Abstract

日本は国土の66%が森林であり,そのうち約40%が人工林である.現在,林業では,樹齢50年以上の木には間伐等を行って森林管理を行っている.高分解能の衛星写真により個々の樹冠を観測することで,宇宙から間伐の必要性の有無を判断することが可能である.信州大学では,5m分解能の光学系を用いて森林リモートセンシングを行い,特にヒノキの樹冠観測を行う人工衛星「こもれび」の研究を行ってきた.また,本衛星は技術試験として可視光通信を行うためのLEDを8個搭載している.本論文は「こもれび」の概要とミッションについてまとめたものである.

The area of forest land in Japan accounts for about 66% of the country's area and about 40% of them are man-made forests. At present, these main plantations with about 50-years-old trees must be managed by thinning or selection cutting. For that purpose, high-resolution data based on an individual tree crown are necessary. Shinshu University has been studying a 50 kg-class micro-satellite named "KOMOREBI" with 5m spatial resolution for forest remote sensing, especially for observing the tree crowns of Cahmaecyparis obtuse. And it has 8 LEDs for visible light communication(VLC) as a technological demonstration. This paper summarizes the concept and missions of "KOMOREBI".
