A STUDY OF THE BASIC CONCEPTS OF COMMUNICATION SATELLITES
ABSTRACT
A communication satellite is an orbiting artificial earth satellite that receives a communications signal from a transmitting ground station, amplifies and possibly processes it, then transmits it back to the earth for reception by one or more receiving ground stations. The study is to scrutinize the Basic Concepts of Communication Satellites. In achieving this aim, the following specific objectives were laid out to find out the factors mitigating the enhancement of Communication Satellites and examine the relevance of Communication Satellites in the development of Nigeria economy. The motivation that led to this research work is the rapid adoption of media streaming instead of linear media broadcasting and the urgent need to extend broadband coverage to underserved areas such as; developing countries, aero/maritime, and rural areas. Data used in this work is derived primary from secondary sources. The methodology therefore, is basically documentary in nature. This involves learning new facts and principles through the study of documents and records. The documents and records include journals, textbooks, newspapers, magazines, official publications etc. By putting together logically evidence derived from documents and records. Conclusion which either established facts hitherto unknown or sound generalization can be obtained. This study will be of immense benefit to other researchers who intend to know more on this study and can also be used by non-researchers to build more on their research work. This study contributes to knowledge and could serve as a guide for other study.
CHAPTER ONE
1.1 Introduction
Today’s communications satellites offer extensive capabilities in applications involving data, voice, and video, with services provided to fixed, broadcast, mobile, personal communications, and private networks users. A communication satellite is an orbiting artificial earth satellite that receives a communications signal from a transmitting ground station, amplifies and possibly processes it, then transmits it back to the earth for reception by one or more receiving ground stations. Communications information neither originates nor terminates at the satellite itself. The satellite is an active transmission relay, similar in function to relay towers used in terrestrial microwave communications (Plgpl, 2021).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitations of the Study and Definition of technical terms.
1.2 Background of Study
Since their inception, Satellite Communications (SatComs) have found a plethora of applications, including media broadcasting, backhauling, news gathering etc. Nowadays, following the evolution of Internet-based applications, SatComs are going through a transformation phase refocusing the system design on data services, namely broadband SatComs. Furthermore, a major milestone of the 5th generation of communication systems (5G) is the integration and convergence of diverse wired and wireless technologies. In this context, SatComs pave the way for seamless integration targeting specific use cases which can take advantage of their unique capabilities. In parallel, private ventures have led the development of a multitude of manufacturing and launching options, previously only reserved for governments and a handful of large international corporations (Plgpl, 2021).
Satellites face competition from other media such as fibre optics, cable, and other land-based delivery systems such as microwaves and even power lines. The main advantage of satellites is that they can distribute signals from one point to many locations. As such, satellite technology is ideal for “point-to-multipoint” communications such as broadcasting. Satellite communication does not require massive investments on the ground-making it ideal for underserved and isolated areas with dispersed populations.
Satellite communications technology is often used during natural disasters and emergencies when land-based communication services are down. Mobile satellite equipment can be deployed to disaster areas to provide emergency communication services. One major technical disadvantage of satellites, particularly those in geostationary orbit, is an inherent delay in transmission. While there are ways to compensate for this delay, it makes some applications that require real-time transmission and feedback, such as voice communications, not ideal for satellites.
Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the Basic Concepts of Communication Satellites.
1.3 Statement of Problems
Investigation reveals the challenge for the application of precoding in practical satellite systems is related to non-linearities. In fact, the on-board per-antenna traveling-wave-tube amplifiers (TWTAs) usually introduce non-linear effects, which result in a distortion on the transmitted waveforms. A typical solution to this problem in single-user links relies on predistortion techniques, but their extension to multi-beam systems relying on precoding is not straightforward, because of the mutual correlation between the data streams induced by the precoding schemes.
Very Low Earth Orbit (VLEO) platforms operate closer to the Earth than LEO satellites. This allows them to be simpler, smaller, and thus, cheaper (Llop et al., 2014). However, such low altitudes contain a denser part of the atmosphere, and therefore, larger aerodynamic forces. This can be seen as ame, but they can also represent an opportunity for orbit and attitude control (Virgili-Llop et al., 2019). Moreover, the increased drag represents a shortening of the orbital lifetime, but this also means a more frequent fleet replacement of smaller and cheaper spacecrafts, thus, becoming more responsive to technology and market changes (Dakka, 2018). Several private companies such as SpaceX, OneWeb or Telesat are planning to launch their Mobile Satellite Services (MSS) at VLEO.
