|2004-020A||Cosmos 2407 is a Russian military satellite that was launched by a Tsyklon 2 rocket from Baikonur at 06:00 UT on 28 May 2004. The initial orbital parameters were period 92.8 min, apogee 416 km, perigee 405 km, and inclination 65°.|
|2004-019A||Progress-M 49 is a Russian cargo carrier that was launched by a Soyuz-FG rocket from Baikonur at 12:34 UT on 25 May 2004. It carried 2.5 tonnes of supplies, water, food and fuel to the International Space Station (ISS). It docked automatically with the Zvezda module of the ISS at 13:55 UT on 27 May 2004. In preparation for the docking, the previously docked Progress M1-11 was evacuated on 24 May, carrying all the trash from the ISS, and was destined for a controlled burn on 3 June. The initial orbital parameters were period 89.3 min, apogee 246 km, perigee 236 km, and inclination 51.6°.|
|2004-018A||Rocsat 2 is a Taiwanese (ROC) remote sensing satellite that was launched from Vandenberg AFB by a Taurus XL rocket at 17:47 UT on 19 May 2004. The 750 kg satellite carries imaging instruments to take pictures of crop yields in Taiwan, natural disasters, and oil spills on land and ocean, and to image high altitude red lightning strokes called sprites. Initial orbital parameters were period 100.1 min, apogee 767 km, perigee 764 km, and inclination 99.1°.|
|2004-017A||AMC 11, also known as GE 11, is an American geostationary communications satellite that was launched by an Atlas 2AS rocket from Cape Canaveral at 22:22 UT on 19 May 2004. The 1.8 tonne satellite will enable dozens of television networks in America to provide HD videos through its 23 C-band transponders after parking over 131° W longitude.|
|2004-016A||DirecTV 7S is an American geostationary communications satellite that was launched by a Zenit 3SL rocket from the floating platform, Odyssey moored at 154° W in the equatorial Pacific ocean. The 13 kW satellite will provide direct-to-home television service to American homes through its 54 transponders and 27 spot-beams or, in another mode, through its 44 transponders and 30 spot-beams after parking over 119° W longitude. It is the second spot-beam satellite in the DirecTV fleet, after DirecTV 4S that was launched in November 2001.|

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 53, 2003-058A.
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.
