A receiver system for use in LIDAR consisting of an optical filter and optical spectrometer based upon two-photon absorption is proposed. The filter and spectrometer both use dispersion from excited state transitions of atomic rubidium to create a birefringent medium. The birefringent medium of the optical filter rotates the polarization of light so that it is transmitted through crossed polariz ...

Legacy GPS receivers do not make use of the disciplined atomic oscillator flywheel output in GPS Disciplined Oscillator systems. The attached proposal shows how the disciplined oscillator signal can be used to improve GPS carrier and code tracking, mitigate multipath, jamming and spoofing, and to detect GPS receiver and satellite system anomalies. Using the disciplined oscillator as the frequency ...

GPS Disciplined Oscillator (GPSDO) systems traditionally combine the 1PPS output from a GPS receiver and highly stable clock like a Chip Scale Atomic Clock (CSAC) to steer the local clock frequency to match the frequency and phase of the GPS-generated 1PPS. However, the GPS receiver does not take advantage of the stable Chip Scale Atomic Clock for improved GPS receiver resilience, improved positio ...

Digital Solid State Propulsion Inc. is proposing the development of a reusable electric blank system that leverages over 10 years of success in formulating, engineering, and manufacturing Electric Solid Propellants for the space, defense, and entertainment industries. DSSP already has a pyrotechnic solution to battlefield effects simulating small arms fire based on eSquib technology, however, for ...

NUMEROUS AIRCRAFT ACCIDENTS HAVE OCCURED DURING TAKEOFF AND LANDING DUE TO THE STRONG AND UNEXPECTED WINDS DIVERGING FROM A MICROBURST OUTFLOW. EXTENSIVE RESEARCH HAS INDICATEDTHAT IT IS POSSIBLE TO DETECT SUCH WINDS BY MEANS OF A DOPPLER WEATHER RADAR. A LOGICAL RADAR CANDIDATE IS THE UNIT CARRIED BY ALL AIR TRANSPORTS. A PROBLEM WITH THE USE OF SUCH INSTALLED RADARS IS THEIR LOWPRF (PULSE REPETI ...

THE LOW COST NON-INTRUSTIVE TORQUE TRANSDUCER IS ADDED TO AN EXISTING DRIVE TRAIN. IT MEASURES DIRECTLY THE ENGINE OUTPUT TORQUE WITH SHORT RESPONSE TIME. THE ANGULAR DEFLECTION AT BOTH ENDS OF THE CRANKSHAFT IS DETECTED BY TWO NON-CONTACTING ENCODER-PICKUP COMBINATIONS. THE PHASE ANGLE BETWEEN THE PULSE TRAINS FROM THE ENCODERS IS PROPORTIONAL TO THE SHAFT DEFLECTION AND THEREFORE A MEASURE OF TH ...
