Galaxy 10R is a US communications satellite launched on January 25, 2000 . He was with PanAmSat , one of the largest commercial satellite-based services companies, for three years . The satellite was the fifteenth in the line of Galaxy communications satellites .
Orbit data
The satellite was in geostationary orbit . This means that the circular orbit runs exactly over the equator and the orbital time corresponded exactly to the period of rotation of the earth around its own axis (1 sidereal day ). Thus this satellite appeared to be standing still when viewed from Earth.
The satellite
Galaxy 10R has a mass of 2137 kilograms. With the help of its solar sails, approximately 8800 watts of electrical power was generated to supply the 24 C-band and 24 Ku-band transponders with energy to enable image and sound transmission and digital communication in almost all of the approximately 11,000 cable networks in North America .
course
Galaxy 10R was on 25 January 20-00 at 1:12 AM UTC aboard a Ariane-4 - rocket on the Kourou Space Center in French Guiana started and placed in a geostationary orbit. It was flight number 126 of the Ariane 4 missile type.
After the primary XIPS drive system had failed a short time beforehand , the secondary system also failed on August 3, 2004. The manufacturer of the satellite determined that the system could no longer be repaired. The service life of the Galaxy 10R was shortened to three years and it was declared an unsuitable satellite. The insurance claim was met and therefore 75.3 million US dollars repaid. In June 2008, he was transferred to a cemetery orbit .
