a constellation of#2
マレーシア航空370便について新たな捜索方法が行われております。それは，船と宇宙からの衛生を結びつけたものです。海には目印が無いため，海底捜索の船を出してもどこを航海したのかがわからなくなってしまいます。そこで船が通った場所を衛星で示すことで，記録をつけるというものです。記事の名で気になった単語は"constellation"です。『Wisdom英和辞典第三版（三省堂）』によると「星座，集合」などという意味がありました。ODでも"A group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure"と定義されております。人海戦術ですが，捜索ルートを記録していけばいつかは手がかりが見つかると思います。（Ume）
Boom in satellite ship tracking
The ship tracks recorded on this map are unmistakably those of a survey vessel moving back and forth on a grid.
They were produced by Fugro Equator, one of the ships currently making a detailed map of the ocean floor west of Australia as part of the search for wreckage from the lost Malaysia Airlines flight MH370.
The Dutch-owned Fugro Equator, together with the Chinese PLA-Navy ship Zhu Kezhen, which is working further to the south, are gathering bathymetric (depth) data over an area covering some 60,000 sq km.
Once this is in the hands of Australian authorities, the hunt for MH370 will go into a new phase, using a range of submersibles and other deepwater search technologies.
The maps on this page were recorded by exactEarth, one of a growing number of suppliers of ship tracking information acquired from space.
ExactEarth, a subsidiary of Canadian satellite component manufacturer ComDev, has a small constellation of sensors in orbit that can detect the Automatic Identification System (AIS) signals broadcast by ships.
