SERVIS

Verifies the performance of parts and equipment supplied by the private sector in space by applying to actual spacecraft for low-cost, short-cycle, high-quality (CFB) satellites.
The development of SERVIS 1 and 2 will result in a low-cost commercial bus.

Space Environmental Reliability Verification Integrated System (SERVIS) Mission: Verify civilian parts and equipment in space for low-cost, short-cycle, high-quality (CFB) satellites. The development of SERVIS 1 and 2 will result in a low-cost commercial bus.

ETS-VIII

ETS-VIII is a geostationary satellite bus mounted with two of the world's largest antennas (19mx17m), developed primarily to establish and verify technologies such as higher-traffic processing, mobile telecommunications, and high-accuracy satellite positioning, all of which are essential for space missions at the beginning of the 21st century.

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.

USERS

USERS is an on-orbit experimental spacecraft system developed by USEF under a contract with Ministry of Economy, Trade and Industry (METI) and New Energy and Industrial Technology Development Organization (NEDO). It not only allows for long-term orbital experiments on a wide variety of challenges including the production of superconducting materials in the well-established environment, but also is capable of autonomously landing back on Earth.

UERS is a space experiment system developed by the Institute for Unmanned Space Experiment Free Flyer (USEF), under contract by the Japanese Ministry of Economy, Trade and Industry and the New Energy Development Organization (NEDO).

Missions:

  • Experimental manufacture of high-temperature superconductive materials
  • Verify technologies and components developed for terrestrial equipment in space applications
  • Establish autonomous recovery system
