Abstract
Mobile satellite systems can be characterized as a major solution since they offer mobile communication services to users in different environments and for several significant purposes. In numerous conditions, satellite systems have exclusive competences in terms of broad coverage, robustness, broadcast, and multicast capabilities. However, the implementation of Land Mobile Satellite (LMS) systems still faces some limitations regarding connectivity and stability, leading to unreliable communication. Therefore, the target of this paper is to offer a comprehensive overview of land mobile satellite systems and services from various perspectives. This includes the classification of LMS systems, the operating frequency bands, and the representative Mobile Satellite Services (MSS) systems. The research challenges and future research are further described. Such information will contribute to the understanding of satellite systems and the currently faced issues that must be addressed.
Highlights
To date, modern satellite technology has facilitated our daily communications thanks to the idea of space-based communication, proposed by Arthur C
The scientific discovery of geostationary satellites served as the key in the subsequent development of modern satellite technologies [1]–[3]
According to [23], three satellites can generally provide global coverage. They can cover utmost of the earth’s area, but, the polar locations cannot be covered by Geostationary Earth Orbit (GEO) satellites, since there is a maximum latitude that can be covered from this type of orbit
Summary
Modern satellite technology has facilitated our daily communications thanks to the idea of space-based communication, proposed by Arthur C. That satellite was introduced as Sputnik 1, which is known as the first successful worldwide weather satellite This journey for orbiting superiority led to the founding of the nation’s early space programs and the launch of Explorer-1 in 1958, the first operational U.S satellite [6]. LMS systems can be used to actualize global personal communication networks [12], [13] by providing services such as finding location, radio paging, interconnection to the public switched telephone & private networks, voice communication, and data transmission to various terminals such as land vehicles, marine vessels, aircrafts, remote data collection with control sites, and moveable terminals. Research challenges and future studies are briefly described Such information will contribute to the understanding of satellite systems and the currently faced issues that must be addressed
