardust's rendezvous with the 4-km diameter comet will be at a distance of 150 km when the comet will be at 1.85 AU from Sun. Comet Wild 2 is a relatively fresh comet that was redirected by Jupiter to a low periapsis (1.583 AU) orbit during its September 1974 encounter.

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/glonass.html maintained by the Coordinational Scientific Information Center (CSIC),Russian Space Forces.
The latest additions to the GLONASS fleet are,
