METHOD FOR MITIGATING ANTI-JAM AND MULTIPATH INTERFERENCE SIGNAL IN A GLOBAL NAVIGATION SATELLITE RECEIVER

摘要

PURPOSE: A jamming signal and multipath interference signal mitigating method in a global navigation receiver is provided to change a received signal received through a GNSS(Global Navigation Satellite System) receiver having multiple antenna into a positioning signal having a maximum signal to noise ratio. CONSTITUTION: A GPS(Global Positioning System) receiver projects the GPS received signal to a subspace to remove jamming signal(100). The GPS receiver projects the GPS signal from which the jamming signal is removed to subspace to remove the multipath interference signal(102). The GPS receiver changes the GPS received signal into the positioning signal having the maximum signal to noise ratio.
