Gps Receiver With Recalibration And Methods For Recalibrating And Reconfiguring A Gps Receiver
US Patent:
6771212, Aug 3, 2004
Filed:

Assignee:
General Dynamcis Corporation - Scottsdale AZ
International Classification:
H04B 7185
US Classification:
34235706, 34235712
Abstract:
A method of recalibrating a Global Positioning System (GPS) receiver includes applying a first control signal to an oscillator for generation of an oscillator signal having an initial frequency and determining if an indicator of correct oscillator output frequency is present at the initial frequency. If an indicator of correct oscillator output frequency is not present, then iterative steps are followed until an indicator of correct oscillator output frequency is found. The iterative steps include: applying a new adjusted control signal to the oscillator for generation of a new frequency; determining whether an indicator of correct oscillator frequency is present; and if an indicator of correct oscillator output frequency is present with the oscillator having the new frequency, storing said adjusted control signal. If an indicator of correct oscillator frequency is present with the oscillator output signal having said initial frequency, then storing said initial control signal.
Method And System For Detecting Interference For Global Positioning Systems
US Patent:
RE41382, Jun 22, 2010
Filed:
May 20, 2009
Appl. No.:
12/469142

Assignee:
General Dynamics C4 Systems, Inc. - Scottsdale AZ
International Classification:
G01S 5/14
US Classification:
34235702, 34235706, 34235709
Abstract:
A method and system for detecting GPS interference is disclosed. In one exemplary embodiment, a method for detecting interference in a Global Positioning System comprises the steps of receiving at least one satellite signal from one or more satellites in a Global Positioning System; identifying a noise floor value from the at least one satellite signal; identifying an interference signal based on the noise floor value; determining an interference value for the interference signal from the noise floor value wherein a level of the noise floor value corresponds to a level of interference; and providing the interference value to at least one user for informing the user of the interference signal.
