Abstract	The Japan Aerospace Exploration Agency (JAXA) and the National Institute of Information and Communications Technology have developed “WINDS,” a communications satellite that enables super-high-speed data communications, in an effort to research and develop advanced information networks based on the Japanese government IT strategy “e-Japan Priority Policy Program [1]–[3]”. An H-IIA rocket carrying WINDS was launched on Feb.23, 2008, at Tanegashima Space Center of JAXA. NICT developed the high-speed network with 622/1,244 Mbit/s using a bent-pipe relay line. The three earth terminals, Large Earth Terminal (LET) at NICT Kashima Space Technology Center and the two Super-high Data Rate Very Small Aperture Terminals (SDR-VSAT), were developed to construct a high-speed network with 622/1,244 Mbit/s. Also, a high-speed burst modem with high-performance FEC using turbo product code (TPC: (128, 120)) for a 622/1,244 Mbit/s dual rate high-speed network terminal was developed. After the launch of WINDS, NICT performed transmission experiments with the 622/1,244 Mbit/s dual rate high-speed burst modem at 622/1,244 Mbit/s, and measured the BER characteristic and the UDP/TCP packet error rate. We also confirmed that the network operates normally as a TDMA satellite communication system in the 622 Mbit/s mode between the three terminals. We also succeeded in transmission experiments with 3D, 4K HDTV using this system. This paper reports the configuration and performance of a 622/1,244 Mbit/s TDMA satellite communication system and the results of 622/1,244 Mbit/s TDMA satellite communication experiments using a highspeed burst modem.
