The present invention is a method and apparatus for providing anti-jam protection
for GPS receivers. The anti-jam system of the present invention may require less
space and less power than conventional anti-jam systems. The anti-jam circuitry
of the present invention may provide anti-jam protection while reducing the number
of high-power usage components and integrating the components into an overall reduced
form factor. Complex signal processing may be avoided whereby hardware manipulations
are handled by hardware components rather than a digital signal processor.
