Book Description
The aim of the work was to identify the key factors involved in the use of alternate spectrum in various bands for a future integrated CNS data link. The study focused on systems and spectral bands that can deliver VDL-or-higher data rates in a two-way communication setting (including air-ground, ground-air, and air-air modes of operation), with multiple platforms (aircraft) operating in the same local environment. We begin with a review of the initial task list, and the final task list. The final task list contained a focus upon spectral availability and related systems that could be affected by the deployment of a new aviation data link (ADL) system. Most of this addresses the lower few layers of the communications protocol stack. A brief review of current related efforts in the aeronautical community is then provided, in which we describe several systems and programs of interest. Participation in some of these efforts is recommended. We also delineate several of the advantages and disadvantages of these system/efforts, in view of anticipated requirements of a new ADL. Desired attributes of a new ADL system are then discussed, and a connection with existing systems is made. The need to consider a wider set of alternative systems and technologies is described, and the beneficial aspects of a particular transmission technique- spread spectrum-are discussed. We then discuss in more detail several potential spectral regions, in terms of propagation conditions, available technology, spectrum availability, and waveform selection. Some comments on the need for standardization are also provided. We note that none of the existing systems described will likely meet the full range of desired features of a new ADL, but that several systems and spectral regions offer promise in terms of one or more characteristics. A system design and analysis approach is then provided. In this, we again focus on the lower few layers of the protocol stack, and aim to capture the main features

Category : Technology & Engineering
Languages : en
Pages : 196
Book Description
Real-Time Ground-Based Flight Data and Cockpit Voice Recorder Unique text determining the feasibility for implementation and manufacture of ground-based black box systems Real-Time Ground-Based Flight Data and Cockpit Voice Recorder helps familiarize the reader with the nature of issues surrounding existing black box technology integrated on aircrafts and to understand the benefits and importance of proposed real-time ground-based alternative solutions. These are based on predicting aircraft problems while in flight, including understanding the feasibility of using the already existing space and ground-based wireless technologies infrastructures for this purpose. The authors discuss expense reductions in the crash investigation when implementing the new concepts in this book as compared to existing procedures when aircraft accidents occur. The text also opens new research ideas for future investigations. Simulation codes are included to allow for further independent exploration into the covered concepts and ideas. Topics covered in the book include: Satellite Data Transfer Implementation, including basics of the technology, channel data rate, PSTN-based satellite implementation, and expected availability of spectrum Very High Frequency Digital Link (VDL), including modes, sublayers, data transfer, packet and frame structure, and number of channels needed to support a certain number of airplanes Modern Airplane Communication Technologies (including direct air-to-ground communication using 5G) and terahertz band communications; and their integration into aviation communications Black box final architecture and connectivity, including ground and UAV connectivity, and general black box wireless communications challenges For aviation industrial engineers and technical staff, managers, and aerospace and academic researchers, Real-Time Ground-Based Flight Data and Cockpit Voice Recorder is a valuable guide to existing and future technology to successfully predict aircraft problems during flight.
