Galaxy IVR, Hughes 601HP or high power spacecraft, will provide broadcast and telecommunications service to North America, with the capability to provide back-up services to Latin America. Galaxy IVR features such innovations as dual-junction gallium arsenide solar cells, which have the ability to convert nearly 22% of the sun's rays into electrical power, and XIPS, a xenon ion propulsion system that is 10 times more efficient than the conventional bipropellant systems.
