Development of High -Data -Rate Burst Modem for WINDS

[Abstract] The Wideband Internetworking Engineering Test and Demonstration Satellite (WINDS) is an engineering test satellite for research and development of technology for future satellite communication networks. The National Institute of Information and Communication Technology (NICT) and the Japan Aerospace Exploration Agency (JAXA) are jointly developing the WINDS, and it is scheduled for launch in FY 2007. NICT has developed a high-data-rate burst modem for the WINDS network. The data rate of the modem is 622 Mbps. During the WINDS proto-flight test in October 2006, the modem’s BER was measured through the satellite transponder with a high-data-rate communication system of an earth station that consists of the modem and RF components. The measurement was conducted using the transponder in bent-pipe mode over six of its typical routes.
