The problem addressed in this effort is to automatically learn historical ephemeris space catalog time, position, and velocity entity track update error uncertainties (i.e., without track error covariances) and to automatically (e.g., without expert event labeling) produce: – unmodeled non-gravitational space catalog update flags – abnormal unmodeled catalog update flags with abnorma ...

ABSTRACT: In Phase II, we will fabricate a SQUID array antenna. We will develop cryopackaging and control electronics for these devices. We integrate the device onto a cryocooler and build a laboratory prototype. We will then have all of the building blocks to build a fieldable prototype in Phase III. BENEFIT: Military Application: Microwave Communication Systems for ISR. Commercial Application ...

The objective of this project is to develop a practical finite element-based simulation of spin-pit tests of disks. The performance of disks in spin-pit tests critically depends on localized effects, such as residual stresses, dislocations, and microstructure gradients. Therefore, a two-scale modeling approach is adopted. At the global-scale, the disk is represented by means of finite elements wit ...

Two-dimensional (2D) visualization techniques have limit capacity to achieve understanding of full dimensionality of the battlefield. Rewritable 3D holographic storage is promising for updatable 3D display applications. In Phase I, New Span Opto-Technology has demonstrated novel concepts of both holographic recording technique and recording material system without the use of high voltage. We have ...

ABSTRACT: In this STTR effort a small business company Obalon LLC is teaming up with industry leader Aerospace Corporation for development of novel photostructural glass ceramic composition (PhotoCon) with capability of laser induced 3D conductor patterning inside the bulk material. The development fully utilizes available infrastructure and team's expertise for commercial glass ceramics pro ...

Over the past 2 years, Roccor has successfully qualified and delivered High Strain Composite (HSC) products for space-flight customers including, 1) RF-Furlable boom, 2) a furlable-antenna system; and is currently qualifying HSC products for space-flight customers including 3) an FCC certified deorbit device, and 4) a solar array deployment system. Three of these missions will be launched in 2018. ...

ABSTRACT: Optical refrigeration is currently the only demonstrated all-solid-state cryocooling technology. Optical cryocoolers are devices that use laser light to cool small crystal or glass cooling elements. The cooling element absorbs the laser light and reradiates it at higher energy, an example of anti-Stokes fluorescence. The difference between the energy of the outgoing and incoming light c ...

Multi-processor computing systems are growing in capacity and usage. They encompass multiple, distributed implementations as well as heterogeneous, embedded computing architectures. The processing density enabled by such approaches holds promise for unmanned combat air vehicles (UCAVs) with their plethora of mission sensors and command and control processing requirements. However, the software ...

Carbon nanotubes (CNTs) have great potential for high performance RF applications. Theoretical study has shown that the electrical current in a CNT field effect transistor (CFET) is intrinsically linear. Today, linearity is the underlying limitation in increasing the data transport densities of wireless networks. The complex modulation protocols used to achieve higher data rates requires linear am ...
