|1998-068A||BONUM 1 is a Russian geosynchronous communications spacecraft that was launched by a Delta 2 rocket from Cape Canaveral at 23:54 UT. This first private sector spacecraft carries eight 75 W Ku-band transponders that enable 50 channels of direct-TV broadcasts to Russia and Eastern European countries after parking over 36 deg-E longitude. Gallium Arsenide solar cells provide a total power of 1.5 kW.|
|1998-067A||ISS-Zarya is a Russian-built first module of the International Space Station (ISS) that was launched by a Proton-K rocket from Baykonur at 06:40 UT. The ISS is also known by the Russian acronym, MKS standing for the transliterated Mezhdunarodnii Kosmicheskii Stantsii. It will require 43 rocket launches, including about 35 Shuttles, over at least a five year period to complete the 16-country, 60 m x 24 m x 21.5 m, 454 tonne, 110 kW, and >$50 billion ISS (or whatever its eventual name/acronym may turn out to be). Zarya ("Dawn") module has a mass of 27 tons and will contribute power, attitude control, fuel, and command/control coordination to the other 33 (USA 18, Russia 9, Japan 3, ESA 2, and Canada 1) modules. No definitive information is currently available regarding ISS's scientific, commercial, or military vision. It is likely that some or all of the science payload now housed in the 140-tonne Mir station may be transferred to the ISS in the event of having to dissemble and deorbit Mir; the orbital parameters of the two are similar. Initial orbital parameters of ISS-Zarya were period 92 min, apogee 396 km, perigee 384 km, and inclination 51.6 deg.|
|Iridiums 02, 86, 85, 84, 83 are communications spacecraft of the Iridium consortium that were launched by a Delta 2 rocket from Vandenberg AFB at 13:37 UT. The Iridium fleet enables voice and data communications from/to phones located far away from cellular networks. Initial orbital parameters of all these five were similar: period 95 min, apogee 536 km, perigee 517 km, and inclination 86 deg.|
|1998-065A||PANAMSAT 8 is an American geosynchronous communications spacecraft that was launched by a Proton-K rocket from Baykonur at 05:12 UT. It carries 24 C-band and 24 Ku-band transponders to provide television channels after parking over 166-E longitude.|
|1998-064C||Spartan 201-05 is an American solar observatory that was released and recaptured by the Shuttle STS 95. It made 43 hours of solar corona monitoring with its white light (WLC) and ultraviolet (UVCS) cameras. The images may be seen via the URL, http://thalia.gsfc.nasa.gov/~gibson/SPARTAN/spartan.html. The data will assist in the recalibration of the SOHO spacecraft instruments. SOHO was resurrected after some months of hibernation. The orbital parameters of Spartan were period 95.8 min, apogee 561 km, perigee 551 km, and inclination 28.5 deg. It was retrieved by STS 95 at 08:48 UT on 3 November 1998.|

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.
