Eutelsat 115 West B (formerly Satmex 7 ) is a geostationary communications satellite owned by the French satellite operator Eutelsat . The name of the satellite was changed in accordance with the numbering of Eutelsat, after the acquisition of the assets of the Mexican company Satmex . Designed to provide telecommunications services for the Americas .

The satellite does not use engines with chemical fuel, all orbital maneuvers and corrections will be carried out using an electric (ionic) propulsion system [1] .
It is located at the orbital position 114.9 ° west longitude [2] .
Launched on March 2, 2015, the Falcon 9 v1.1 launch vehicle along with the ABS-3A satellite.
The satellite reached the working orbit in early October and was put into operation on October 15, 2015, a month earlier than originally planned [3] [4] .
Apparatus
Built on the basis of the latest space platform Boeing 702SP by the American company Boeing . Power supply is provided by two wings of solar batteries and rechargeable batteries. The platform uses the XIPS all-electric propulsion system (Xenon Ion Propulsion System), the working fluid for which is xenon . All orbital corrections are carried out using this installation, without the use of chemical rocket fuel. The low fuel consumption of the propulsion system can significantly reduce the starting weight of the satellite, but the low thrust of the engines significantly increase the time it takes to enter the working orbit. The special design of the space platform allows you to launch two satellites simultaneously (one on top of the other) without additional fasteners. The expected life of the satellite is 15 years [5] . The launch mass of the satellite is 2205 kg [6] .
Transponders
The satellite has 34 active Ku-band transponders , switchable between three beams, and 12 active C-band transponders [2] [5] .
Coverage
Eutelsat 115 West B will provide a wide range of telecommunication services to consumers in the Americas [2] [5] .
Launch
Fifth launch of a commercial satellite into geo-transition orbit for SpaceX .
The launch of the Eutelsat 115 West B satellite took place at 03:50 UTC on March 2, 2015 with the Falcon 9 v1.1 launch vehicle from the SLC-40 launch complex at Cape Canaveral paired with a similar satellite ABS-3A . 35 minutes after launch, the satellite was launched into a supersynchronous geo-transitional orbit with indicators of 410 × 63 950 km, inclination 24.8 ° [7] [8] .
After the launch, it was announced that the satellites were launched on a better trajectory than expected, which would allow them to reach working orbits at least a month ahead of schedule [9] .
