APPARATUS AND SYSTEM FOR SIMULATING NAVIGATION SIGNAL IN JAMMING ENVIRONMENT

摘要

A navigation signal simulation apparatus in a jamming environment according to the present invention includes an antenna for receiving a navigation signal of a navigation satellite, an interference signal generation unit for generating a interference signal to limit a normal reception of the navigation signal, and a navigation signal synthesis unit for synthesizing the navigation signal and the interference signal and outputting the synthesized signal to an antenna input port of a satellite navigation receiver. Accordingly, an interference signal and a navigation signal can be reliably simulated using a simple construction when they enter an antenna at the same time.
