On-orbit servicing and logistics support spacecraft could greatly enhance the flexibility and functionality of many future MDA space assets by providing, refueling, diagnostic, or component replacement services. AeroAstro proposes to take the first stepstowards achieving an affordable on-orbit servicing and logistics capability by developing a scaleable, modular spacecraft architecture and applyi ...

Barron Associates, Inc. (BAI) proposes an aggressive Phase I effort to develop novel adaptive, integrated guidance, control, and estimation algorithms for ballistic-missile interceptors with stringent hit-to-kill requirements. The approach combines recentadvances in nonlinear control (backstepping) and estimation methods, and leverages on-line neural network technology for rapid adaptation and ro ...

The ideal prognostic system would be generic, requiring no domain-specific knowledge for its application. The prognostic system must also perform across all operating regimes without generating an excessive number of false alarms, and must successfullydiagnose problems. The semi-empirical technique proposed herein by Barron Associates, Inc. and its academic partners at Princeton University takes a ...

We propose a software package that combines recent advances in several pattern recognition techniques, including neural networks, multivariate statistics and model-based reasoning. Results from these prognostics will be combined into a single probabilityof failure for the modeled component or subsystem of the ABL, which would be output to a simple graphical user interface (GUI). The preliminary so ...

The Be-B binary alloy system has a eutectic at 10 at. % boron, where the singular melting point is at 1120 oC. This value is some 169 degrees below the normal melting point of beryllium. The intent of the present STTR proposal is to use this circumstanceto develop a

We propose to design and develop an advanced GPS/INS integrated system for anti-jam and high dynamics conditions. Integration between GPS and INS will be performed in a federated sense using ultra-tight coupling. CRS has developed a novel GPS developmentsystem consisting of integrated software tools and hardware modules. These tools allow simulation and real-time implementation in a single step ...

This Small Business Innovation Research Phase 1 project will develop novel devices capable of actively cooling high power electronics using ceramic micro-channel evaporatos. Microelectronics with demanding thermal management characteristics are usedpredominantly as microprocessors and power electronics (HDTV modules, higher power logic and power transmit/receive). The number of microprocessors so ...

We propose to implement an array of machine learning algorithms thatcan synthesize failure-prediction monitors with a minimum of human domain knowledge.Such a condition-monitor analyzes behavior data generated by computercontrolled devices --- data that can come from sensors on mechanicalequipment as well as sensors within the control software --- andidentifies evidence of impending malfunctions. ...

In the future Ballistic Missile Defense system, it will be necessary to coordinate the operations of many geographically dispersed system components to create an architecture with the best chance for defeating the threat. Though challenging, it is desiredthat this architecture be implemented in a distributed manner to avoid the need for a centralized controller to which all sensors transmit all o ...

The lithium x-ray lens successfully demonstrated in Phase I will be improved until its performance is at the theoretically expected level. The lens will be implementedon the APS and the NSLS synchrotrons, Jefferson Lab, and the Stanford/LLNL LCLS. Besides the alligator lens of Phase I we will also produce lenses that focus with a parabolic profiles, in one and two dimensions. We will determine the ...
