dc.description.abstractThis thesis investigates the ability of a vector-based Global Positioning System (GPS) receiver and an ultra-tight GPS/inertial receiver to detect and mitigate Continuous Wave (CW) interference in tracking and navigation domains. In this work, an Interference Detector (ID) is incorporated into the tracking domain of a GPS software receiver and a new observation weighting (OW) algorithm is developed to help classify GPS measurements when CW signal is present. Results show that both vector-based and ultra-tight GPS receivers, accompanied by the ID and OW, offer better navigation solution accuracies in CW jamming than their un-aided counterparts. Specifically, aided receivers improved the horizontal position approximately by a factor of two, while the horizontal velocity errors of the aided vector-based receiver were reduced by a factor of four compared to that of the un-aided counterpart during interference. Also, the novel OW technique set more appropriate observation variances than the carrier-to-noise (C/N0) weighting in jamming.en_US
