The ability to overcome these challenges is constrained by such factors as shrinking budgets, limited computational capacity and diminished manufacturing sources (DMS) effects that impact both hardware and software options. Wholesale redevelopment is often cost prohibitive, particularly since large portions of embedded applications continue to fulfill mission requirements. Solutions must preserve prior investments while providing efficient pathways for continued technology refresh. The Air Force Research Laboratory Information Directorate, Lockheed Martin Tactical Aircraft Systems (LMTAS), and Xinotech, Inc. Are creating a technology solution for affordable modernization of legacy system software. The Embedded Information System Re-engineering (EISR) project is developing an automation-assisted JOVIAL-to-C re-engineering capability that permits simultaneous modernization of both the structure and source language of legacy embedded applications. Engineers will be able to apply the proven labor-saving visualization and analysis features of modern CASE tools to legacy JOVIAL applications. EISR will thus allow the DoD to recapture previous investments in proven legacy algorithms and mission capabilities while permitting the full exploitation of COTS economies of scale. This paper describes in brief the goals and objectives of the EISR project, and provides the current status of the EISR capability.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

In O-NAV, no one sub-component bears the burden of the problem. In other words, it is not expected that algorithms alone will solve the computer vision problem. If we choose effective sensing that inherently performs some level of scene discrimination at the phenomenology level, algorithms will be handed a partially analyzed scene before they ever encounter the raw image data. The algorithms have been designed to exploit an optimized processing hardware infrastructure, to maximize computation for the \"real-time\" application of autonomous robot navigation.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

This MAC protocol incorporates priority queuing, slotted ALOHA, and polling by the ground station to handle channel contention and to achieve the speedy delivery of time critical ATC messages. This paper provides an overview of the VDL Mode 3 subnet simulation models in Optimized Network Engineering Tools (OPNET). Four different subnet models are available for the simulation of different system configurations, namely, 2V2D, 3V1D, 4D, and 3T. The usefulness of these simulation models is demonstrated by their capability in simulating a wide range of scenarios and protocol alternatives in dealing with various configurations, load factors, and protocol parameter settings.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

To meet these broad requirements the APL launched an internal research and development initiative to make significant advancements in electronic packaging technology. Among many miniaturization techniques available for design and development, chip-on-board (COB) based on laminated multichip module technology was selected. The technology utilizes a straightforward design concept, that has been simplified through careful review and testing. In the COB technology, both bare dies and conventional packaged devices are mounted on the same substrate with a special coating to protect the circuits from handling, ground testing, and in-orbit environments. The flexibility of COB packaging techniques helps resolving parts shortage, and last-minute part change problems. This paper summarizes the packaging design, development, and fabrication of two miniaturized space systems-the Command and Data Handling In Your Palm (C&DH IYP) and the Miniaturized Scientific Imager (MSI)-using COB technology. The C&DH IYP is a modular system consisting of multiple individual slices that can implement anything from a standalone Instrument Processor, to a Command and Data Handling system, or the entire electronics needed by a spacecraft. The MSI is a narrow-field-of-view visible imager design with a reflective telescope, a single filter, and a charged-couple device (CCD) detector. We demonstrate that mass and volume reduction of a factor of 10 can be achieved with low-cost COB packaging technology.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

Among the many applications is the use of GPS Receivers (GPSR) onboard space vehicles. With the large quantity of receivers available, finding one suitable for space applications is very difficult. This paper captures some of the \"lessons learned\" resulting from development efforts within Honeywell Commercial Systems Operation to integrate GPS technology into space borne navigation systems. The intent is to highlight a few of the major issues and differences between a GPSR for space, and the inexpensive terrestrial based receivers. Operating conditions including vehicle dynamics and environmental factors require a thorough understanding. Despite the difficult design issues, there remains considerable benefit in using GPS for spacecraft.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

Today, the standard's high-speed deterministic communication, low cost, and guaranteed bandwidth are sparking some interest in other markets. Increasingly, IEEE-1394 is being adopted for interconnecting real-time computer systems. The technology offers many obvious benefits for real-time applications such as simulation systems, manufacturing automation, and industrial control.
