The AquaScan, a miniaturized UV/VIS/NIR hyperspectral imager will be built for deployment on a UAV or small manned aircraft for ocean coastal remote sensing applications. The hyperspectral system includes a data acquisition system with remote operation capability proving a real-time waterfall display of the hyperspectral scans. OKSI teamed with Scripps Institution of Oceanography to define and d ...

The goal of this project is to develop, demonstrate, and deliver to NASA an innovative, portable, and power efficient Remote UV Fluorescence Lifetime Spectrometer (RUVPhaseTM) for the in-situ robotic or manned crew planetary scientific exploration and investigation of surface and subsurface geophysical terrain. The RUVPhaseTMsystem is based on the integration of ROI's le ...

In Phase II, XNAV performance will be enhanced through the development of single photon processing algorithms, which utilize all available photon time data to improve the accuracy of XNAV. A detailed model of the XNAV system, including single photon techniques will be implemented in Orbit Determination Toolbox (ODTBX), increasing its functionality and providing a valuable mission design tool. O ...

To enhance aviation safety, numerous adaptive control techniques have been developed to maintain aircraft stability and performance in the presence of failures or damage. Flight evaluations of various adaptive controllers conducted by NASA and others have shown great promise. In some cases unfavorable pilot-vehicle interactions including pilot-induced oscillations have occurred. Susceptibility to ...

The original Sublimator Driven Coldplate (SDC) design sought to provide significant mass savings over a traditional pumped fluid loop by combining the functions of a cold plate and a sublimator and eliminating the fluid loop (Leimkuehler, et. al., "Design of a Sublimator Driven Coldplate Development Unit," 2008-01-2169). The target application was to provide heat rejection for the ascent module of ...

Adverse aeroservoelastic interaction is a problem on aircraft of all types causing repeated loading, enhanced fatigue, undesirable oscillations and catastrophic flutter. Traditionally, to suppress adverse aeroservoelastic interaction, notch and/or roll off filters are used in the primary flight control system architecture. This solution has pitfalls; rigid body performance is degraded due to resul ...

We have developed a low dropout (LDO) regulator using a patented MESFET transistor technology that can be manufactured in commercial CMOS foundries with no changes to the process flow. The regulator is stable under all load conditions without an external compensation capacitor, thereby reducing the mass/volume of the power management system and increasing reliability. The MESFET-based LDO componen ...

This Phase I Small Business Innovation Research proposal will develop porous dielectrics as a low-cost, large-area detector for high spatial resolution x-ray detection. An alternative to microchannel plates, porous dielectric electron amplifiers are formed by a thin layer, generally less than 1 mm, of a low density dielectric. The microscopic pores formed in such material, provide a natural, but m ...

For propulsion related applications, materials must be able to demonstrate excellent ablation and oxidation resistance at temperature approaching 3500?C, adequate load bearing capabilities, non-catastrophic failure modes, and ability to withstand transient thermal shock. Advanced Ceramics Research, Inc. (ACR) has developed low cost, flexible-manufacturing processes for Zr & Hf-based carbon fiber r ...
