The MITRE Corporation Center for Advanced Aviation System Development (CAASD) is currently developing a prototype workstation to identify and validate the system requirements to enable Free Night. This effort will place a "Free Flight Workstation" in a working Air Route Traffic Control Center (ARTCC), with interfaces to radar surveillance and flight plan data. In addition, avionics intent information from several participating airline aircraft will be transmitted to the workstation via the ARINC Aircraft Communications Addressing and Reporting System (ACARS), and potentially other experimental data links. Initially, the workstation will provide supplemental conflict advisories to enroute controllers by integrating ground and airborne data sources in its algorithms. While the project is using a ground implementation, it is expected that airborne free flight enabling functions will require similar avionics intent information to be received via data link from other aircraft. This paper will describe the initial set of avionics intent information required from aircraft to perform conflict detection activities, and the architecture being used to obtain this information. Additional information which may potentially be used by follow-on ground or airborne functions will also be discussed.

This paper explores the generic structure of avionics beyond the Pave Pace system architecture. Projected constraints, opportunities and trends in several pervasive system building blocks which should be mature by this time frame are discussed and an example of the form this architecture might take is offered. In developing these projections, the author interviewed several technology experts in Industry and Government to help in forecasting the future of military avionics. General conclusions are: (1) costdriven sensor solutions will drive the avionics designs for most military avionics applications in order to meet demanding situation awareness goals, (2) the most pervasive and highest-leveraged building blocks used to build this advanced system will be commerciallyavailable data and signal processors along with advanced A/D converters and digital and RF photonics, (3) a continued increase in time sharing and physical integration at every level of the avionics architecture is projected, including multifunction EO and RF apertures, RF support electronics and a highly integrated digital system, (4) distributed high-speed photonic switches will permeate the architecture to achieve a unified interconnect network across RF, IF, data and signal processing modules built from families of printed wiring boards, (5) advances in packaging and microelectronics will result in the need for liquid immersion cooling and 3-dimensional stacking of RF, digital and photonic circuitry to support integrated apertures, digital receivers and data and signal processors to accomodate the needed speed and functional integration, (6) the digital boundary will move closer to the apertures to enable IF digital receivers for electronic warfare and radar applications (digital receivers up through L-band will have occurred during the Pave Pace era) and will extend the use of photonics beyond the digital arena to where photonically-controlled beam steering for phased arrays, RF signal distribution and hetereodyning will be possible. INTRODUCTION Predicting the characteristics of the next military avionics system beyond Pave Pace, which is not yet demonstrated, is obviously difficult because many assumptions must be made about the future direction of military priorities, budgetary constraints and the degree of success researchers will have in maturing several key technologies. This paper assumes the drive for low cost avionics will continue and that the 20 year system will evolve from the Pave Pace system introduced around the 200710 time frame. Therefore, one of the tasks at hand is to identify pervasive, highly-leveraged building block technologies, unavailable to the Pave Pace system that can further reduce avionics costs. For the 20 year design, these technologies should be in the early stages of prototype device development and significant funding interest must be shown by DoD departments such as the Advanced Research Projects Agency (ARPA).

In the past, our military systems have required technology not readily available in the industrial and commercial areas. This is no longer the case. Commercial products and practices offer the potential of reduced costs, lower risk and faster technology infusion. In order to achieve the potential benefits, our current methods of acquisition need change but it is important to review the background behind the institution of military standards and to assess their continued validity and to understand why. Also, before we rush to the conclusion that military specifications and standards are preferred for avionics over commercial products and practices, it is useful to review the specific requirements. In the past, in the absence of military specifications and standards, situations arose where items were developed using existing industrial and commercial products, processes and practices that at times led to catastrophic results or were inadequate to meet the threat. It is comforting that those who demand change show wisdom by asking that change be conducted with care and the impact understood. However, some use hyperbole in condemning the reliance on military specifications and standards and insist that their elimination is a good thing. In the domain of high performance aircraft avionics the potential for change is likely to be limited without an in-depth comprehension of the military environment, requirements and the capability of commercial products to satisfy them.

