Application of advanced technology to space automation

Automated operations in space provide the key to optimized mission design and data acquisition at minimum cost for the future. The results of this study strongly accentuate this statement and should provide further incentive for immediate development of specific automtion technology as defined herein. Essential automation technology requirements were identified for future programs. The study was undertaken to address the future role of automation in the space program, the potential benefits to be derived, and the technology efforts that should be directed toward obtaining these benefits

MicroComputer and Local Government

In 1976, two young Californians named Steve Jobs and Steve Wozniak started a revolution. It was a quiet revolution... no shots were fired... no demonstrations occurred... there were no casualties, but it was a revolution nevertheless... a revolution that will have long-lasting results. That year these two young men developed the Apple, the first commercially successful microcomputer

Microcomputers and City Governments

In 1976 a revolution occurred. blood was shed, but the effects No shots were fired, no of the revolution in electronic data processing have been felt throughout the country. What is more, its effects will continue to be felt for many years to come

Preliminary Candidate Advanced Avionics System (PCAAS)

Specifications which define the system functional requirements, the subsystem and interface needs, and other requirements such as maintainability, modularity, and reliability are summarized. A design definition of all required avionics functions and a system risk analysis are presented

Data systems elements technology assessment and system specifications, issue no. 2

The ability to satisfy the objectives of future NASA Office of Applications programs is dependent on technology advances in a number of areas of data systems. The hardware and software technology of end-to-end systems (data processing elements through ground processing, dissemination, and presentation) are examined in terms of state of the art, trends, and projected developments in the 1980 to 1985 timeframe. Capability is considered in terms of elements that are either commercially available or that can be implemented from commercially available components with minimal development

A Proposal for the Development of a Program of the Use of Microcomputers in the Red Hill School District

In this study the current uses of microcomputers in the classroom were explored through a review of the literature and personal interviews with educators, businessmen, and computer specialists. The current innovations are examined in an effort to anticipate the technical world that students will face in the future. One must anticipate what the future needs will be to develop a program that will help the students to become contributing members of society. This study was specifically conducted to make recommendations for the uses of microcomputers in the Red Hill school district. The report focuses on the different areas of the instructional uses of microcomputers in the classroom. These different areas are: the selection and evaluation of hardware; the selection and evaluation of software; microcomputers and minicomputers; time-sharing and main frame computers; computer literacy; computer programming; drill and practice; tutorial; creative programming; computer-managed instruction; computer-assisted instruction; projected uses in the classroom by subject material; simulations and decision making; games and graphics in the classroom; introduction into the curriculum; telecommunications and their use in education; peripherals that are desirable and necessary; the choice of a supplier; computer equity and students; microcomputer politics and solutions; computer phobia and its solutions; social implications of the microcomputer; are computers cost effective; the hidden costs of microcomputers; the administrator\u27s role in adopting the microcomputer into the curriculum; microcomputers and copyright laws; microcomputers in a rural district; the funding available for microcomputer programs; why computers are not reaching their full potential; new innovations and the future; the resources available at Red Hill; and preventative maintenance and care. From the discussion of these areas, a list of specific recommendations for the instructional use of microcomputers at Red Hill is formed. Following these recommendations, a tentative timetable of adoption is presented

VLSI Multiple Microcomputer Technology Applied to Real-Time Simulators

VLSI technology, embodied in state of the art microprocessors and microcomputers, has implied a computer system architecture that offers the possibility for extensive standardization, modularity, and performance improvements that can significantly impact and reduce the lifetime costs of real-time simulators. This report discusses one such system. Both the hardware and software aspects of the system are examined

Deep Space Network information system architecture study

The purpose of this article is to describe an architecture for the Deep Space Network (DSN) information system in the years 2000-2010 and to provide guidelines for its evolution during the 1990s. The study scope is defined to be from the front-end areas at the antennas to the end users (spacecraft teams, principal investigators, archival storage systems, and non-NASA partners). The architectural vision provides guidance for major DSN implementation efforts during the next decade. A strong motivation for the study is an expected dramatic improvement in information-systems technologies, such as the following: computer processing, automation technology (including knowledge-based systems), networking and data transport, software and hardware engineering, and human-interface technology. The proposed Ground Information System has the following major features: unified architecture from the front-end area to the end user; open-systems standards to achieve interoperability; DSN production of level 0 data; delivery of level 0 data from the Deep Space Communications Complex, if desired; dedicated telemetry processors for each receiver; security against unauthorized access and errors; and highly automated monitor and control

NASA. Lewis Research Center Advanced Modulation and Coding Project: Introduction and overview

The Advanced Modulation and Coding Project at LeRC is sponsored by the Office of Space Science and Applications, Communications Division, Code EC, at NASA Headquarters and conducted by the Digital Systems Technology Branch of the Space Electronics Division. Advanced Modulation and Coding is one of three focused technology development projects within the branch's overall Processing and Switching Program. The program consists of industry contracts for developing proof-of-concept (POC) and demonstration model hardware, university grants for analyzing advanced techniques, and in-house integration and testing of performance verification and systems evaluation. The Advanced Modulation and Coding Project is broken into five elements: (1) bandwidth- and power-efficient modems; (2) high-speed codecs; (3) digital modems; (4) multichannel demodulators; and (5) very high-data-rate modems. At least one contract and one grant were awarded for each element
