Book excerpt: This thesis designs, develops, and uses software Graphical User Interfaces (GUIs) to analyze the communications capabilities of Radio Frequency (RF) Inter-Satellite Links (ISLs). The GUIs are geared towards analyzing the proposed ISLs of the Discoverer II program, but are general enough to permit analysis of any free-space RF ISLs. Discoverer II is a demonstration program of low-earth orbiting satellites and is primarily focused on satellite-based sensor technology. This thesis shows RF ISLs can meet the program requirement to broadcast the sensor data back to CONUS in near-real-time. The GUIs operate in real-time and explore trade-offs in the communications capability by varying the requirements, parameters, and components of the system design. Three GUIs are developed. The first GUl uses parameters from an assumed satellite constellation geometry to calculate the operating range of the ISLs. The second GUl solves for an unknown parameter of the communications system when all other parameters are given. The third GUl extends the analysis capability by plotting the trade-off between two parameters over a specified range of data. The analysis of the Discoverer II ISLs indicates that antenna radius is a very significant factor in the trade-off analysis, as well as being an important satellite design parameter.

Book excerpt: In response to a request from the Defense Advanced Research Projects Agency, the committee studied a range of issues to help identify what strategies the Department of Defense might follow to meet its need for flexible, rapidly deployable communications systems. Taking into account the military's particular requirements for security, interoperability, and other capabilities as well as the extent to which commercial technology development can be expected to support these and related needs, the book recommends systems and component research as well as organizational changes to help the DOD field state-of-the-art, cost-effective untethered communications systems.

Book excerpt: This is the final report on a study of laser-based intersatellite communications links. Three links are considered: between geostationary satellites, between geostationary and inclined geosynchronous satellites, and between geostationary and low earth orbit satellites. Section 1 provides historical & technical background on laser communications systems and an outline of ongoing optical intersatellite link (ISL) development programs. Section 2 analyzes the operational parameters of the three links under study. Section 3 reviews optical ISL technology and the current or projected performance of ISL components. Link gains & losses are identified in section 4 for both direct detection & heterodyne receivers and for direct modulation laser diodes & externally modulated gas & solid state lasers. Section 5 discusses the acquisition & tracking functions that are essential before data transmission can begin. Section 6 presents the conceptual design for the baseline direct detection system operating at 100 megabytes per second and for two options at one gigabyte per second. Performance parameters are listed for the baseline system with changes indicated for the two optional systems. A telescope is selected and the optical bench dimensions are established for all three systems. An outline is presented for the electrical system which supports the communications signal and controls the system for acquisition & tracking. The final sections review Canadian capabilities in optical ISL and outline a roadmap to achieve a Canadian presence in the optical ISL market.

Available in PDF, EPUB and Kindle. Book excerpt: Presents the concepts, technology, and role of satellite systems in support of personal applications, such as mobile and broadband communications, navigation, television, radio and multimedia broadcasting, safety of life services, etc. This book presents a novel perspective on satellite systems, reflecting the modern personal technology context, and hence a focus on the individual as end-user. The book begins by outlining key generic concepts before discussing techniques adopted in particular application areas; next, it exemplifies these techniques through discussion of state-of-art current and emerging satellite systems. The book concludes by contemplating the likely evolution of these systems, taking into consideration influences and trends in technology, in conjunction with growing user expectations. In addition to addressing satellite systems that directly interact with personal devices, the book additionally considers those indirect applications where there is an increasing interest by individuals - notably, in remote sensing. As such, the book uniquely encompasses the entire gamut of satellite-enabled personal / end-user applications. Key Features: Broad scope - views satellite systems generically with regards to their applicability across a wide range of personal application areas Strong foundation in underlying concepts State-of-the-art system examples Review of trends in relevant areas of satellite technology Revision questions at the end of each chapter The book is suited to individuals, engineers, scientists, service providers, system operators, application developers and managers interested or involved in the use of satellite technology for personal applications. It should also hold interest for use in research institutes interested in promoting inter-disciplinary cross-fertilization of ideas, as well as by financiers, policy makers, and strategists interested in gaining a better understanding of this technology.

This book was released on 2009 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of antenna arrays to exploit spatial information in single and multi-user RF communication receivers is well established for reducing interference and enabling frequency reuse. Antenna arrays have been deployed in single satellite applications but arrays have not been exploited in multi-satellite constellations where increased array size enables high spatial selectivity between ground transmitters. One requirement for these array systems is sufficient fidelity in transporting the received RF signals at each antenna to the array processor. Optical inter-satellite link architectures for signal transport are investigated and parameterized models to compare the performance of each are synthesized. Both analog and digital modulation schemes for the link are considered. A two-channel receiver with both low and high interference is analyzed. It is shown that high resolution satellite array receivers are practical with low required optical power. The optimum selection of transport architecture is shown by selecting for lowest error probability or minimum required optical power. A satellite-to-satellite distance threshold is found for selecting the optimum inter-satellite link architecture for a given application.
