Also, we measured propagation characteristics with this earth terminal while moving. e results are introduced in 3-11 of this report.3.3Function verification experiment of small station on vesselWe mounted the antenna used for the Small-sized ve-hicle station and veried its function and performance such as the tracking property and basic transmission character-istics by linking a vessel and land station via satellite.e earth station was installed on a research vessel in collaboration with the Japan Agency for Marine-Earth Science and Technology. We succeeded for the rst time in the world in the tele-operation of a remotely-operated vehicle connected with the research vessel from land via satellite [2].3.4Satellite network experimentis experiment has been performed since the funda-mental experiments during the Regular operation phase. We evaluate throughput of upper protocol (TCP/IP, etc.) of a satellite network of a star type or mesh type.3.5Satellite communication experiments for disaster countermeasuresWe could show the presence of satellite communication in the Great East Japan earthquake that occurred in March 2011, by oering temporary communication lines using WINDS.We will perform a verication experiment to oer various data such as video to grasp the situation of damage, data and voice necessary for rescue in a case where com-munication infrastructure is damaged widely due to a large-scale disaster by a comprehensive network linking a satellite communication network and ground network such as a wireless LAN network.e results are introduced in 3-3 of this report.3.6Connection experiment with ground networksSince the fundamental experiments during the Regular operation phase, we will verify comprehensive transmission properties such as video, voice, and data, etc. when a ground network such as JGN and a wireless network are linked to the WINDS network.We introduce an example of an experiment in 3-4 of this report in which we distributed high-quality video taken by a 3D 4K-HDTV camera by combining 622/1244 Mbps dual rate high-speed burst modem, a Time Division Multiple Access satellite communication network system and JGN.3.7Medical ICT satellite communication experimentis experiment has been performed since fundamental experiments during the nominal phase in collaboration with Yokohama National University.It is becoming more and more important to establish safe and secure medical security systems. e purpose of the experiment on a medical ICT network using satellite communication is to be of some help in establishing a more ecient healthcare system and remote medical education system by introducing satellite communication to a body area network (BAN) that collects various biomedical signals in real time and transmission of diagnostic images.3.8Basic experiments for future satellite technologye following eight kinds of experiment were planned as basic experiments for technology expected for future communication satellites such as next engineering test satellites.① Orthogonal frequency-division multiplexing (OFDM) transmission experimentA broadband transponder of 1.1 GHz is installed on WINDS. We have developed a high-speed satellite com-munication modem by multi-level modulation frequency multiplication that makes use of the property of this transponder. We veried high-speed transmission technol-ogy at 3.2 Gbps by orthogonal frequency-division multi-plexing that multiplies 16APSK (50 Mbps) code to 16 frequency multiplication.e result of this experiment is introduced in 3-5 of this report.② Experiment of reallocation of satellite communication line that can be reconstructedWe developed a channelizer that increases the e-ciency of frequency use in trac conditions in a disaster that change moment by moment. We veried that a satellite communication line is reallocated by changing the band-width and center frequency using a channelizer linked with the earth station by transmitting multiple data signals of 1 ~ 64 Mbps via WINDS [3].③ SHV transmission experimentWe verify technology necessary for next-generation satellite broadcasting in collaboration with NHK.We verify transmission characteristics at the date rate 733-1 WINDS Fundamental Experiments of NICT in Post-Operation Phase
