MEV 1 [Orbital ATK]

Orbital ATK will manufacture, test and launch the first Commercial Servicing Vehicle (CSV), the MEV-1 (Mission Extension Vehicle-1), which incorporates flight-proven technologies the company has used in its commercial satellite and space logistics businesses. After successfully completing a series of in-orbit tests, the MEV-1 will begin its mission extension service for Intelsat in 2019.

Orbital ATK will introduce in-orbit satellite servicing with the Mission Extension Vehicle-1 which is based on the company’s GEOStar spacecraft bus platform. Controlled by the company’s satellite operations team, the MEV-1 uses a reliable, low-risk docking system that attaches to existing features on a customer’s satellite. The MEV-1 provides life-extending services by taking over the propulsion and attitude control functions. The vehicle has a 15-year design life with the ability to perform numerous dockings and undockings during its life span.

The launch of the first MEV is slated for late 2018 as a co-passenger on a Proton-M Briz-M (Ph.4) rocket with in-orbit testing and demonstration to be performed with an Intelsat satellite. This testing is scheduled for completion by early 2019. MEV-1 will then relocate to the Intelsat satellite scheduled for the mission extension service, which is planned for a five-year period. Intelsat will also have the option to service multiple satellites using the same MEV.
