Outline The ETS-VIII's missions are to develop technologies, and test and verify them in space. The targeted technologies include mobile-satellite communications, mobile-satellite digital multimedia, and basic technologies for building satellite positioning systems, through large-scale geosynchronous satellite bus technologies for 3-ton class satellites -- the world's largest class in the early 2000s. The ETS-VIII also targets such large-scale deployable antenna technologies as 13 meter-class deployable antennas, and high-accuracy time standard systems and other positioning equipment.
