Intelsat 907 (orIS-907[1]) was acommunications satellite operated byIntelsat.

Launch

[edit]

Intelsat 907 was launched by anAriane 4 rocket fromGuiana Space Centre, French Guiana, at 06:44 UTC on February 15, 2003.[6]

Capacity and coverage

[edit]

The 4.7 tonne spacecraft provided data-relay among installations in North America, South America, Western Europe and Africa through its array ofC band andKu bandtransponders after parking over 27.5 degrees west longitude. It replaced the agingIntelsat 605.[6]

Replacement

[edit]

On 2 April 2020, the Intelsat 907 was replaced by theIntelsat 901 satellite. Before this, Intelsat 901 had been taken out of operation (having operated for about 18 years in another orbital slot) and moved into graveyard orbit where it docked withMission Extension Vehicle-1 (MEV-1), a satellite service craft. MEV-1 then took responsibility of propulsion and attitude control of the satellite pair. The satellites then descended back to geostationary arc, where Intelsat 901 then replaced Intelsat 907's communications responsibilities. Intelsat 901 took over from Intelsat 907 on 2 April 2020. It is expected that the Intelsat 901 will operate for five more years, after which MEV-1 will again raise it to graveyard orbit for decommissioning.[4]
