A method of detecting dislodgement of a navigational reference within a localization field, the method carried out by a processor and comprising: obtaining a reference location from at least one reference location element of a reference catheter secured within a localization field; measuring a location of the at least one reference localization element within the localization field; computing a slow-moving average location of the at least one reference localization element; computing a fast-moving average location of the at least one reference localization element; computing a distance between the slow- and fast-moving average locations of the at least one reference localization element; comparing the computed distance to a dislodgement threshold; if the computed distance exceeds the dislodgement threshold: for the at least one reference localization element: computing a vector connecting the slow- and fast-moving average locations of the respective reference localization element at a point in time when the computed distance between the slow- and fast-moving average locations of the respective reference localization element exceeded the dislodgement threshold; determining an axis of the reference catheter at the point in time when the computed distance between the slow- and fast-moving average locations of the respective reference localization element exceeded the dislodgement threshold; and computing an angle between the computed vector and the axis of the reference catheter, thereby computing at least one angle associated with the at least one reference localization element; and analyzing the at least one angle for an indication that the reference catheter has dislodged from the reference location. obtaining a reference location from at least one reference location element of a reference catheter secured within a localization field; measuring a location of the at least one reference localization element within the localization field; computing a slow-moving average location of the at least one reference localization element; computing a fast-moving average location of the at least one reference localization element; computing a distance between the slow- and fast-moving average locations of the at least one reference localization element; comparing the computed distance to a dislodgement threshold; if the computed distance exceeds the dislodgement threshold: for the at least one reference localization element: computing a vector connecting the slow- and fast-moving average locations of the respective reference localization element at a point in time when the computed distance between the slow- and fast-moving average locations of the respective reference localization element exceeded the dislodgement threshold; determining an axis of the reference catheter at the point in time when the computed distance between the slow- and fast-moving average locations of the respective reference localization element exceeded the dislodgement threshold; and computing an angle between the computed vector and the axis of the reference catheter, thereby computing at least one angle associated with the at least one reference localization element; and analyzing the at least one angle for an indication that the reference catheter has dislodged from the reference location. for the at least one reference localization element: computing a vector connecting the slow- and fast-moving average locations of the respective reference localization element at a point in time when the computed distance between the slow- and fast-moving average locations of the respective reference localization element exceeded the dislodgement threshold; determining an axis of the reference catheter at the point in time when the computed distance between the slow- and fast-moving average locations of the respective reference localization element exceeded the dislodgement threshold; and computing an angle between the computed vector and the axis of the reference catheter, computing a vector connecting the slow- and fast-moving average locations of the respective reference localization element at a point in time when the computed distance between the slow- and fast-moving average locations of the respective reference localization element exceeded the dislodgement threshold; determining an axis of the reference catheter at the point in time when the computed distance between the slow- and fast-moving average locations of the respective reference localization element exceeded the dislodgement threshold; and computing an angle between the computed vector and the axis of the reference catheter, thereby computing at least one angle associated with the at least one reference localization element; and analyzing the at least one angle for an indication that the reference catheter has dislodged from the reference location.
