GPS JAMMING SIGNAL DETECTION APPARATUS FOR DISTURBING GPS RECEPTION

摘要

PURPOSE: A GPS jamming signal detecting apparatus is provided to prevent disruption due to GPS disable in advance by rapidly converting a GPS into an alternative service means.;CONSTITUTION: An RF signal intensity detection unit(12) detects the intensity of an RF signal of a GPS frequency band received in an antenna. A signal processor(13) processes the RF signal of the GPS frequency band and extracts GPS information. A jamming signal determining unit(14) determines the reception of a jamming sign by using the intensity of the RF signal of the GPS frequency band received detected in the RF signal intensity detection unit or the GPS information extracted in the signal processor. A jamming alarm output unit(15) informs the reception of the jamming signal in case the jamming signal exists.;COPYRIGHT KIPO 2012
