Step 1 resulted in a baseline architecture definition. In Step 2 the architecture definition will be developed and validated as the Software Communications Architecture (SCA) which will be the basis for future DoD software radios. The SCA is also expected to become the standard for Government and commercial software radios. Step 3 activities will result in procurement and integration of systems and waveforms that are compliant with the SCA and which satisfy individual DoD user requirements. During Step 3, the architecture will continue to evolve in response to new or changing warfighter requirements and technology advancements. The JTRS is defined in terms of its hardware, software, networking, and security architecture. This paper addresses the Software Communications Architecture.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference. Proceedings (Cat.

Specification Language imparts integrity to the power system specification process and the resulting products. Building Codes are based on available high-end commercial products, and indicate their expected performance. The EPSS strategy is to provide the rational for the commercial power supply manufacturers to conform to these developing industry standards. Military power supply users will be able to confidently select needed resources from the commercial suppliers that conform to these EPSS standards.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

One application of this quality is to increase reuse by supporting product variations within a software product line. This is the focus of a Boeing effort to apply the product line software approach to the tactical aircraft mission processing domain. Another is to ease evolution during maintenance of a single product. The common goal is to facilitate anticipated variability between different software versions. Richly expressive languages like C++ and Ada95 offer many techniques to control and support variability, including inheritance, aggregation, generic programming, and conditional compilation. The breadth of alternatives available requires that developers understand the relative merit of each in different situations, This paper focuses not on the features themselves, but on guiding their optimal selection and application by discussing how well different language features support different variation types.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

This architecture has allowed the products to be constructed from a set of building blocks that may be mixed and matched to meet the needs of various space missions. Making use of COTS elements expands the debug and demonstration of these products. Future products, such as the RAD750(R) processor and its support chip, by utilizing the positive lessons learned, will be even more flexible and interchangeable than previous products and will provide cost effective solutions to space processing applications in the new millennium. This has only been possible through the use of open system interface standards.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

Starting from the analogy of visual clearances, EACAC investigates the possibility of giving electronic clearances in managed airspace. One of the issues of the study deals with the appropriate assistance scheme to be provided to the pilot, considering the proposed concept of limited delegation. An initial design work has been done, leading to the definition of key elements for cockpit displays: three different levels of assistance are identified, with different representations. All these options will be evaluated by pilots, first through a cockpit environment in a stand-alone mode (end 1999), and then using a cockpit simulator in a real-time simulation with controllers (mid 2000).","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

In areas, such as the northeastern region, where the beacon density is high, coverage overlaps of 15 or more radars may preclude aircraft flying over these zones from unequivocally determining the identity of the beacon they are communicating with. The purpose of this paper is to identify all areas within the CONUS presenting a potential overlap of 15 or more beacons and to assign each of them an identity number allowing a clear distinction from all surrounding overlapping radars. The database used in this study included all continental ASR-7, ASR-8 and ASR-9 beacons (Airport Surveillance Radar-Models 7,8 & 9) as well as ATCBI-6 (Air Traffic Control Beacon Interrogator-Model 6) and En route Mode S radars. Coverage was generated by dividing the CONUS into 3-nmi square cells and calculating the total number of radars reaching each of them. An algorithm was then developed to minimize the number of identity codes necessary for unambiguous differentiation. Solutions affecting radar characteristics such as relinking or range reduction were considered to further decrease this number.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

The problems associated with third order intermodulation distortion, IMD, generated by high powered FM broadcast transmitters has been studied several times and has resulted in an RTCA paper on the subject. A general improvement in the dynamic range of VHF navigation and communications receivers has reduced the susceptibility to IMD of newer receivers. However, the improvement of receiver IMD performance is accompanied by an increase in potential IMD generators. The described research will, first, assess the potential sources of IMD. Second, the amount of dynamic range required to reduce the IMD levels such that the IMD will pose no threat to safety of flight will be determined. Finally, a new silicon carbide technology will be integrated into communications and navigation receivers and tested.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.