A flight demonstration was conducted to address airport surface movement area capacity issues by providing pilots with enhanced situational awareness information. The demonstration showed an integration of several technologies to government and industry representatives. These technologies consisted of an electronic moving map display in the cockpit, a Differential Global Positioning System (DGPS) receiver, a high speed VHF data link, an ASDE-3 radar, and the Airport Movement Area Safety System (AMASS). Aircraft identification was presented to an air traffic controller on AMASS. The onboard electronic map included the display of taxi routes, hold instructions, and clearances, which were sent to the aircraft via data link by the controller. The map also displayed the positions of other traffic and warning information, which were sent to the aircraft automatically from the ASDE-3/AMASS system. This paper describes the flight demonstration in detail, along with preliminary results.

This paper describes an experimental broadcast data link system architecture to identify and validate requirements for a broadcast data link and associated applications. Three key broadcast applications, including: Automatic Dependent SurveillanceBroadcast (ADS-B), Flight Information ServicesBroadcast (FIS-B), and Traffic Information ServiceBroadcast (TIS-B), are being investigated. The experimental system comprises three prototype components. The components are the Universal Access Transceiver (UAT), the Airborne Research Prototype (ARP), and the Ground Broadcast Server (GBS). Simplicity, affordability, and beneficial capabilities are the driving considerations for this work. The operational objectives are: to provide capabilities that are simple, affordable, and provide immediate benefit and utility to the aircraft operator; to enhance the user's ability to maintain separation from other aircraft; and to enable simplifications to the Air Traffic Management (Am) process.

Efforts to increase airport capacity include studies of aircraft systems that would enable simultaneous approaches to closely spaced parallel runways in Instrument Meteorological Conditions (IMC). The time-critical nature of a parallel approach results in key design issues for current and future collision avoidance systems. These issues are being studied in two ways. First, a part-task flight simulator study has examined the procedural and display issues inherent in such a time-critical task. Second, a prototype collision avoidance logic capable of generating this maneuver guidance has been designed using a recently developed methodology.

This paper presents the results of tests using Cardion's Cooperative Area Precision Tracking System (CAPTS), The basic theory of operation of a multilateration system is explained. The ability of CAPTS to provide positive aircraft identity in order to put "tags" on ASDE radar displays is proved through presentation of test data. Data showing both theoretical and measured positional accuracy with test results showing the probability of correctly identifying targets is included. Test data is derived from recent demonstrations conducted at the FAATC in Atlantic City, NJ and the tests conducted at Hartsfield International Airport in Atlanta GA.

In his June 29, 1994 memo, Secretary of Defense Perry challenged Dod agencies (and Industry) to move to greater use of performance and commercial specifications and standards, and shelved a host of military standards, including those related to software. After an intense lobbying effort by the Dod and Industry, the DoD approved the use of MIL-STD-498 for two years; assuming, a non-Government software standard would replace it in that time frame. The U.S. Navy and Air Force have issued waivers permitting MIL-STD-498 to be invoked on contracts. The Institute of Electrical and Electronics Engineers (IEEE) and the Electronic Industries Association (EIA) are working together to create a nonGovernment software standard. Because MIL-STD498 is new and being applied on selected projects, there is no published information on its practical use. This paper briefly: (1) highlights MIL-STD-498 as the new way of developing software; (2) examines MIL-STD-498's application on a governmentsponsored real-time guidance, navigation, and control project underway at the Draper Laboratory; and (3) reviews the effort to create non-Government software Standards.

Aircraft surveillance in the Gulf of Mexico can be substantially improved at relatively low cost with GPS-Squitter, a form of Automatic Dependent Surveillance Broadcast(ADS-B), with GPS-Squitter, aircraft in the Gulf would use Mode S transponders to automatically broadcast (i.e., squitter) their position (latitude, longitude, and barometric altitude) and identification. An aircraft would determine its position from an onboard positioning system such as GPS (Global Positioning System). To demonstrate the feasibility of GPS-Squitter low-altitude surveillance in the Gulf of Mexico, MIT Lincoln Laboratory, in a cooperative effort with the FAA (Federal Aviation Administration) and industry, conducted a series of tests in the Gulf during November and December 1994. For the tests, three GPS-Squitter ground stations were deployed in the Gulf-two on oil platforms and a third at the Petroleum Helicopters, Inc. (PHI) heliport in Morgan City, Louisiana. The ground stations were used to track three GPS-Squitter-equipped aircraft (two Bell 206 helicopters and Cessna 421); live traffic displays were available in Morgan City, New Orleans, and Houston. This paper describes the configuration of the test vehicles and ground stations. Surveillance performance results are also included for each of the test vehicles.
