Abstract: The apparatus includes a first frequency conversion unit that converts a radio frequency (RF) signal of a first satellite into an intermediate frequency (IF) signal, a signal processing unit that acquires signal processing information by performing signal tracking with respect to the converted IF signal, a jamming determination unit that determines whether a jamming signal is generated based on the acquired signal processing information, and a signal complex processing unit that performs signal processing with respect to an RF signal of a second satellite based on the signal processing information to thereby generate a navigation message of the first satellite when the jamming signal is generated. Accordingly, a Global Positioning System (GPS) receiver that is installed in a fixed point may acquire stable visual information even in an environment in which a jamming signal is generated.
