Abstract
Most GPS equipped platforms currently in use have no anti-jamming capability. However, for various reasons, the cost of replacing the legacy GPS receivers with newer GPS receivers capable of anti-jamming is often prohibitive. Thus, an apparatus having antenna electronics that can perform the anti-jammming function is used to regenerate clean RF signals (with interference removed) to a legacy GPS receiver. With the apparatus, the legacy GPS receiver regards the RF signals as the usual interference-free RF signals.
