Framework and Challenges for Mobile Satellite System

Abstract

In satellite communications, as in other businesses, the demand for broadband has increased. Satellites carry global client information, including satellite TV, radio, and the Internet, via spacecraft. Satellite communication also provides global speech delivery. They are also vital for the recovery of natural disasters and other emergencies, as communications following natural disasters are crucial. While some spacecrafts are used primarily for data delivery, all spacecraft require communications systems. For example, remote satellites may collect environmental data, but both the data gathered and the satellites’ locations are unknown. The limited storage capacity on board necessitates a high-speed data connection in order to prevent data loss when collecting massive amounts of information. The use of satellites to communicate with others, such as (interplanetary) space, necessitates the creation of new algorithms and protocols for each network tier; satellite communication is constrained by the relatively narrow bandwidth and high transmission power required for satellite transmission. The rising demand for high-speed data impacts the whole telecoms and satellite communications industry. Continuing demand growth and dynamically shifting markets are the key drivers of satellite communication trends.
