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 ...

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 ...

An adaptive attitude control system for a space-based interceptor will ameliorate the effects of torque disturbances when firing a divert thruster with the line of force offset from its center of mass. The adaptive control algorithm is based on a simplified version of a model reference adaptive control concept. It possesses two features: (i) more robust performance for the interceptor guidance and ...

To improve automated target tracking and correlation for strategic defense, this proposal models the dynamic behavior of manuevering vehicles by allowing target heading and speed, or their derivatives, to undergo independent diffusion processes. Current methods for surveillance sensors model diffusion in geographically fixed coordinate systems and fail to exploit course/speed nonlinearities, and k ...

SDI requires dual band imaging technology. The approach may provide equivalent performance at far lower cost than discrete element IRFPA technologies. The project will develop a dual band IR imager using its photodichronic imaging (PDI) technology. A sensitive 8 to 12 micron imager has been demonstrated. Similarly designed materials have been demonstrated to be sensitive to different IR spectral b ...
