Satellite Terrestrial Integrated mobile Communication System as a disaster countermeasure

Creating a safer society requires communication methods available during disasters. This need has prompted the start of research and development to build a mobile satellite communication system for the satellite terrestrial common terminal. The system is called STICS (Satellite/Terrestrial Integrated mobile Communication System). A dual communication function that can connect to both the terrestrial system and the satellite system is formed by using a common terminal with a portable, handheld shape. This paper discusses the research and development and the current status of STICS.
