1Introductione Wideband InterNetworking engineering test and Demonstration Satellite “KIZUNA” (WINDS) is an engi-neering test and demonstration satellite to establish high-speed satellite communication technology that was developed by the National Institute of Information and Communications Technology (NICT) and Japan Aerospace Exploration Agency (JAXA). It was launched on February 23, 2008, by an H-IIA rocket from Tanegashima Space Center of JAXA [1].Aer the initial checkout phase, the Regular operation phase (nominal phase) started and we have performed verication of the performance of the onboard instruments and fundamental transmission experiments according to the NICT “fundamental experiments” plan.Since April 2013, WINDS shied to the Post-operation phase and we have planned Fundamental experiments in the post-operation phases to be implemented.2WINDS experimentsWINDS was launched on February 23, 2008, and shied to the Regular operation phase since July 2008, aer being placed in geostationary orbit and having its health veried through the initial checkout. e timeline FiF1　Progress of operation and experiments of WINDSC/O : Check outAAEW : Association for Application Experiments of WINDS2017WINDSNICT200820092010201120122013JAXAAAEW201420152016▲LaunchC/ORegular operation phasePost-operation phaseFundamentalexperimentsFundamentalexperiments in post-operation phaseFundamental experimentsUtilization demonstrationexperimentsApplication experiments3 Ultra-High-Speed Satellite Communication Technology3-1 WINDS Fundamental Experiments of NICT in Post-Operation PhaseTakashi TAKAHASHI, Kazuyoshi KAWASAKI, Byeong-pyo JEONG, Norihiko KATAYAMA, Tomoshige KAN, and Mitsugu OHKAWAWideband InterNetworking engineering test and Demonstration Satellite (WINDS) was developed for establish the technologies of high data rate satellite communications and launched on February 23, 2008. After the initial check out on the geostationary orbit, NICT and JAXA, which are the organization developed WINDS, started their fundamental experiments. The application experiments, which were advatised by the Ministry of Internal Affairs and Communications, started from October, 2008.WINDS was moved to the second stage operation from March 2013 and NICT planed the later phase fundamental experiments and carried out.In this paper, the later phase fundamental experiments of NICT are described. 713 Ultra-High-Speed Satellite Communication Technology
