Electrostatic thrusters are the likely choice for station keeping of the new generation of small communication satellites. Xenon is the fuel of choice for these thrusters because of its high mass and low ionization potential. Existing worldwide xenon production will not permit fueling of more than a small fraction of the projected satellite population unless significant price increase of Xe is rea ...

In this Phase I STTR, Sterling Semiconductor--in cooperation with the University of Colorado at Boulder--will develop novel heterojunction bipolar transistor (HBT) semiconductor devices for microwave applications. Specifically, the team will develop I gallium nitride (GaN)/silicon carbide (SIC) N-p-n HBTs, consisting of a gallium nitride emitter on a p-type silicon carbide base and an e-type silic ...

With the rapid strides in various avionics-related technologies, the need for advanced simulators will increase. Anti-jam receiver development and future improvements in PNT are critically dependent on the availability of advanced simulators. The needs include: flexible, accurate, adaptable, programmable, user-friendly, hardware in the loop operation, precise wavefront simulation, high dynamics, e ...

MDA Model and Simulation capabilities include Core Truth models capable of simulating all physics governing missile detection, tracking and intercept events. A key component of the simulation tools is an accurate and fast atmospheric radiation model to describe the target signal propagation through the atmosphere to the sensor. Such a model should be designed to readily interface with existing sc ...

Higher resolution optical sensors are driving requirements for highly detailed representations of natural background surfaces and man-made objects for real-time scene generators used in development of Ballistic Missile Defense Systems (BMDS). New methods are critically needed to represent such structures that are computationally efficient enough for scene generators to support the high frame rates ...

Hydropower is now increasingly operated outside of original design conditions due to changing water availability and environmental induced operating parameters. Fifty percent of operational hydroelectric dams in the United States are 50 years or older and nearly all were designed to operate steadily as a primary base load resource. Compounding these issues is the increasing prevalence of intermitt ...

The primary objectives of this Phase II project are to 1) validate performance of the prototype resequencing pathogen microarray application for detection and identification of selected food-borne pathogens, including varieties of viruses, bacteria and eukaryotic agents; 2) iterate and port the prototype application to a more practical, "market-friendly" product form factor that requires less expe ...

Detecting, localizing, and intercepting one or more missiles during ascent phase presents a daunting theoretical and practical challenge. Scientific Systems Company, Inc. of Woburn, MA, and its subcontractor, Lockheed Martin, propose a foundational, control-theoretic approach to such problems. It is based on the idea of mathematically modeling a multiplatform-multisensor-multitarget system as SING ...

Detecting, localizing, identifying, tracking, and intercepting multiple and dispersed missiles aimed at multiple and dispersed defended areas, presents a daunting theoretical and practical challenge. The Scientific Systems Company, Inc. team proposes a foundational, information-theoretic and controltheoretic approach. It is based on mathematically modeling a multiplatform-multisensor-multitarget s ...

SI2 Technologies, Inc. (SI2) proposes to design and develop a multifunction conformal antenna system for UHF Flight Termination System (FTS), L-band Global Positioning System (GPS), and S-band Telemetry applications for the SM-3 family of missiles and other platforms. To reduce the depth of protrusion, axial length, and weight of the multifunction antenna while maintaining wide bandwidth and high ...
