Galaxy 11 is an American geostationary communications satellite which is operated by Intelsat. It is located in geostationary orbit at a longitude of 32.8 degrees east, where it serves as a backup to the Intelsat 802 spacecraft. It was originally operated at 99° West and later spent most of its operational life at 91° West, from where it was used to provide communications services to Brazil and North America.[2]
Galaxy 11 was built for
As the first HS-702 to fly, the Galaxy 11 was one of the six which were launched before a design flaw in the type's solar arrays was discovered.
The launch of Galaxy 11 was conducted by
It currently operates at 44.9° East.
On 10 September 2022, the International Scientific Optical Network coordinated by the Keldysh Institute of Applied Mathematics reported that Galaxy 11 had been partially destroyed in geostationary orbit, which is potentially dangerous for other satellites.[8][9]
Despite the report from the Keldysh Institute of Applied Mathematics, the Galaxy 11 satellite continues to operate nominally with no disruption to communications service.
