Executive Comment (in English)
"Innovation in Telecommunications ] The Perspective of a Satcom Terminal Developer"
Dr. Rowan Gilmore
Managing Director, EM Solutions,
Brisbane Australia
"An often overlooked requirement is that innovation also requires great (or even heroic) customers - customers who seek the rewards of innovation but still have the risk appetite to be able to fund and trial innovations that might run late, be over budget, or that do not fully meet specification!"
In AIAA ICSSC-2015, which was held in Gold Coast of Australia from September 7 to 10, 2015, Dr. Rowan Gilmore has worked hard and well as the General Chair. He makes an excellent comment about innovation in telecommunications.

Space Japan Book Review (in English)
Michael M. Lewis:"Flash Boys; A Wall Street Revolt", Writers House, 2014.
Dr. Takashi Iida, Editorial Advisor of Space Japan Review
The round-trip propagation time of radio wave is about 0.3 seconds in the satellite communication using a geostationary satellite positioned at 36,000km altitude above the equator. So the satellite communication can not compete at all to discussion in this book that treats milliseconds (mS) and/or microseconds (ƒÊS). Moreover, the satellite communications related person might feel far away this book increasingly, because it became a reputation in the market of stock trading. I, the reviewer of this book, am interested in this book precisely because the satellite communication can not compete at all. When I read it, even communication technology engineer, who has a technology goal to convey the information as quickly as possible, is awaked to that decreasing the propagation time produces much important and highly profitable worth rather than a market issue of stock trading. It is interesting that some of such examples have been described in this book. This review is based on Japanese translation version of this book...
