  • Patent number: 8009086
    Abstract: A system and process for the geo-location of an asset given no a priori knowledge regarding time and location of the asset with minimized power consumption is disclosed. In the preferred embodiment, the system is accurate to about 30 meters CEP (50% circular error probable) using just a short segment, e.g., 100-200 ms, of digitized GPS L1 signal data.
    Type: Grant
    Filed: August 16, 2010
    Date of Patent: August 30, 2011
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Peter C. Grossnickle, Heidi L. Buck, Gregory Fleizach, Alan Fronk, Matthew Fong, Barry R. Hunt, Matthew Nicholson, Brian T. Williams

  • Patent number: 6137842
    Abstract: A system determines the time difference of arrival of a frequency shift kd signal (FSK) source at two separate receiver sites. The system includes a first receiver located at a first site for generating a first series of signal samples in response to detecting an FSK signal from a FSK signal source. A second receiver located at a second site generates a second series of signal samples in response to detecting the FSK signal. A first computer estimates first frequency shift times of the FSK signal in response to receiving the first series of signal samples and a time reference signal, and generates a first output signal representing the first frequency shift times.
