Eutelsat 115 West B

Eutelsat 115 West B (previously SATMEX 7) is a communications satellite that is operated by Eutelsat, providing video, data, government, and mobile services for the Americas. The satellite was designed and manufactured by Boeing Space Systems, and is a Boeing 702SP model communication satellite. It is located at 115 degrees west longitude. It was launched on board a SpaceX Falcon 9 rocket on 2 March 2015 (UTC time).

The satellite is solely propelled by electrically powered spacecraft propulsion, with the onboard thrusters used for both geostationary orbit insertion and station keeping.

The satellite had a launch mass of 4,861 pounds (2,205 kg).[3] It is notable for being the first[4] commercial communications satellite in orbit to use electric propulsion, providing a significant weight savings. Eutelsat 115 West B was launched with another Boeing 702SP satellite, ABS-3A, on the same rocket.

Eutelsat 115 West B is planned to be the first in a family of four satellites in the Eutelsat constellation. The satellite was scheduled for entry into service in November 2015, but entered service a month earlier than expected, in October 2015.[5][6]
