JAXA Engineering Test Satellite ETS-VIII (Kiku 8) is the eighth technology test satellite in a series which started with ETS-1 in 1975 by NASDA. It was launched with the H-2A on December 18, 2006. ETS-VIII was developed by JAXA in cooperation with NICT and NTT. The aim of ETS-VIII is to enable satellite communications with small terminals. Unlike the Iridium satellites for mobile communication, ETS-VIII is positioned at GEO. However to fulfill the task the satellite must carry two very large antennas. So far, this has been the only use of the 204 configuration (four strap-on boosters) of the H-IIA launch vehicle.
- October 14, 2006 Launch of LDREX-2 with the Ariane 5, model antenna deployed.
- December 26, 2006 Both antennas were deployed.
- January 9, 2007 GEO orbit injection.
- May 9, 2007 The satellite switched to normal operation phase.
