"A significant problem for stakeholders in large satellite systems is the difficulty of getting data about these systems when it counts the most - in orbit and during critical anomalous situations. Near-field diagnostic tools - including visual andinfrared images and close-range radio frequency measurements - are now becoming feasible to examine performance, anomalies, and failures on orbit.AeroA ...

"In this work, we propose to capitalize on our experience with synthetic jet actuation, low order system modeling, and control in order to develop an integrated approach to hingeless flow control. We first propose to develop a new, hybrid, synthetic jetactuator that will be capable, via real-time actuator parameter control, of both separation manipulation (reduction, elimination or promotion) and ...

"The Air Force is pursuing aircraft and satellite-based high power laser systems to engage and destroy missiles at long ranges (hundreds to thousands of kilometers). A precision inertial reference unit (IRU) is critical to successful operation of longrange, high power laser systems for missile defense. The IRU enables the system to accurately point the payload telescope and attached tracking sen ...

"Athena Technologies, Incorporated (Athena) and Carnegie Mellon University Robotics Institute (CMU) propose to exploit use of visual odometry capabilities via real-time computer vision, to augment inertial sensors, 3D magnetometer and GPS to determine thevelocity, position and attitude of a missile or unmanned air vehicle. The proposed architecture exploits the excellent performance Athena has dem ...

"The objective of this Phase I proposal is evaluate battlespace geolocation correlation opportunities that may be obtained by fusing measurements from Ground Moving Target Indicator (GMTI) and Signals Intelligence (SIGINT) collections. These opportunitiesinclude (1) improving geolocation accuracy at the processing level using individual sensor measurements from dissimilar collection systems and (2 ...

"We propose to develop a Global Positioning Satellite/Inertial Measurement Unit(GPS/IMU) integrity monitor using techniques that can be implemented in parallel. The first technique takes advantage of the GPS link modulation, namely spreadspectrum coding and bi-phase shift keying. A multiple step procedure will allow spectrum monitoring for downlink integrity, increased background noise, jamming a ...

"Microdischarge based chemical sensing is a novel detection scheme that relies on extremely sensitive emission spectroscopy, without the need for expensive plasma sources and vacuum systems required in large scale plasmas. This technique provesparticularly powerful for metals detection due to strong emission spectra from metals in a discharge. Additionally, the sensors presented are small, rugge ...

"Microdischarge based chemical sensing is a novel detection scheme that relies on extremely sensitive emission spectroscopy, without the need for expensive plasma sources and vacuum systems required in large scale plasmas. This technique has a broad rangeof capabilities due to its universal detection capabilities for small molecules. Additionally, these sensors are small, rugged, and require very ...

"High-accuracy electromagnetic simulation method is traditionally very inefficient.Recently however, MLFMA (multilevel fast multipole algorithm) has demonstrated theability to solve scattering problems accurately up to X band (10 million unknowns).Although orders of magnitude faster than traditional accurate methods, in thehigh-frequency regime such as X band, these fast methods are still not as f ...

"Proposed here is an effort to develop a generative, knowledge-based instructional development and delivery system, Jenny, for simulation-based training. Courseware development with Jenny involves (a) populating a knowledge base representing the structureof subject-matter knowledge and (b) creating simulation-based and other instructional materials that are associated with the knowledge base. At d ...
