Boeing 702

Boeing 702

Boeing 702 is a communications satellite design. The Boeing Satellite Development Center tailors the payload of each Boeing 702 to meet customer specifications based on a modular design but with usually more than seventy transponders.

The baseline Boeing 702 is compatible with several orbital launch systems, including Delta IV, Atlas V, Ariane 5, Proton, and Sea Launch.

XIPS

Boeing offers a xenon ion propulsion system (XIPS) option for the 702. XIPS is 10 times more efficient than conventional liquid fuel systems. On a 702 equipped with XIPS, four 25-cm thrusters needing only 5 kg of fuel per year provide stationkeeping. Boeing asserts this is "a fraction of what bipropellant or arcjet systems consume". Boeing further asserts using XIPS can be used for final orbit insertion, conserving even more mass as compared to using an on-board liquid apogee engine.
