Award Data

Virtual Globe (VG) systems such as Google Earth, NASA World Winds and Microsoft Virtual Earth provide captivating animated 3D visualizations and support user queries for information at a point. NASA MSFC's VG-based Real Time Mission Monitor (RTMM) enhances management and tracking of field experiment missions. The National Weather Service's RIDGE service uses VG to disseminate radar and support dec ...

In typical, multi-organizational networking environments, it is difficult to define and maintain a uniform authentication scheme that provides users with easy access to required information while maintaining the security and integrity of the underlying information. This proposal offers a unique and innovative architecture for doing so through the utilization of a Proxy Service Listener (PSL) and ...

In this NASA Phase I STTR effort, the feasibility of fabricating isolated ridge waveguides in 5% magnesium-doped lithium niobate (5% MgO:LN) will be established. Ridge waveguides in MgO:LN will significantly improve the power handling and conversion efficiency, increase photonic component integration, and be well suited to space based applications. The key innovation in this effort is to combine ...

This SBIR Phase I effort proposes to establish the feasibility of developing a compact, high performance laser source for integration into the next generation seed laser system for high stability, multi-wavelength lidar applications such as NASA Langley's HSRL program. Combination of the high performance laser source together with ADVR's integrated Planar Lightwave Circuit (PLC) technology will p ...

This Small Business Innovation Research Phase I project will develop a compact, rugged, rapidly and widely tunable laser based on a quantum cascade diode laser at mid-infrared wavelengths. The key innovation in this effort is the use of an engineered electro-optic tuning element in an external cavity laser to provide control of the laser wavelength through an applied voltage. AdvR has previously ...

The objective of this proposal is to design, construct and test a high-frequency-response air-data probe, the Fast Response Atmospheric Turbulence probe (FRAT probe) that will be able to operate in harsh and humid atmospheric environments. Both requirements, high-frequency response and resistance to water spray can be accommodated by mounting the pressure sensors flush with the probe surface. We w ...

Wake vortices are a critical constraint to aircraft separation and therefore airportal throughput, which is already at or near capacity at many major airports in the NAS. Improvements to current methods of spacing aircraft could significantly increase airportal capacity, but there is currently limited awareness of wake encounters and information with which to assess spacing in real-time or to des ...

FAA predicts that air traffic will double or even triple by 2025 and unless solutions that enable improvements in the use of airspace can be developed and implemented, significant airspace congestion will occur. Advancements in aircraft capabilities via new technologies can enable aircraft to operate more efficiently in the NAS and to operate safely in areas previously restricted. AeroTech propo ...

The objective of this project is to demonstrate intelligent health and maintenance status determination and predictive fault diagnosis techniques for NASA rocket engines under online and offline conditions from either on-board or maintenance, test and analytic data. AGNC proposes a Health and Maintenance Status Determination and Predictive Fault Diagnosis System (HMSD/PFDS). The fuzzy qualitative ...

The on-ground and Distributed Rocket Engine Testing Health Monitoring System (DiRETHMS) provides a system architecture and software tools for performing diagnostics and prognostics for supporting NASA's Integrated System Health Management (ISHM) capability for rocket engine testing and ground operations. DiRETHMS architecture consists of a hierarchical, modular, scalable, and flexible system struc ...
