International Classification:
G01S 19/40
G01S 19/09
G01S 19/09
US Classification:
34235723, 34235746
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.
System And Method For Determining The Time Difference Of Arrival Of A Frequency Shift Keyed Signal At Two Separate Receivers
View pageUS Patent:
61378429, Oct 24, 2000
Filed:
Nov 28, 1997
Appl. No.:
8/979633
Inventors:
Peter C. Grossnickle - San Diego CA
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
H03D 300
US Classification:
375334
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. A second computer estimates second frequency shift times of the FSK signal using the second series of signal samples and time reference signal, and determines the path difference between the FSK signal source and each of the first and second receivers using the first output signal containing the first frequency shift times, and the second frequency shift times. The invention obviates the need for providing a replica of the first signal samples to the second computer.
