Claim 12:
13. A sensor system for monitoring a conveyance system, the sensing apparatus comprising:
a sync sensor located along a pathway of a conveyance apparatus of a conveyance system;
an inertial measurement unit configured to detect the sync sensor and measure accelerations of the conveyance apparatus of the conveyance system along an X axis, a Y axis, and a Z axis; and
a controller configured to analyze the accelerations and determine a position of the conveyance apparatus along the pathway;
wherein the controller is configured to determine the position of the conveyance apparatus along the pathway by determining vibratory signatures along at least one of the X axis and the Y axis in response to the accelerations and comparing the vibratory signature to a vibratory signature of a commissioning run along the second axis.
