AMC-9 (AMERICOM 9 or GE 12) is a commercial communications satellite owned by SES Global .
Structure and purpose
The three-axis stabilized satellite with 24 Ku-band - and 24 C-band - transponders equipped and should provide 83 ° West of USA and Mexico with television and telecommunication services from the position. For the transmission electronics in the C-band semiconductor power amplifier (solid state power amplifiers, SSPAs) were used with a power of 20 watts, for Ku-band radiations traveling wave tube amplifier (traveling-wave tube amplifiers, TWTAs) with a power of 110 watts. It was built on the basis of the Alcatel Space Spacebus 3000B3 satellite bus and had a planned service life of 15 years.
AMC-9 was on June 7, 2003, a Proton-K / Briz-M carrier rocket from the rocket launch site Baikonur into a geostationary brought orbit.
Average
On the morning of June 17, 2017, an anomaly on board the satellite was detected in the form of a communication breakdown and a sudden change in orbit. Neither is telemetry received from the satellite more, nor can it be controlled. Its orbit in geostationary orbit, on which it drifts about 0.16 ° westwards per day, is stable and predictable.
On June 29th, two objects believed to be fragments were located near the satellite. SES was able to contact AMC-9 again on July 1st and switch off the transponders in order to avoid interference with other satellites.
The loss to SES from the interference with the satellite is estimated at $ 38 million.
