SOTM—A Terminal Case
EM Solutions’ Ka-band SOTM terminal was extensively upgraded to work with Japan’s Kizuna (WINDS) Ka-band experimental satellite.

The Japanese National Institute of Information and Communications Technology (NICT) is the recipient of two, state-of-the-art Ka-band Satellite-On-The-Move (SOTM) terminals from communications engineering company EM Solutions. This delivery represents a key milestone for the firm for a partnership project with Tokyo-based Jepico Corporation.

EMSFig1 EM Solutions’ Ka-band SOTM terminal, originally built for the Australian Defence Force for use on the U.S. Wideband Global Satellite (WGS) military constellation, was extensively upgraded to work with Japan’s Kizuna (WINDS) Ka-band experimental satellite. The upgrade increases the terminal’s effective data rate up to 20Mbps, with a new 65cm diameter antenna dish and 40W radio transmitter.

Two initial SOTM terminals have been supplied to NICT for mounting on vehicles and a ship. They will be used as experimental equipment to enable a rapid response to emergencies and natural disasters.

The terminals maintain broadband data communications even from a moving vehicle or vessel and will establish a mobile communication ‘hub’ through the WINDS satellite to deliver high speed voice, data and video traffic from the affected site independent of the terrestrial network .

Founded in 1972, JEPICO is one of the best-known distributors and represents foreign suppliers of electronic components in the Defense, Aerospace, and Industrial markets in Japan, JEPICO provides a wide range of services including technical support, system integration, and engineering project services to Japanese clients that include the Government sectors. Headquartered in Tokyo, JEPICO has several offices in Japan, Taiwan and the USA. For more detail, please visit www.jepico.co.jp

Carrying out R&D and promotion for businesses within the ICT industry, the National Institute of Information and Communications Technology (NICT) drives economic growth and development as well as creates the promotion of R&D on network technologies, universal communications technologies, advanced ICT, and applied electromagnetic technologies. Such work helps the company to meet various challenges that range from daily living and global issues such as the declining birthrate and an aging population, to medical and educational issues as well as global warming. NICT also focuses on projects that produce advances through cross-disciplinary linkups of various technologies, especially in regard to ICT use in disasters.

EMSolutions_ad_MSM0413 KIZUNA (WINDS) was jointly developed by JAXA and NICT as part of the e-Japan Priority Policy Program of the Japanese government’s IT strategy headquarters. KIZUNA was launched by a H-IIA Launch Vehicle No.14 on February 23, 2008, from the Tanegashima Space Center to establish advanced information and telecommunications for Japan.

In addition to establishing a domestic ultra high speed Internet network, the project also aims to construct ultra high speed international Internet access, especially for Asian Pacific countries and regions that are closely related to Japan.

The KIZUNA project is responsible for the demonstration of the validity and usefulness of technologies related to large-capacity data communications in our space infrastructure project, “i-Space,” the purpose of which is to promote the use of satellites in such fields as Internet communications, education, medicine, disaster measures and Intelligent Transport Systems.
