InfoBalloon is the name of the captive balloon system which has been developed at Hokkaido University for collecting and distributing disaster information. InfoBalloon is intended for operations both in disaster time and ordinary time. Therefore, InfoBalloon should provide information services to residents in its territory community with long-term and stable operations. In this report requirements of captive balloons for realizing continuous services are firstly introduced and then technical problems to be addressed are discussed. To enable long-term and stable operations of InfoBalloon, a new balloon shape and tethering method for InfoBalloon have been developed. The balloon shape for the wind effect and the tethering method with three parallel wires and a pivot base keep InfoBalloon at required position in air against a wind with stable attitude. A breakage prevention system against heavy wind and thunder is also designed and now being implemented for safety and continuous operations of InfoBalloon.
