Eutelsat 115 West B (previously SATMEX 7) is a communications satellite that is scheduled to be 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 will be 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 on board thrusters used for both geostationary orbit insertion and station keeping.
The satellite had a launch mass of 4,861 pounds (2,205 kg).[2] It is notable for being the first[3] 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 is scheduled for entry into service in November 2015.[4]

The launch occurred on March 2, 2015 at 03:50 UTC and the satellite has been deployed in the planned supersynchronous transfer orbit.[5][6]
The launch is also notable for being the first flight of Boeing's stacked satellite configuration for the Boeing 702SP,[7] a configuration Boeing designed specifically to take advantage of the SpaceX Falcon 9 v1.1 capabilities.[8]

But the Falcon 9 is not just changing the way launch-vehicle providers do business; its reach has gone further, prompting satellite makers and commercial fleet operators to retool business plans in response to the low-cost rocket. In March 2012, Boeing announced the start of a new line of all-electric telecommunications spacecraft, the 702SP, which are designed to launch in pairs on a Falcon 9 v1.1. Anchor customers Asia Broadcast Satellite (ABS) of Hong Kong and Mexico's SatMex plan to loft the first two of four such spacecraft on a Falcon 9 in December in a launch window that opens this year, though SatMex owner Eutelsat said last month that the launch has moved to early 2015. Using electric rather than chemical propulsion will mean the satellites take months, rather than weeks, to reach their final orbital destination. But because all-electric spacecraft are about 40% lighter than their conventional counterparts, the cost to launch them is considerably less than that for a chemically propelled satellite.
