Challenge for communication through metallic atom layers -observation of the upper atmosphere and communication to the remote place-

在100 km高度附近的金属原子层是钠、铁等原子金属的层。提出了一种既可用于通信又可用于大气遥感观测的系统，并在TMU（东京首都大学）和NIPR（国家极地研究所）之间进行了实验。距离为5.3公里。进行了基本的发射和接收实验，并对观测和通信方法进行了进一步的研究，证明了该系统的可行性。

Metallic atom layers at around 100 km altitude are the layers of atomic metals such as sodium, iron etc. A system which can be used for telecommunication as well as atmospheric remote sensing observation was proposed and experiments were carried out between TMU (Tokyo Metropolitan University) and NIPR (National Institute of Polar Research). The distance was 5.3 km. Basic experiment of transmission and reception was executed, and further investigation of the observation and communication methods have proved that such a system is feasible.
