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 ...

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 ...

A GREAT DEAL OF EFFORT HAS BEEN SPENT IN RECENT YEARS TO DEVELOP STANDARDIZED METHODOLOGIES FOR ACCEPTING AND VERIFYING EMP HARDENED MILITARY FACILITIES. THE FIRST OF THESE STANDARDIZATION EFFORTS TO BE PUT INTO EFFECT APPLIES TO FIXED SITE, CRITICAL, TIME URGENT C4I FACILITIES. THE REQUIREMENTS EXISTS FOR AN ADVANCED INSTRUMENTATION APPROACH THAT CAN OVERCOME THE DIFFICULT ACQUISITION ENVIRONMENT ...

ONE COMMON NUCLEAR WEAPONS EFFECTS CIMULATION TECHNIQUE SIMULATES THE EMP RESPONSE OF LONG CABLES USING DIRECT CURRENT INJECTION. DIRECT CURRENT INJECTION TYPICALLY INVOLVES THE CONNECTION OF HIGH VOLTAGE PULSE SOURCES TO THE CABLES THAT ARE ATTACHED TO A MILITARY SYSTEM. A RECENTLY DEVELOPED MILITARY STANDARD SPECIFIES THAT DIRECT CURRENT INJECTION TESTING WILL BE USED IN CONJUNCTION WITH SEVERAL ...

PLASMA EROSION OPENING SWITCHES (PEOS) ARE FINDING MANY APPLICATIONS IN PULSE POWER MULTIPLICATION AND THE SWITCHING OF INDUCTIVE STORAGE DEVICES FOR PULSED POWER APPLICATIONS. SUCH A SWITCH OPERATES BY USING AN EXTERNAL PLASMA SOURCE TO SHORT A GAP WHICH CONDUCTS CURRENT FROM A LOW VOLTAGE CAPACITIVE SOURCE FOR 100 NANOSECOND TIME SCALES. AT A CRITICAL CURRENT DENSITY THE PLASMA ERODES AND THE SW ...

A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THA ...
