An INS and GNSS combined train operation monitoring device positioning system comprises a train operation monitoring host, a GNSS information receiving host, an INS inertial navigation system, a ground information receiving unit and a man-machine interaction unit. The man-machine interaction unit is used for receiving a station track number input by a driver before departure and a driving signal given by the driver at the moment that the head of the train crosses the departure signal machine; the GNSS information receiving host is used for receiving a GNSS satellite positioning signal; the ground information receiving unit is used for receiving insulation joint signals; the train operation monitoring host is used for determining a train head geodetic coordinate as a starting reference point based on a station track number and a driving signal; the INS inertial navigation system calculates a dynamic coordinate variable on the basis of the position of the initial reference point; and the train operation monitoring host is also used for calculating the geodetic coordinate of the head in the train operation process based on the initial reference point and the dynamic coordinate variable, and correcting the position error in the train operation process based on the GNSS satellite positioning signal and the insulation joint signal.
