|2003-061A||Double Star 1
(also known as Tan Ce 1, and TC 1) is a Sino-European
(CNSA-ESA) satellite that was launched by a Long March 2C/SM rocket
from Xichang Satellite Launch Center in the Sichuan province of
China (PRC) at 19:06 UT on 29 December 2003. The 330 kg, 260 W
satellite is cylindrical, with a diameter of 2.1 m, a height of
1.4 m, and spins at a rate of 15 rpm. It carries eight instruments
to probe Earth's magnetosphere, five from ESA and three from CNSA.
(The ESA instruments are legacies from ESA's Cluster mission.) The
data from all instruments will be stored on-board and dumped
over three ground stations: Shanghai and Beijing in China, and
Villafranca in Spain. The Program Manager is Bodo Gramkow (ESA) and
the Project Scientist is Philippe Escoubet (ESA). There will be
coordination between the Cluster and Double Star missions. For
more information, see
Initial orbital parameters were period 1,644 min,
apogee 78,970 km, perigee 562 km, and inclination 28.23°.
ASPOC (Active Space Potential Control) is to maintain the potential of the spacecraft at a low voltage. The tendency to attain high positive voltage due mainly to photoelectric emission is sought to be neutralized by shooting out positive indium ions. The spacecraft potential is continuously monitored by the PEACE instrument. The Principal Investigator is K. Torkar, IWF, Graz, Austria.
PEACE (Plasma Electron And Current Experiment) infers the positive potential of the spacecraft by counting the number and speed of the thermal electrons that impinge on it. This measurement is an input to the operation of ASPOC. The Principal Investigator is A. Fazakerley, MSSL, Dorking, UK.
FGM (Flux Gate Magnetometer) is located on a 3.5 meter long boom and measures the magnetic field along the orbit at a rate up to 67 samples per second. The Principal Investigator is Chris Carr, IC, UK.
HIA (Hot Ion Analyzer) measures the distribution function of ions in the magnetosphere and the solar wind, during each spin period of four seconds. The Principal Investigator is Henri Reme, CESR, Toulouse, France.
STAFF-DWP (Spatio-Temporal Analyzer of Field Fluctuations and Digital Wave Processor) The data from the magnetometer consists of two components. The low frequency components are transmitted to the ground for analysis. The higher frequency components are best analyzed on-board by a DWP and STAFF and the result telemetered to the ground stations. The Principal Investigators are N. Cornilleau-Wehrlin of CETP, Velizy, France; and H. Alleyne, Sheffield University, UK.
HEED (High Energy Electron Detector) measures the flux of energetic electrons in the magnetosphere. The Principal Investigators are W. Zhang and J. B. Cao of CSSAR, China. (CSSAR stands for Center for Space Science and Applied Research of the Chinese Academy of Sciences, Beijing)
HEPD (High Energy Proton Detector) detects energetic protons in the magnetosphere and solar wind. The Principal Investigators are J. Liang and J. B. Cao, CSSAR, China.
HID (Heavy Ion Detector) detects heavy ions of AMU>4. The Principal Investigators are Y. Zhai and J. B. Cao, CSSAR, China.

It wll be parked at 172°E longitude.|
|Cosmos 2402, Cosmos 2403, and Cosmos 2404 are the latest additions to the Russian fleet of Glonass navigational satellites.

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.
