Design and analysis for future satellite IoT communication systems

Abstract

As the satellite industry has expanded, much progress has been made in development costs, payload technology, and launch vehicle technology, which were previously burdensome. As a result, attention is focused on low-Earth orbit (LEO) satellites with the advantages of cost-effectiveness, easy deployment, and wide coverage. Large global companies are entering the LEO constellation satellite business, and many satellites have already been launched and it is expected that global coverage will be possible within the next few years. Accordingly, satellite Internet of Things (IoT) communication technology is also receiving attention as a major application technology, and its main uses include environmental monitoring, emergency management, smart cities, logistics and shipping management, etc., which require low power and low data rates and are occasionally used. It is being considered for conveying and utilizing the collected data. In this study, we attempted to design and analyze a future-oriented system in the field of satellite IoT communication. To this end, we deal with Direct-to-Satellite IoT (DtS-IoT) communication, space-air-sea integrated network-based satellite IoT communication, and joint communication and radar sensing (JCAS)-based satellite IoT communication.
