  • Global positioning system (GPS) and doppler augmentation (GDAUG) and space location inertial navigation geopositioning system (SPACELINGS)
    Patent number: 9019155
    Abstract: A global positioning system (GPS) and Doppler augmentation (GDAUG) end receiver (GDER) can include a GDAUG module. The GDAUG module can generate a GDER position using a time of flight (TOF) of a transponded GPS signal and a Doppler shift in a GDAUG satellite (GSAT) signal. The transponded GPS signal sent from a GSAT to the GDER can include a frequency shifted copy of a GPS signal from a GPS satellite to the GSAT. The GSAT signal can include a signal generated by the GSAT to the GDER.

  • Countermeasure system and method using quantum dots
    Patent number: 7916065
    Abstract: In one embodiment, a countermeasure system for protecting an asset from a missile attack includes a decoy comprising a plurality of quantum dots selected to emit radiation having a radiation emission profile similar to a profile of a radiation signature of the asset. In another embodiment, a method of simulating a radiation signature of an asset using quantum dots includes dispersing quantum dots to form a cloud of quantum dots; and exciting the quantum dots with a first radiation so that the quantum dots emit a second radiation having a profile similar to the radiation signature profile of the asset.

  • Antenna test and measurement system
    Patent number: 4884078
    Abstract: An improved antenna test and measurement system including a transmit antenna; means for providing a test signal to said transmit antenna and initiating the transmission thereof; a receive antenna adapted to receive the test signal as transmitted by said transmit antenna; an amplitude detector for detecting the amplitude of the received test signal; and an open loop phase detector for measuring the phase of the received test signal relative to a reference signal.
