Boeing 702MP Satellite

Description and Purpose:
Boeing introduced the 702MP spacecraft in 2009 to meet the needs of customers seeking satellites in the middle-level power ranges. Its flexible design supports payloads that range in power from six to 12 kilowatts. The 702MP provides the high-capability features inherent in the flight-proven Boeing 702HP satellite model, but with a substantially updated satellite bus structure and simplified propulsion system.

Washington, D.C.-based Intelsat Ltd., the leading provider of fixed satellite services worldwide, became Boeing's first customer for the Boeing 702MP model spacecraft when it ordered four spacecraft in July 2009. In May 2013, Intelsat ordered an additional four and in July 2014 ordered a ninth.

General Characteristics:
The 702MP's modular assembly allows for efficient integration and test. The platform is able to accommodate hosted payloads (such as sensors, UHF and Ka-band for the U.S. government) for additional flexibility in customer business planning.

The Boeing 702MP is designed to provide 15 or more years of satellite service.

The modular "plug and play" antenna design allows significant flexibility in configuration definition to meet customer needs.

The payload is powered by a solar array consisting of ultra triple-junction gallium arsenide solar cells. This 702 solar array design has demonstrated exceptional reliability and performance on orbit.

The spacecraft is controlled by a powerful hybrid bi-propellant propulsion system that allows for payload mass growth with the addition of electrically augmented thrusters.

The Boeing 702MP is compatible with the Atlas, Ariane, Proton and Sea Launch launch vehicles.
