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 ...

THE PROPOSED PROJECT WILL DETERMINE THE FEASIBILITY OF DEVELOPING A LOW-COST, INTEGRATED, BAR CODE TECHNOLOGY BASED INFORMATION SYSTEM WHICH CAN BE INSTALLED ON TRANSIT VEHICLES. THE PROJECT WILL RESULT IN A SURVEY BASED APPLICATION FEATURE REQUIREMENTS DEFINITION, A PHYSICALLY INTEGRATED HARDWARE AND OPERATING SYSTEM PLATFORM SPECIFICATION TO SUPPORT THE APPLICATIONS, A DETAILED APPLICATIONS SOFT ...

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 ...

A new approach to generating atomic hydrogen (and possibly N and O) will give atomic fluxes of 10(-19) atoms/cm(-2) over a three inch wafer positioned three inches in front of the source. Scalt up to larger areas may be possible in phase II. We will examine the use of this source as an alternative to hot filament assisted generation of atomic H for diamond thin film growth. Use of the source for M ...

Ionwerks has begun an internally funded project to design and manufacture an MBE growth chamber specifically designed and optimized for wide bandgap nitrides (compatible with Si/Ge growth also). This chamber will include two proprietary growth techniques which we have found to be crucial for formation of cBN thin films. Design and construction of this chamber is underway. We will use this equipmen ...

We propose to develop a new type of optical filter with these properties that is constructed using thin, alternating layers of dispersive and non-dispersive media. Like the classic interference filter, this device operates through the selective constructive and destructive interference of the optical waves. However, the use of dispersive media in the filter allows enhanced narrowing of the transmi ...

Oxide coatings previously developed to protect polyimide and carbon/carbon composites in low earth orbit are brittle and crack upon flexing. Adding small amounts of polytetrafluoroethylene (PTFE) increases coating flexibility but reduces atomic oxygen (AO) resistance and mechanicall durability. Coatings developed in this project will use inorganics with potentially greater flexibility (such as she ...

THE FEDERAL AVIATION ADMINISTRATION (FAA) HAS LONG BEEN INTERESTED IN THE MITIGATION OF HAZARDS TO LIFE SAFETY FROM FIRE ONBOARD COMMERCIAL AIRCRAFT. THE DEVELOPMENT OF SUPERIOR FIRE RETARDANT (FR) ADDITIVES FOR POLYMERIC MATERIALS, WHICH MIGHT BE USED IN THE INTERIORS OF AIRCRAFT, IS ONE WAY TO ADDRESS THIS PROBLEM. THIS PROPOSED PROGRAM WILL EXAMINE THE EFFICACY OF CURRENTLY AVAILABLE FIRE RETAR ...
