Intelsat 901 is a television satellite of Intelsat . It was launched on June 9, 2001 with an Ariane 4 European launcher .
The satellite was designed for a minimum service life of 13 years. Since his fuel supplies were running low, he was provided with the Mission Extension Vehicle MEV-1 as an additional drive on February 25, 2020 . This should enable use until at least 2025.
Mission extension
The MEV-1 propulsion satellite was launched on October 9, 2019 with a Proton rocket from the Baikonur Cosmodrome . As a precaution, Intelsat 901 was moved to a cemetery orbit for the coupling of the MEV. After the MEV had also (approximately) reached this orbit in February 2020, several coupling approaches took place as a test.
Docking was achieved by penetrating a MEV-1 gripping mechanism into the nozzle and combustion chamber of the Intelsat 901 engine. The mechanism was expanded in the engine and then retracted again to create a rigid connection between the two satellites. It was the first coupling maneuver between two commercial satellites.
Intelsat 901, now equipped with MEV-1 as a new drive, is to replace Intelsat 907 . The launch of an MEV-2 for a corresponding use on another Intelsat satellite has already been ordered.
reception
Programs broadcast by Intelsat 901 could be received in Europe , the Middle East , Africa , South America and parts of North America until 2019/2020 .
The transmission takes place (e) in the C and Ku band .
