SATELLITE NAVIGATION DISTURBANCE SIGNAL GENERATING SYSTEM OF A SATELLITE NAVIGATION SIMULATOR, CAPABLE OF CONSIDERING THE FREQUENCY VARIATION, THE ATTENUATION RATE, THE PHASE CHANGE AND THE SIGNAL DELAY DEPENDING ON THE POSITIONAL CHANGE OF A DISTURBANCE SIGNAL GENERATOR AND A SATELLITE NAVIGATION RECEIVER

摘要

PURPOSE: A satellite navigation disturbance signal generating system of a satellite navigation simulator is provided to generate a disturbance signal under an environment which is dynamic and similar to an actual environment, thereby enabling analysis of the effect of the disturbance signal generated under various environments.;CONSTITUTION: A satellite navigation disturbance signal generating system of a satellite navigation simulator is as follows: A satellite navigation disturbance signal simulator controller(10) generates positional information of a satellite navigation receiver(2) and positional information of a disturbance signal source in real time. A satellite navigation signal simulator(1) generates a satellite navigation signal based on the positional information of the satellite navigation receiver, by inputting the positional information of the satellite navigation receiver generated from the satellite navigation disturbance signal simulator controller. A disturbance signal generation controller(20) respectively calculates frequency variation, attenuation rate, and phase delay using the positional information of the satellite navigation receiver generated from a satellite navigation disturbance signal simulator controller and disturbance signal source. A signal generator(30) generates the disturbing signal frequency variation, the attenuation rate, and the phase delay calculated from a disturbance signal generation controller. A signal coupler(40) generates the satellite navigation signal including the disturbance signal by coupling the satellite navigation signal transmitted from a satellite navigation signal simulator and the disturbance signal transmitted from the signal generator. A satellite navigation receiver receives the satellite navigation signal including the disturbance signal generated from the signal coupler.;COPYRIGHT KIPO 2013;[Reference numerals] (1) Satellite navigation signal simulator; (10) Satellite navigation disturbance signal simulator controller; (2) Satellite navigation receiver; (20) Disturbance signal generation controller; (30) Signal generator; (40) Signal coupler
