PROBLEM TO BE SOLVED: To provide a position management system capable of knowing a position of a management object with good accuracy even when there are a few measurement errors.SOLUTION: A position management system 10 includes: a GNSS receiving unit 23; a storage unit 27; a position correction unit 42; and a management unit 30. The GNSS receiving unit 23 measures a position of a portion to be measured (a dashboard of a front passenger seat) of an automobile as a management object. The storage unit 27 stores off-set information which is a difference in positions of the dashboard of a front passenger seat of the automobile and a reference position of the automobile (the center). The position correction unit 42 acquires the position of the center of the automobile based on the position measured by the GNSS receiving unit 23 and the off-set information which the storage unit 27 stores. The management unit 30 manages the automobile by using the position which the position correction unit 42 acquired.
