|The names of these microsatellites are yet to be ascertained. However, they are likely to be from the following list: Demeter, Saudisat 2, Saudicomsat 1, Saudicomsat 2, Latinsat-C, Latinsat-D Unisat 3, and Amsat-Echo. Hopefully, the identification will be completed in a few weeks, in time for dissemination through the next Bulletin, SPX.609. They were launched by a Russian-Ukrainian Dnepr rocket from Baikonur at 06:00 UT on 29 June 2004.|
|2004-024A||Telstar 18 (APstar 5) is a Russian communications spacecraft that was launched by a Zenit 3SL rocket from the Odyssey platform floating on the equatorial Pacific Ocean at 04:00 UT on 29 June 2004. It was intended to be a geostationary satellite, but due to the premature stoppage of the boost from the final DM-SL stage, it ended far below the geostationary orbit. Efforts may be underway to use the trim-maneuver thruster attached to the satellite itself to slowly raise the orbit to an approximately geostationary status. (Fuel use from that thruster usually impacts adversely on the useful lifespan of a geostationary satellite.)|
|2004-023A||Navstar 55, also known as USA 178, and as GPS 2R-12, is an American navigational satellite in the GPS fleet that was launched from Cape Canaveral by a Delta 2 rocket at 22:54 UT on 23 June 2004. The 2.1 tonne satellite will soon be maneuvered into Slot 4 in Plane F to replace the aging GPS 2A-16 that was launched in November 1992. (GPS 2A-16 will, however, be repositioned in the same Plane as a backup, until its failure. Links to GPS fleet are available in section C-2 below. The initial orbital parameters were period 355.8 min, apogee 20,368 km, perigee 145 km, and inclination 39°.|
|2004-022A||Intelsat 10-02 is an geostationary communications spacecraft in the (recently privatized) American Intelsat fleet that was launched by a Proton-M rocket from Baikonur at 22:27 UT on 16 June 2004. The 3 tonne satellite will provide digital broadcasting, telephone, and broadband internet access to users in Europe, South America, Africa and the Middle East through its 36 Ku-band, and 70 C-band transponders after parking over 1° W longitude.|
|2004-021A||Cosmos 2406 is a Russian military satellite that was launched from Baikonur by a Zenit 2 rocket at 01:28 UT on 10 June 2004. We adopt tentatively, the name (Cosmos 2406) assigned by the USSPACECOM as well as by the Russian news agencies, Novosti and Interfax. Since there has already been a Cosmos 2406 (and Cosmos 2405, and Cosmos 2407), it may happen that the spacecraft may be renamed or that the names of the previous Cosmos NNNNs will be revised. If that happens, they will be reported in a future issue of the SPACEWARN Bulletin. The initial orbital parameters of 2004-021A are period 102.1 min, apogee 865 km, perigee 847 km, and inclination 71°.|
Note: The full list appeared in SPX 545. The list will not be repeated in future issues until significantly revised again.
High precision (<20 cm) GPS constellation tracking data obtained from the network of about 400 dedicated global stations that are of interest to geodetic study may be obtained through the following services provided by the International GNSS Service (IGS). The IGS is a service of the International Association of Geodesy (IAG).

The standard format of the GPS situation appeared in SPACEWARN Bulletin No. 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.
The latest addition to the fleet is Navstar 54, 2004-009A.
All GLONASS spacecraft are in the general Cosmos series. The Cosmos numbers 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 last appeared in SPACEWARN Bulletin No. 545. It will not be repeated in view of the excellent updated source at: http://www.glonass-ianc.rsa.ru/ maintained by the Information-Analytical Center (IAC), Russian Space Agency.
