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

3


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.

(1) Pilot ExperimentsIn order to firmly facilitate the in-orbit experiments of WINS, pilotexperiments such as data storage and transmission experiments, e-learningexperiments etc. using a commercial communication satellite have been conducted aiming at, - verification of the experiment environment, procedure - promotion of WINDS utilization

(2) Basic ExperimentsJAXA and NICT are making plans of basic experiments for the engineering evaluation of WINDS network system and newly developed technology.

(3) Application Experiments Ministry of Internal Affairs and Communications will make an announcement of opportunity for WINDS application experiments.JAXA and NICT will support the ministry to facilitate the experiments by providing technical support and communication capability of WINDS.
