What are some key concepts and topics covered in the book?
The book Satellite Communication by Timothy Pratt covers a wide range of concepts and topics related to satellite communication systems. Some of these concepts and topics are:
Satellite orbits and geometry
This topic covers the different types of satellite orbits (such as geostationary orbit, medium-Earth orbit, low-Earth orbit) and their geometrical properties (such as altitude, inclination, eccentricity, period, velocity, the satellite position, velocity, and acceleration in different coordinate systems (such as Earth-centered inertial, Earth-centered Earth-fixed, topocentric-horizon, and orbital elements). It also covers how to determine the satellite coverage area, visibility, and elevation angle from a given location on Earth.
Satellite link design
This topic covers how to design a satellite link for a given application and performance requirement. It involves calculating the link budget, which is the balance of power and noise between the transmitter and the receiver of the satellite link. It also involves selecting the appropriate frequency band, antenna size, polarization, modulation scheme, coding scheme, and power amplifier for the satellite link. It also covers how to account for the effects of atmospheric attenuation, rain attenuation, scintillation, and depolarization on the satellite link.
Modulation and multiplexing techniques
This topic covers the various modulation and multiplexing techniques used in satellite communication systems. Modulation is the process of changing the characteristics of a carrier signal (such as amplitude, frequency, or phase) according to a message signal (such as analog or digital) to transmit information. Multiplexing is the process of combining multiple message signals into a single carrier signal to increase the efficiency and capacity of the transmission channel. Some of the common modulation and multiplexing techniques used in satellite communication systems are amplitude modulation (AM), frequency modulation (FM), phase modulation (PM), amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK), quadrature amplitude modulation (QAM), pulse code modulation (PCM), time division multiplexing (TDM), frequency division multiplexing (FDM), code division multiple access (CDMA), orthogonal frequency division multiplexing (OFDM), and more.
Multiple access schemes
This topic covers the different multiple access schemes that allow multiple users to share a satellite channel without interfering with each other. Some of the common multiple access schemes used in satellite communication systems are frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), space division multiple access (SDMA), and orthogonal frequency division multiple access (OFDMA). Each of these schemes has its own advantages and disadvantages in terms of bandwidth efficiency, complexity, synchronization, interference management, and scalability.
Error control coding
This topic covers the principles and methods of error control coding for satellite communication systems. Error control coding is the process of adding redundancy to a message signal to detect and correct errors that may occur during transmission due to noise or interference. There are two main types of error control coding: block coding and convolutional coding. Block coding is a method of dividing a message into fixed-length blocks and adding extra bits to each block to form a code word. Convolutional coding is a method of passing a message through a shift register and combining its outputs to form a code word. Some of the common error control codes used in satellite communication systems are Hamming code, cyclic code, Reed-Solomon code, Bose-Chaudhuri-Hocquenghem code, convolutional code, Viterbi code, turbo code, low-density parity-check code, and more.
Propagation effects and interference
This topic covers the effects of atmospheric propagation and interference on satellite communication signals. Atmospheric propagation refers to the interaction of electromagnetic waves with the Earth's atmosphere as they travel from the transmitter to the receiver. Some of the atmospheric propagation effects that affect satellite communication signals are ionospheric effects (such as refraction, dispersion, scintillation, faraday rotation), tropospheric effects (such as attenuation, refraction, scintillation, and fading), and rain effects (such as attenuation, depolarization, and scattering). Interference refers to the unwanted signals that affect the quality and reliability of the desired signal. Some of the sources of interference that affect satellite communication signals are co-channel interference (from other satellites or terrestrial stations using the same frequency), adjacent channel interference (from other satellites or terrestrial stations using nearby frequencies), intermodulation interference (from the nonlinear mixing of signals in the satellite or terrestrial equipment), and jamming interference (from intentional or unintentional transmission of noise or signals to disrupt the communication).
Satellite networks and applications
This topic covers some of the current and emerging satellite networks and applications in various domains. Satellite networks are systems of satellites and ground stations that provide communication services to users. Some of the common types of satellite networks are fixed satellite service (FSS), mobile satellite service (MSS), broadcast satellite service (BSS), global navigation satellite system (GNSS), and Earth observation satellite system (EOSS). Satellite applications are the specific uses of satellite communication for various purposes. Some of the common satellite applications are telephony, television, radio, internet, navigation, remote sensing, weather forecasting, disaster management, military operations, space exploration, and more.
