Book excerpt: The National Aeronautics and Space Administration (NASA) is investigating alternative approaches, technologies, and communication network architectures to facilitate building the Spaceports and Ranges of the future. These investigations support the Second Generation Reusable Launch Vehicle (2nd Gen RLV), Orbital Space Plane (OSP) and other associated craft presently under development or under consideration in Government, academic, and private sectors. These investigations also provide a national centralized R&D forum for next-generation Spaceport and Range technology development. Together, these sectors all share the common goal of changing the historic risk/reward equation for access to space, with the intent to: Dramatically reduce launch cost, Greatly improve launch system reliability, Significantly reduce crew risk. The shared and tacit goal is to achieve routine access to space. A fundamental paradigm shift is required to accomplish the desired goal. The historical approach of using dedicated and custom Range information equipment situated at relatively few and widely dispersed Spaceports as the only access to space must change before routine access to space can occur. This change is analogous to the historical transformation that occurred in aviation; moving from dedicated, remote test sites where test pilots first experimented with jet-propelled aircraft to today's thriving international and regional airports. Information networks at Spaceports and Ranges must transition to a total integration of existing, new, and emerging technologies that provide a new and robust way of interconnecting the Range assets, Range operations, and Range users during the launch event. This paradigm shift must occur despite the legacy of how the networks have evolved to this point. Instead of the dedicated, immobile, inflexible information infrastructures of today's Ranges and Spaceports, a more flexible approach is needed. Implicit in this flexibility is the need for modularization, to allow incorporation of newer technologies not yet imagined, without requiring scrapping future systems not yet even defined. The key is to envision a transition to a Space Based Range Distributed Subsystem, while enabling mobile and easy-to-reconfigure communication techniques around the edges of fixed, existing, information infrastructures. To enable this, the Emerging Communication Technology (ECT) research task documented in this report provides a keen vision of so-called First Mile technologies in support of NASA's Advanced Range Technology Working Group (ARTWG) and the Advanced Spaceport Technology Working Group (ASTWG) with the purpose of interconnecting mobile users with existing Range Communication infrastructures. Consistent with the goals originally identified for RISM (Range Information System Management) during the first year of this task, and continuing with the detailed research conducted on ECT during the second year of this ongoing research, this report details the results of researching and documenting the technical needs and technical characteristics of future Ranges, Range systems, and Range users. Specifically, this report explores Wireless Ethernet (Wi-Fi), Free Space Optical (FSO), and Ultra Wideband (UWB) communication technologies.

This book was released on 2014-11-19 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Aeronautics and Space Administration (NASA) is investigating alternative technologies to facilitate building communication networks for future Spaceports and Ranges. This reports documents an investigation conducted from October 2002 through September 2003 of an emerging communication technology known as Ultra Wideband (UWB) communication. Contained in this report is an overview of UWB communication technology, a survey of UWB equipment vendors, and complete details of the theoretical and experimental research that was performed during this emerging communication technology investigation. The summary conclusion of this report is that UWB communication holds great promise for augmenting future Spaceport and Range communication networks through enhancing short-range, high speed, wireless communication. This enhancement is accomplished through simultaneously integrating position-aware functions with traditional communication functions. UWB technology achieves this dual-function integration through using short impulses instead of the continuous waveforms common to most wireless systems. Because short impulses are used, UWB communication links are inherently immune to most multi-path interference, and also achieve better instantaneous spectrum re-use among users. UWB modulation also provides a Low-Probability-of-Detection (LPD) waveform with selectable security. UWB systems can therefore provide fade resistant, high speed data links wherever the presence of easily detectable wireless transmissions must be avoided, such as in specialized tactical situations. Despite the many theoretical advantages that exist for UWB modulation, much anxiety commonly arises with UWB emissions because of their ultra wide bandwidths. This characteristic especially causes concern vis-à-vis possible deleterious effects to narrowband legacy systems that typically operate at low link margins, such as GPS navigation systems, which often operate with link margins of only 1 or 2 dB. Though this concern has been addressed previously in Federal regulations through the inclusion of spectral emission mask requirements for UWB emissions, not all of the technical concerns have been settled. This report further researches some of these interference concerns by investigating UWB interference to, and UWB susceptibilities from, legacy wireless systems. The summary recommendation of this report is that UWB technology appears to hold many of the key advantages needed to tackle a number of wireless systems requirements needed in the future, provided it can co-exist successfully with both legacy narrowband wireless systems, and with other UWB wireless systems. Based on the demonstrated performance seen during testing, there is ample reason to believe that UWB wireless systems will be able to coexist with most legacy wireless systems. This report is a first step in understanding and assessing UWB's applicability for supporting the communication needs of future Spaceports and Ranges.

This book was released on 2011 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Explores near-term (less than 5 years) and longer-term (5-10 years) technologies that are candidates for enhancing the safety and security of hazardous materials transportation for use by shippers, carriers, emergency responders, or government regulatory and enforcement agencies. The report examines emerging generic technologies that hold promise of being introduced during these near- and longer-term spans. It also highlights potential impediments (e.g., technical, economic, legal, and institutional) to, and opportunities for, their development, deployment, and maintenance. The research focused on all modes used to transport hazardous materials (trucking, rail, marine, air, and pipeline) and resulted in the identification of nine highly promising emerging technologies."--Provided by publisher.
