Tutorial for analytical and scientific approaches related to LEO satellites ground station performance, including math, experiments, and simulations. Ground Station Design and Analysis for LEO satellites provides complete instructions and steps for ground station performance evaluation, including stations dedicated for scientific or communication purposes, and offers the reader an enhanced learning experience by proposing 40 ideas related to ground station performance assessment. Each idea goes over the math analysis, experiment or simulation, the methodology applied, the results, and a conclusion. This approach provides the reader with the opportunity to compare theoretical results with on-site results, guiding the reader towards intelligent and practical performance evaluation and enhancement. The text also considers the future emerging developments of LEO satellites and their challenges and applications, including multimedia and other scientific applications. Stemming from the highly qualified author’s research work of roughly 20 years, Ground Station Design and Analysis for LEO Satellites includes information on: Interference aspects, covering intermodulation interference modeling for LEO satellite ground stations and downlink adjacent interference for LEO search and rescue satellites Sun synchronization, covering nodal regression and Sun synchronization of low Earth orbits through inclination angle. Horizon plane and communication duration, covering communications duration with LEO satellites under ideal, practical and designed horizon plane for LEO satellite ground stations Figure of merit and system noise temperature, covering composite and antenna noise temperature, Sun noise experiment and desensibilization measurements at LEO satellite ground stations Ground Station Design and Analysis for LEO Satellites is an innovative and advanced tutorial-based resource that will appeal to satellite engineers (operators/vendors) working on the operation, maintenance, and performance evaluation of ground stations, as well as postgraduate students/early-stage researchers wishing to obtain knowledge on this state-of-the-art technology.

The potential threat posed by Leonid meteroids to orbiting spacecraft over the next several years calls for new dynamic mitigation strategies to assist the satellite community in reducing the danger to its vehicles. This book offers deliberate dynamic mitigation strategies to complement the traditional shielding strategies, providing mission operators additional ways to decrease the danger. Five different attitude control and orbit maneuvering options are examined in detail. The information is presented in algorithmic form to allow technically competent, but meteoroid inexperienced, operators to easily understand the phenomena, assess the danger, and implement procedures. Although general in scope, the book emphasizes the Leonid meteor events of the 1998-2002 timeframe.

This book describes multi-site diversity modelling of induced rain attenuation statistics for satellite communication systems using copula functions. It gathers all relevant state-of-the-art knowledge, provides the missing pieces and rounds them up in a way that the reader is given a complete picture of important modelling factors and ways to address them. The books’ main features include: Data post-processing methodology for statistical analysis based on our Earth-satellite propagation experiments. Two novel multi-site diversity prediction models based on Gaussian copula considering distance between stations or considering distance, baseline, and elevation angle. Two novel multi-site diversity prediction models based on hyperbolic cosecant copula considering distance between stations or considering distance, baseline, and elevation angle. Exhaustive comparative tests and error performance of the prediction models showing that improved error performance is achieved compared to the ITU R model and to the state-of-the-art models. The results presented in the book are expected to contribute to the improvement of the system design and to the further research of modelling the next generation satellite links at higher frequencies.

The accurate design of earth–space systems requires a comprehensive understanding of the various propagation media and phenomena that differ depending on frequencies and types of applications. The choice of the relevant channel models is crucial in the design process and constitutes a key step in performance evaluation and testing of earth–space systems. The subject of this book is built around the two characteristic cases of satellite systems: fixed satellites and mobile satellite systems. Radio Wave Propagation and Channel Modeling for Earth–Space Systems discusses the state of the art in channel modeling and characterization of next-generation fixed multiple-antennas and mobile satellite systems, as well as propagation phenomena and fade mitigation techniques. The frequencies of interest range from 100 MHz to 100 GHz (from VHF to W band), whereas the use of optical free-space communications is envisaged. Examining recent research advances in space-time tropospheric propagation fields and optical satellite communication channel models, the book covers land mobile multiple antennas satellite- issues and relative propagation campaigns and stratospheric channel models for various applications and frequencies. It also presents research and well-accepted satellite community results for land mobile satellite and tropospheric attenuation time-series single link and field synthesizers. The book examines aeronautical communications channel characteristics and modeling, relative radio wave propagation campaigns, and stratospheric channel model for various applications and frequencies. Propagation effects on satellite navigation systems and the corresponding models are also covered.

ISBN:

The only work to present a unified treatment of all the basic aspects of satellite communications and to give practical examples from real systems. Whereas most texts in the field concentrate on a mathematical description of the communications link, Satellite Communications gives the reader a thorough knowledge of the subject by going on to cover orbits, propagation, and the equipment that comprises a working system. Pratt and Bostian go beyond the standard treatment of ideal channels (which ignores some very real practical limitations) to deal with the problems associated with transmitting digitally modulated signals through real satellites and earth stations. Included are chapters on orbital mechanics, spacecraft construction, satellite-path radio wave propagation, modulation techniques, multiple access, and a detailed analysis of the communications link. Contains worked examples and homework problems based on current industrial practice.
