On February 15, 2011, the Ministry of Internal Affairs and Communications (MIC) received a report from the Information and Communications Council (Chairman: Takuma Otoshi, Chairman of IBM Japan) in response to Information and Communications Council Inquiry No. 2025 (July 29, 2008), concerning the “Technical Requirements for Ku-Band Helicopter Satellite Communications System.”
1. Background
In times of disaster it is vital that the state of the disaster scene is ascertained in detail so as to respond with quick and smooth rescue work and restorative countermeasures, and the use of highly maneuverable helicopters for information gathering from the sky proves to be most effective in such situations.
The system used at present transmits images from helicopters via relays with terrestrial radio stations, which limits the range of application to within the visible ranges of radio stations. Because of this, there is an increasing need for a helicopter satellite system (Heli-Sat) that uses communication satellites to provide excellent disaster resistance for the whole of Japan by transmitting images in real-time, even from areas that are not supported by terrestrial radio stations.
Against this background, the Information and Communications Council Technology Subcommittee, Satellite Communications System Subcommittee (Chief Investigator: Takeshi Hattori, Professor at Sophia University Department of Information and Communication Sciences) has been deliberating over the “Technical Requirements for Ku-Band Helicopter Satellite Communications System,” and a report was received on February 15, 2011.
2. Report
An outline of the Council's report is as per the attached document.
3. Schedule
The Ministry of Internal Affairs and Communications (MIC) will service the related regulations based on this reply.
