|1998-064B||PANSAT is an American communications spacecraft that was released from STS 95 at 17:20 UT. It will serve to train students at the Naval Postgraduate School. Initial orbital parameters were close to those of STS 95.|
|1998-064A||STS 95 is an American Shuttle spacecraft that was launched from Cape Canaveral at 07:19 UT. It carried resources for 80 microgravity experiments, a mini-communications spacecraft named PANSAT that was released on 30 October 1998 at 17:20 UT, the SPARTAN 201 solar observatory for deployment/recapture (on 1 November/3 November), and seven astronauts. One astronaut is a 77-year-old U.S. Senator (and the first American to orbit, 36 years ago) who will enable the first set of data on microgravity's effect on the aging process; he wrote "Hopefully, the data will help NASA's medical experts and others to develop insights and set new directions in search to alleviate medical problems that plague astronauts in space as well as the elderly on Earth. Once scientists have had a chance to analyze the data, I'm confident we'll find new avenues of promising research for combating some of the frailties of old age." (Parade magazine, 25 October 1998). Initial orbital parameters were period 95.8 min, apogee 561 km, perigee 551 km, and inclination 28.5 deg.|
|1998-063B||GE 5 is an American geosynchronous communications spacecraft that was launched to provide voice and video communications to North America. It was launched by an Ariane 44L rocket from Kourou at 22:16 UT.|
|1998-063A||AFRISTAR is a digital radio communications geosynchronous spacecraft that was launched by an Ariane 44L rocket from Kourou at 22:16 UT. It will enable radio communications to North African countries.|
|1998-062A||Progress M-40 is a Russian automatic cargo ship that was launched by a Soyuz-U rocket from Baykonur at 04:15 UT to carry cargo to the Mir station. It carried 7,285 kg of cargo including 400 kg of fuel, 2,500 kg of food, water, and scientific/engineering equipment required for the experiment (Znamia 2.5) to reflect Sun light toward Earth. It docked with Mir on 27 October. It may be the last flight of the Progress series since MIR may be deorbited into the Pacific in mid-1999. Initial orbital parameters were period 89.7 min, apogee 281 km, perigee 235 km, and inclination 51.7 deg.|
|1998-061B||SEDSAT 1 (Students for the Exploration and Development of Space) is an American mini-spacecraft that was launched by a Delta 2 rocket from Cape Canaveral. It will obtain images of the Earth and distribute them through the Web from the University of Alabama. It will also serve as a relay for amateur radio communications. Initial orbital parameters were period 101 min, apogee 1,079 km, perigee 547 km, inclination 31.4 deg.|
|1998-061A||Deep Space 1 is an experimental American spacecraft that was sent into deep space by an ion-propulsion engine after being launched by a Delta 2 rocket from Cape Canaveral. The drum-shaped 486 kg probe , which carries 80 kg of ionizable Xenon gas, is aimed to rendezvous with the asteroid 1992-KD in September 1999, and then move on to one or more cometary encounters. Ion propulsion engines require a smaller fuel mass though providing smaller acceleration compared to chemical fuels.|
|1998-060A||SCD 2 is a Brazilian (ground) environmental data relaying mini- spacecraft that was launched by a Pegasus rocket from Cape Canaveral at 00:30 UT. Initial orbital parameters were period 99.9 min, apogee 769 km, perigee 743 km, and inclination 25.0 deg.|
|1998-059A||MAQSAT 3 is a dummy payload to test the performance of the latest model of the Ariane series, Ariane 5. The rocket released an atmospheric re-entry demonstrator (ARD) also. Initial orbital parameters of MAQSAT 3 were period 666 min, apogee 36,612 km, perigee 1,152 km, and inclination 7.0 deg.|
|1998-058A||UHF F/O F9 is an American geosynchronous military communications spacecraft that was launched by an Atlas 2A rocket from Cape Canaveral Air Station.|
|1998-057A||Hot Bird 5 is a Eutelsat consortium's geosynchronous direct- broadcast communications spacecraft that was launched by an Atlas 2A rocket from Cape Canaveral. It will provide voice and video communications to Europe through 22 Ku-band transponders after parking over 13 deg-E longitude.|
|1998-056B||SIRIUS 3 is a Swedish geosynchronous communications spacecraft that was launched by an Ariane 44L rocket from Kourou at 22:51 UT. The 1,500 kg spacecraft will provide voice and video communications to Northern Europe and Scandinavia through 15 Ku-band 44 watt transponders after parking at about 5 deg-E longitude.|
|1998-056A||EUTELSAT W2 is a geosynchronous communications spacecraft of that consortium that was launched by an Ariane 44L rocket from Kourou at 22:51 UT. The 2,900 kg spacecraft will provide direct-to-home voice and video communications to North Africa, the Middle East, and Europe through its 24 (Ku-band?) transponders after parking over 16 deg-E longitude.|
|1998-055A||USA 140 is an American military spacecraft that was launched from Vandenberg AFB by a Taurus rocket.|

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.
