WINDS was established based upon “e-Japan program” of Japanese government in order to contribute a digital-divide free comfortable communication society by complementary utilization of ground based and satellite based communication network which has the following advantage: Wide Coverage, Broader Accessibility and Survivability against natural disaster
JAXA has been developing WINDS collaborating with National Institute of Information and Communication Technology (NICT).
JAXA: Total Network System Satellite System, Multi-Beam Antenna, Multi-Port Amplifier, Active Phased Array Antenna Ground System: Network Management Center, Regenerative Ground Terminals (USAT, HDR-VSAT) Satellite Tracking and Control SystemNICT: Onboard ATM Baseband Switching Router Bent-pipe Ground Terminals (LET, SDR-VSAT)
Objectives of WINDS program

Japan AerospaceExploration Agency
1. Establishment of ultra-high-speed fixed satellite communications technologies High-Speed communication rate
Realization of ultra-high-data rate communication.• 155 Mbps for home use (small terminal with 0.45m diam.
class antenna ) • 1.2Gbps for business use (large station with 5m diam. class
antenna ) Wide coverage
Ultra-high-data rate communication in a wide area of Asia /Pacific region
Establishment of total system for high-speed satellite based communication network which realizes “flexible” user assignment.
2. Verification of ultra-high-data rate satellite based communications network Verification of management of the ultra-high-data rate satellite based communication network and promotion of experiments.
