This book was released on 2018-07-24 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: A description is given of a data distribution satellite (DDS) system. The DDS would operate in conjunction with the tracking and data relay satellite system to give ground-based users real time, two-way access to instruments in space and space-gathered data. The scope of work includes the following: (1) user requirements are derived; (2) communication scenarios are synthesized; (3) system design constraints and projected technology availability are identified; (4) DDS communications payload configuration is derived, and the satellite is designed; (5) requirements for earth terminals and network control are given; (6) system costs are estimated, both life cycle costs and user fees; and (7) technology developments are recommended, and a technology development plan is given. The most important results obtained are as follows: (1) a satellite designed for launch in 2007 is feasible and has 10 Gb/s capacity, 5.5 kW power, and 2000 kg mass; (2) DDS features include on-board baseband switching, use of Ku- and Ka-bands, multiple optical intersatellite links; and (3) system user costs are competitive with projected terrestrial communication costs.

Book Synopsis Duplex Direct Data Distribution System by : National Aeronautics and Space Adm Nasa
Download or read book Duplex Direct Data Distribution System written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2018-09-19 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NASA Glenn Research Center (GRC) is developing and demonstrating communications and network technologies that are helping to enable the near-Earth space Internet. GRC envisions several service categories. The first of these categories is direct data distribution or D3 (pronounced "D-cubed"). Commercially provided D3 will make it possible to download a data set from a spacecraft, like the International Space Station. as easily as one can extract a file from a remote server today, using a file transfer protocol. In a second category, NASA spacecraft will make use of commercial satellite communication (SATCOM) systems. Some of those services will come from purchasing time on unused transponders that cover landmasses. While it is likely there will be gaps in service coverage, Internet services should be available using these systems. This report addresses alternative methods of implementing a full duplex enhancement of the GRC developed experimental Ka-Band Direct Data Distribution (D3) space-to-ground communication link. The resulting duplex version is called the Duplex Direct Data Distribution (D4) system. The D4 system is intended to provide high-data-rate commercial direct or internet-based communications service between the NASA spacecraft in low earth orbit (LEO) and the respective principal investigators associated with these spacecraft. Candidate commercial services were assessed regarding their near-term potential to meet NASA requirements. Candidates included Ka-band and V-band geostationary orbit and non-geostationary orbit satellite relay services and direct downlink ("LEO teleport") services. End-to-end systems concepts were examined and characterized in terms of alternative link layer architectures. Alternatives included a Direct Link, a Relay Link, a Hybrid Link, and a Dual Mode Link. The direct link assessment examined sample ground terminal placements and antenna angle issues. The SATCOM-based alternatives examined existing or pr
Book Synopsis Viewing the Earth by : Pamela Etter Mack
Download or read book Viewing the Earth written by Pamela Etter Mack and published by MIT Press. This book was released on 1990 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viewing the Earth examines the role played by interest groups in shaping the process of technological change, offering valuable insights into how technologies evolve. It traces the history of Landsat from its origins through the launch and use of the first few satellites, showing how a variety of forces shape the form and the eventual reception of any new technology. The Landsat earth resources satellite system was a project of The National Aeronautics and Space Administration that was created to collect data about earth resources from space. The first satellite was launched in 1972 with great fanfare and high expectations. The data proved useful for everything from finding oil to predicting harvests, yet today the successful commercialization of the program is still uncertain. Why? To answer this question, Pamela E. Mack focuses on the negotiating process that went on among different parts of the space agency, other interested government agencies, and various organizations that were potential users of the data. This formal and informal negotiating process, she points out, involved not only choices between alternative technologies and the satellite but also conflicting definitions of what the satellite would do. The story is full of fascinating detail, from the concerns of the intelligence community over civilian satellites looking at the earth to the politics of agricultural survey. Pamela E. Mack is Associate Professor in the History Department at Clemson University.

Book Synopsis Introduction to Space Systems by : Miguel A. Aguirre
Download or read book Introduction to Space Systems written by Miguel A. Aguirre and published by Springer Science & Business Media. This book was released on 2012-08-16 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definition of all space systems starts with the establishment of its fundamental parameters: requirements to be fulfilled, overall system and satellite design, analysis and design of the critical elements, developmental approach, cost, and schedule. There are only a few texts covering early design of space systems and none of them has been specifically dedicated to it. Furthermore all existing space engineering books concentrate on analysis. None of them deal with space system synthesis – with the interrelations between all the elements of the space system. Introduction to Space Systems concentrates on understanding the interaction between all the forces, both technical and non-technical, which influence the definition of a space system. This book refers to the entire system: space and ground segments, mission objectives as well as to cost, risk, and mission success probabilities. Introduction to Space Systems is divided into two parts. The first part analyzes the process of space system design in an abstract way. The second part of the book focuses on concrete aspects of the space system design process. It concentrates on interactions between design decisions and uses past design examples to illustrate these interactions. The idea is for the reader to acquire a good insight in what is a good design by analyzing these past designs.
