COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

THERE EXISTS A NEED FOR FIELD EVALUATION TECHNIQUES ON DAM- AGED RAIROAD TANK CARS, A LARGE PROPORTION OF WHICH ARE OF INSULATED DESIGN CONSISTING OF AN OUTER SHELL, AN INSULA- TION SPACE, AND AN INNER LINER. THESE CARS ARE USED TO HAULMANY POTENTIALLY HAZARDOUS MATERIALS AND CHEMICALS, AND THEREFORE, MUST BE CAREFULLY ASSESSED IN THE EVENT THAT THEYARE DAMAGED. A MAJOR DIFFICULTY ARISES IN ATTEMP ...

A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THA ...

Passenger safety concerns have prompted the FAA to elicit energy-sensitive neutron detectors which do not rely on the time-of-flight method and are suitable for use in explosive detection systems. Invocon, Inc. proposes to design an inspection system consisting of an energy source and a detector. Designated FERET sytem, (Field Energy Recoid Emission Technology), it would detect substances identi ...

For more than three decades, transportation planners have relied on survey data collected specifically for the development of travel forecasting models, which are expensive to collect and maintain on an ongoing basis. There is a plethora of data collected for other reasons that could potentially support transportation planning which is becoming more accessible through technological advances. Use ...

AN IBM PC-COMPATIBLE AIR TRAFFIC CONTROL SIMULATOR WITH VOICE I/O, AN EXTENSIVE DATABASE OF GEOGRAPHICAL FIXES, AND CONFLICT RESOLUTION VIA AN EXPERT SYSTEM IS PROPOSED. THIS SIMULATOR WILL BE DESIGNED TO FACILITATE AIRSPACE DESIGN ANDPROCEDURE DEVELOPMENT. CAPABLE OF DISPLAYING A REALTIME RADARSCOPE PICTURE OF ANY GEOGRAPHICAL AREA, ITS SECTORS MAYBE CREATED VIA A SIMPLE USER INTERFACE BY FIELD P ...
