一、楼顶卫星通信天线为了在发生强烈地震等巨大灾害造成通信网中断不通的情况下,能利用卫星通信保持最必须的通信联络的目的,开展了卫星通信的研究,现已在铁研所楼顶上设置了地面站。这项研究由铁研所与邮电部无线电研究所合作进行。铁研所地面站与无线电研究所鹿岛基地站之间,通过同步卫星“樱”来联络。今年开展了因雨无线电波衰减而影响回线质量的研究课题。二、结构物试验地坑地坑内可做各种结构物实物或大型模型的试验。地坑内径14米,深3.15米。在地坑周围
First, the roof satellite communication antenna In the event of a strong earthquake and other huge disasters caused by communication network interruption, the use of satellite communications can maintain the most necessary communication purposes, to carry out satellite communications research is now in the Iron Institute On the roof set up a ground station. The research was conducted in collaboration with the Institute for Radio Research, Ministry of Posts and Telecommunications. Tie Institute ground station and Radio Institute Kashima base station, through the synchronization satellite “Sakura” to contact. This year launched a study on the quality of return lines due to the attenuation of rainy-wave radio waves. Second, the structure test pit can do a variety of structures or large-scale model of the test. Pit diameter of 14 meters, 3.15 meters deep. Around the pit
