APPARATUS FOR DEALING WITH JAMMING SIGNAL AND METHOD FOR DEALING WITH JAMMING SIGNAL

摘要

An apparatus for dealing with a jamming signal according to an embodiment of the present invention comprises: a first frequency converter for converting an RF signal of a first satellite into an IF signal; a signal processor for acquiring signal process data by tracking the converted IF signal; a jamming determining part for determining whether a jamming signal occurs or not based on the acquired signal process data; and a signal combining processor for if the jamming signal occurs, processing an RF signal of a second satellite and generating a first satellite navigation message. Therefore, a GPS receiver installed at a fixed location can acquire stable visual information even under the environment where the jamming occurs.;COPYRIGHT KIPO 2014;[Reference numerals] (110) Receiver; (120) Signal distributer; (130) Switching part; (140) RF/IF signal converter; (150) GPS L1 signal processor; (160) Jamming determining part; (170) Signal combining processor; (180) IF/RF signal converter; (190) GPS L1 receiver
