Research on Key Technologies of Satellite Mobile Communication System

The mobile communication service will not be constrained by the terrain and yet has good communication advantages in remote mountainous locations, islands, and other areas. Satellite mobile communication systems can offer a wide range of mobile communication services to customers throughout the world. The building of a satellite mobile communication system with worldwide coverage is the unavoidable trend of China's future satellite communication system construction given the development plan of China's national interests' globalization and the necessity for information security. There are currently 20 million prospective users of satellite mobile communication, which has seen a sharp increase in demand in recent years. However, the global demand for the entire region cannot be satisfied by the satellite mobile communication system's coverage. The global demand for phone, data, and other low bit rate services cannot be satisfied by the satellite mobile communication system's coverage, which can only offer voice and data services. As a result, efforts must be made to investigate novel technologies and approaches that can be used to address the fundamental technological issues with satellite mobile communication systems. The development of satellite mobile communication systems is compared in this paper, along with the key research directions for the problems with satellite load antenna, on-satellite processing, and inter-satellite link, all of which are crucial for the development of satellite mobile communication systems.
