A 3-DIMENSIONAL ATTITUDE SENSOR WHICH USES GPS CARRIER PHASEINTERFEROMETRY IS PROPOSED FOR ANALYSIS AND CONCEPT TESTING IN PHASE I, AND PROTOTYPING IN PHASE II. THE RESULTING SENSOR WILL BE ACCURATE AT ANY LATITUDE. ADROIT SYSTEMS PROPOSES TO ENHANCE ITS SUCCESSFUL 2-DIMENSIONAL, STATIC GPSATTITUDE DETERMINING SYSTEM (ADS) SO THAT IT WILL OPERATE UNDER DYNAMIC CONDITIONS WHILE MEASURING 3-DIMENSIO ...

AN INNOVATIVE OBSTACLE DETECTION SYSTEM BASED ON A RAIL-GUIDED PROPELLER-DRIVEN POD CONTAINING A MICROWAVE RADAR SENSOR IS PROPOSED. THE SENSOR POD WILL TRAVEL A FEW MILES AHEAD OF THE HIGH SPEED TRAIN OR MAGLEV VEHICLE, DETECT POTENTIAL OBSTACLES, AND ENACT AN APPROPRIATE WARNING OR AVOIDANCE PROCEDURE. THE PROPOSED OBSTACLE DETECTION SYSTEM HAS MANY HIGHLY DESIRABLE FEATURES INCLUDING: A VERY LO ...

THE ULTIMATE OBJECTIVE OF THIS RESEARCH EFFORT IS THE DEVELOPMENT OF A SHIP MANEUVERING SIMULATION SOFTWARE PACKAGE FOR SHIPBOARD USE IN MANEUVERING ASSESSMENT, PASSAGE PLANNING AND TRAINING. THE SOFTWARE MUST OPERATE IN A STAND ALONE MODE AND/OR INTEGRATED WITH THE SHIP'S NAVIGATION AND CONTROL SYSTEM. THE PHASE 1 EFFORT INCLUDES THE INITIAL DETERMINATION OF THE REQUIREMENTS FOR THIS SOFTWARE PAC ...

The ultimate purpose of the proposed R&D is to develop and demonstrate an innovative software development environment which supports the engineering, analysis, development, test, maintenance, and reuse of software for embedded, heterogeneous, real-time systems. The proposed approach is innovative in two respects: (1) it is based on the integration of two best-of-breed environments, ObjecTime/ROOM ...

Development of reliable (Q-) switching and isolation materials is being sought for near-to-mid infrared lasers for safety, extended life and fiber optic communication. The voltage or E-field controlled (Q-) switching materials such as Pockels cells and liquid Kerr cells are not reliable for long term operation in tactica applications due to crystal surface (e.g., KDP, ADP) degradation by moisture ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

Astralux will develop IV-II-VI compound semiconductors by synthesizing compounds and characterizing their properties as a function of the deposition parameters. The material will be a combination of lattice-matched semiconductors that will be generated as alloys and superlattices. Electronic and optical properties will vary by adjusting the composition. The II-VI compound semiconductor has optical ...

Sensitive operation of passive sensors in a radiation environment requires a means to eliminate the signals caused by ionizing radiation. Black Forest Engineering proposes a signal processing technique to delete these gamma-spike signals that can be integrated into each unit cell of an infrared planar hybrid sensor chip assembly. This technique is applicable to both scanning and staring systems wi ...

A NOVEL LIQUID CRYSTAL BEAM IS PROPOSED. THE ACTIVE MATERIAL PRODUCES ANALOG PHASE MODULATION (NEARLY 2 PI) WITH A SUB-MICRON LAYER, SWITCHING AT MICROSECONDS. TO ACHIEVE LARGE STEER ANGLES AND HIGH DIFFRACTION EFFICIENCY, HIGH SPATIAL FREQUENCY STRUCTURES WITH ANALOG PHASE ARE REQUIRED. THE NEMATIC MATERIALS CURRENTLY USED FOR SUCH DEVICES EXHIBIT SLOW RESPONSE TIMES, AND LIMITED RESOLUTION. WHIL ...
