A locating system for determining the location and orientation of an invasive medical instrument, for example a catheter (

10

) or endoscope, relative to a reference frame, comprising: a plurality of field generators (

18, 20, 22

) which generate known, distinguishable fields, preferably continuous AC magnetic fields, in response to drive signals; a plurality of sensors (

30, 32, 34

) situated in the invasive medical instrument (

10

) proximate the distal end thereof which generate sensor signals in response to said fields; and a signal processor (

26

) which has an input for a plurality of signals corresponding to said drive signals and said sensor signals and which produces the three location coordinates and three orientation coordinates of a point on the invasive medical instrument.
