Abstract

A position detection system includes: a detection target; detection coils each outputting a detection signal of strength of the alternating magnetic field; a guidance magnetic field generator including a magnetic field generation source, and a driving mechanism, wherein at least a part of the guidance magnetic field generator is formed of a conductor that generates an interference magnetic field; and a processor configured to: control an operation of the driving mechanism; calculate a correction value by using at least one of a position and a posture of the conductor; correct the measured value by using the correction value; and calculate at least one of a position and a posture of the detection target based on the corrected measured value.
