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 ...

CURRENTLY COMMERCIAL SPACE-LAUNCH FREQUENCY REQUIREMENTS ARE MET IN THE 2200- TO 2300-MHZ BAND. NEW FREQUENCY ALLOCATIONS MAY LIMIT FREQUENCIES FOR COMMERCIAL SAFE AND RELIABLE COMMERCIAL SPACE-LAUNCH OPERATIONS TO THREE CHANNELS IN THE 2360- TO 2390-MHZ BAND. THIS RESEARCH WILL ASSESS WHETHER THIS ALLOCATION IS SUFFICIENT TO ENSURE CONTINUED SAFE AND RELIABLE COMMERCIAL SPACE-LAUNCH OPERATIONS. D ...

Digital Wave Corporation proposed to develop a novel nondestructive testing (NDT) system for high speed acquisition and analysis of wide band acoustic emission (AE) waveforms. The system will provide the capability to detect, identify and locate crack growth in loaded steel structures. This system will incorporate the new high fidelity sensor developed by the Federal Highway Administration and a ...

INTEGRATED DAMAGE CONTROL SYSTEMS (IDCS) HAVE THE POTENTIAL TO IMPROVE MONITORING, DECISION-MAKING, AND RESPONSE TO SHIPBOARD EMERGENCIES. ULTIMATELY, IMPLIMENTATION OF THESE SYSTEMS MAY REDUCE MANPOWER. THE TECHNICAL OBJECTIVE OF PHASE I WILL BE TO PROVIDE THE USCG WITH SEVERAL DESIGN CONCEPTS FOR INSTALLING IDCS ON USCG SHIPS. THIS WILL INCLUDE ALTERNATIVES FOR HARDWARE AND SOFTWARE AS A FUNCTIO ...

Not Available The proposed effort will investigate the feasibility of both improving identification performance of high-range-resolution (HRR) Non-Cooperative Target Identification (NCTI) algorithmic systems and greatly reducing the time necessary to develop them. The effort will focus on developing a feature-based approach that will rely on analysis and characterization to determine those featur ...

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 ...
