    A strapdown mechanization and associated Kalman filter are developed to provide both ground align and airstart capabilities for inertial navigation systems (INSs) using Doppler velocity and position fixes, while not requiring an initial heading estimate. Position update during coarse mode is possible by defining sine and cosine of wander angle as filter states and modeling the position error in ge... View full abstract»

    To provide a controlled environment, changes to the Space Shuttle primary avionics system software have been grouped into operational increments (OIs) that identify a predefined set of changes and discrepancy corrections (a baseline) for that OI. Two early processes implemented were an automated configuration management database and a prologue in all the code modules. This allows a causal analysis... View full abstract»

    It is shown that integrated flight and fire control modes, analogous to those used in fixed-wing applications, can be implemented to enhance an attack helicopter's air-to-air and air-to-ground combat effectiveness. With fly-by-wire active flight controls and state-of-the-art technology in target acquisition and tracking, integrated flight/fire control can increase firing opportunities, improve wea...

  • Tools and techniques for estimating high intensity RF effects

    Publication Year: 1992, Page(s):24 - 31
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (768 KB)

    Tools and techniques for estimating and measuring coupling and component disturbance for avionics and electronic controls are described. A finite-difference-time-domain (FD-TD) modeling code, TSAR, used to predict coupling is described. This code can quickly generate a mesh model to represent the test object. Some applications as well as the advantages and limitations of using such a code are desc... View full abstract»

    The cellular automata (CA) concept is introduced, and it is shown how it is applied to situation assessment in connection with digital map-based tasks. The demonstration system makes use of 11480 virtual processors. Although the use of the CA paradigm was motivated by projections of future availability of massively parallel hardware, the CA algorithms have run efficiently on ordinary serial comput...

  • Design for validation

    Publication Year: 1992, Page(s):38 - 43
    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (595 KB)

    An approach is outlined for the development of ultrareliable avionics for civil air transports using a design-for-validation philosophy that includes rigorous application of formal methods. The basic concept of the methodology is introduced, and the role of formal methods is explored. The impact of the design-for-validation philosophy on the system design process is then demonstrated by two simple... View full abstract»

  • Digital avionics-an international perspective

    Publication Year: 1992, Page(s):44 - 45
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (172 KB)

    It is maintained that the dynamism of electronics technology, especially in displays, microprocessors and software, makes for exciting promises and problems in avionics. International barriers are disappearing, and the trends towards downsizing, new alliances, and consolidation should ultimately lead to a stronger avionics industry worldwide.<> View full abstract»

  • Electrical power on a 30 kW space-based radar satellite

    Publication Year: 1992, Page(s):46 - 50
    Cited by:  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (408 KB)

    An electrical power system for a space-based radar satellite is described. When the radar is on, its transmitter needs an average DC power of 30 kW. The problem of distributing the power efficiently in pulses to many transmit/receive modules is addressed. System requirements include a high-voltage battery and transmission line, load-sharing between the solar array, and the battery during sunlit pe... View full abstract»
