INCREASED JAMMING IMMUNITY BY OPTIMIZING PROCESSING GAIN FOR GPS/INS SYSTEMS

摘要

A method for increasing jamming immunity in a GPS system, comprising the steps of: receiving and down-converting GPS signals to provide sine and cosine information; generating correction information by directly filtering said residual information; correcting operational information in response to said correction information, said operational information including at least one of position, velocity, attitude and alignment information; and using feedback information derived from said operational information to carry out at least one of said steps of receiving and generating GPS residual information. 1894 כ' באלול התשס" ג - September 17, 2003
