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.[1]
The baseline Boeing 702 is compatible with several orbital launch systems, including Delta IV, Atlas V, Ariane 5, Proton, and Sea Launch.
Boeing offers a Xenon Ion Propulsion System (XIPS) option for the 702 satellite system. [2] XIPS is 10 times more efficient than conventional liquid fuel systems. [3] On a XIPS equipped 702 satellite; four 25-cm thrusters provide economical station keeping, needing only 5 kg of fuel per year. [4] Boeing asserts that this is "a fraction of what bipropellant or arcjet systems consume". [5] Boeing further asserts, that a XIPS can be used for final orbit insertion. [6] This conserves even more payload mass, as compared to using an on-board liquid apogee engine. [7]
