MULTIPLE SATELLITE NAVIGATION ERROR DETECTION AND THE ANALYSIS APPARATUS WHICH EXTRACTS A SATELLITE SIGNAL IN REAL TIME AND ANALYZES IT WITH A BASEBAND PROCESS METHOD THROUGH A SOFTWARE DEFINED RECEIVER TECHNIQUE

摘要

PURPOSE: A multiple satellite navigation error detection and analysis apparatus is provided to effectively analyze multiple satellite navigation spread error by tracing a spread error reason and storing data.;CONSTITUTION: An error generation informative providing unit(110) generates a GNSS(Global Navigation Satellite System) error event by verifying integrity of a satellite signal received through a satellite navigation complex receiving antenna. A satellite signal receiver(120) distributes the satellite signal received through the satellite navigation complex receiving antenna according to a plurality of satellite navigation modes and respectively inputs it to a plurality of satellite receivers. A satellite signal processing and transmitting unit(130) selects a satellite navigation mode in which an error is detected according to the GNSS error event and changes an error detection satellite signal corresponding to the selected satellite navigation mode into intermediate frequency. A satellite signal collecting and analyzing unit(140) stores the error detection satellite signal transferred from the satellite signal processing and transmitting unit in real time and analyzes a spread error. A satellite signal data storing unit(150) stores the error detection satellite signal and analyzed spread error information.;COPYRIGHT KIPO 2012
