Executive Comment (in English)
IT'S ALL ABOUT RELATIONSHIPS
Dr. Mark S. Maurice
AIAA, Vice President - International Air Force Office of Scientific Research
Director, International Office
"It's all about building relationships. If you build a good relationship, you automatically build international good will, strengthen partnerships, promote interoperability, avoid technological surprise, and perhaps most importantly, accelerate S&T achievement."
Interview with CEO (in English)
Mr. Mark Dankberg
Chairman and CEO
ViaSat, Inc., Carlsbad, CA
"We also think that one of the most important elements for satellite communications in the future is to better educate the public, and especially public policy makers, about the potential for satellite to provide high quality and high performance connectivity in the future." In our interview, ViaSat Inc. Chairman and CEO Mr. Mark Dankberg speaks passionately about his business strategies for worldwide satellite communications in Ka-band broadband applications.

Development and Operation of a Pico-Satellite Negaih
Seiji Kuroki, Soka University, JAPAN
A Soka University pico-satellite Negaihwas launched on May 21st, 2010 at Tanegashima Space Center, Japan to decay on June 26th, 2010. The satellite is a CubeSat that measures just ten centimeters cubic and weighs a mere kilogram. Its orbit is 300km altitude with 30 degree inclination. At 300km altitude, the satellite plunges back into the atmosphere, creating an artificial "shooting star" after a few weeks. Hence it is named NEGAI or gWish upon a shooting star.h In 30 degree inclination orbit, the satellite does not go beyond over 30 degrees latitude either north or south. In order to access better, three ground stations were constructed one in Soka University campus and others in two remote islands. Negaifs mission will be two-fold. It will serve as a test bed for a highly advanced information processing system with FPGA (Field Programmable Gate Array) that is extremely reliable and resistant to intense cosmic radiation. It also aims to spur interest in space exploration among children. Negaih contained on microfilm the names and dreams of children recruited through a public campaign. The most important aspect of this satellite is that it is hand-made by the students.
Satellite Commentary (in Japanese)
Memory of a Satellite Communication Engineer, Series #5
Preparing launch of CS digital broadcasting and J-3 satellite
"An internal study meeting for CS digital broadcasting was written at the last part of the previous article. It has been developing into the "SkyPerfect" business. The one performed concurrently at this period is the next communication satellite JCSAT-3 project. I participated in both two projects in order to combine these two. I'll write about a start-up period of the CS digital broadcasting as well as also the J-3 satellite at the current 5th and the next 6th (final)."
Space Japan Interview (in Japanese)
Learned from Development of CS "Sakura, Cherry in English", blooming in the universe of "Showa".
Islands satellite phone service and TV relay services, using 6/4 GHz satellite antennas and repeaters
Akio Iso, NICT
We have interviewed with Dr. Akio Iso about satellite phone and TV relay services provided for Japan's remote islands. He talks international situations in the early 1970s, when the Japan's communications satellite "Sakura" was embodied, the popularization of television and telephone, public telephone services in the future.
Satellite Communications and I (in Japanese)
Country styles learned from satellite links
Miho Fujieda, NICT
"NICT maintains and supplies the Japan Standard Time. In order to maintain the national standard times, it is necessary to compare the individual time standards among various countries, measuring precisely what you are going slowly or fast." The time comparison experiments have been conducted using a communication satellite. Miho Fujieda, who are engaging such experiments with China, India, Germany, Russia, etc., writes country styles learned from the experiments.
Satellite Communications and I (in English)
SKY Perfect JSAT Corporation
"Even if we have failed in the system, I try to act responsibly, considering what is the best for the customer at first, what we should do and how we prioritize" Ms. Miki Suzuki, SKY Perfect JSAT, appears in this issue's "Satellite Communications and I". She talks passion to experience the universe through high school, college to graduate studies in infrared astronomy, to recent jobs since the merger of three companies after joining.
