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 ...

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 ...

Polymer Bridge Systems, with over 8 years of research composite bridges, found that success hinges on being dollar-for-dollar cost competitive with steel and concrete. We founded the four "golden rules" that are required: the bridge must be: 1) factory build; 2) road transportable; 3) installed in 1 eight-hour day; and 4) be cost-competitive on an installed cost basis. This bridge will be buil ...
