A nondestructive evaluation method is proposed for imaging in-roadway sensors, anticipated to allow them to be located and evaluated in-situ. The techniques uses innovative step frequency GPR hardware together with new data collection and data processing methods to provide high-resolution images of in-roadway sensor features. Recent work by the proposed research team has already demonstrated im ...

This proposal addresses the design and development of dynamically controlled protein crystal growth payloads for Space Station application. The Space Station will afford the protein crystal growth community the unprecedented opportunity to grow crystals in a microgravity environment for extended periods of time and then retrieve them. This will add a new dimension to determining the structures of ...

The primary objective of the SBIR effort proposed herein is to develop the hardware and software prototype of a novel high-resolution volumetric three-dimensional (3D) display system that is suitable for visualizing various types of 3D data collected by satellite sensors. The proposed volumetric 3D display technique has a 360 degree look-around group viewing capability and allows a group of viewer ...

The key innovation of this proposal is implementation of a Time Modulated Ultra-wideband (TM-UWB) radio to implement a bi-directional astronaut to spacecraft wireless link. Our innovation will also provide a real-time reading of the position of the astronaut, and with two small conformal antennas on the astronaut, it will provide the astronaut orientation and position in real-time. Within the last ...

The key innovation in this effort is the development of a decision support tool for distributed air-ground scheduling sequencing, spacing and merging of aircraft in the terminal airspace, and the development of modeling and simulation testbed that will enable the evaluation of NAS wide impacts of technologies related to Airspace Super Dense Operations in the Terminal Airspace. The SBIR will prim ...

As space missions become more complex and as mission demands increase, robots, human-robot mixed initiative teams and software autonomy applications are needed to provide increasing levels of support to the mission and to Astronauts. Whatever the task, robot teams will need to interact with Astronauts and possibly Mission Control. There is a need for cooperation and communication among all autonom ...

Building on recent advances in formal agent specification, protocol composition, model composers, and visualization capabilities provided by development environments such as eclipse, the key innovation in this effort is the development of an agent model composition toolkit that will enable NASA ACES users to design and compose agents, activities, and models to meet specific design requirements. F ...

The goal of this Phase II project is to deliver an integrated L-band transmit/receive (T/R) module which will be fabricated from a GaAs-based combined HBT/PHEMT epistructure. The T/R module will consist of a power amplifier, a low noise amplifier, and two switches. The performance goal for the low noise amplifier is 30 dB gain with a less than 1.0 dB noise figure. The performance goal for the p ...

The area of innovation of this proposal is in cost. We propose to attempt the design of an extremely low-cost spacecraft control and pointing system with, nontheless, high quality pointing accuracy and stability perhaps as good as a few arcseconds. Further we will attempt to design this GN&C system in a way that can be easily adopted by technical communities with small amounts of aerospace infrast ...

The objective of the project is the development of an open architecture, computational toolbox for design and implementation of diagnostic and prognostic algorithms for aircraft electrical power systems. The management of typical failure modes of the electrical system can have substantial returns in the overall availability, safety and operating cost of aircraft. We propose several innovative tech ...
