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.

Solar concentrators, used to increase the amount of sunlight falling on the arrays, were fogging up due to vapours emitted by the satellite.

The launch of Galaxy 11 was conducted by Arianespace, using an Ariane 44L carrier rocket flying from ELA-2 at the Guiana Space Centre.

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.
