COSPAR/WWAS USSPACECOM SPACECRAFT LAUNCH INT.ID CAT. # NAME DATE (2001) -------------------------------------------------------- 2001-052A (26985) DirecTV-4S 27 November 2001-051A (26983) Progress M1-7 26 November
|2001-052A||DirecTV-4S is an American geosynchronous communications spacecraft that was launched by an Ariane 44LP rocket from Kourou at 00:35 on 27 November 2001. The 4.3 tonne satellite will provide more than 300 local TV channels to 41 metropolitan communities through its 11 C-band transponders after parking over 101° W longitude.|
|2001-051A||Progress M1-7 is a Russian automatic cargo carrier that was launched by an upgraded Soyuz-FG booster from Baikonur at 18:24 UT on 26 November 2001. It docked with the Zarya module of the International Space Station (ISS) at 19:45 UT on 28 November 2001 to deliver 2.5 tonne of food, fuel and equipment. Its docking remained to be secured by a spacewalk by one or more astronauts, so as to ensure a safe docking by a to-be-launched Shuttle. It carried also a microsatellite named Klibri to be released after the Progress undocked from Zarya. Initial orbital parameters were period 89.2 min, apogee 244 km, perigee 230 km, and inclination 51.6 .|

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.
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.
