摘要： A system for tracking and positioning a moving object, the system including a plurality of transmitters operative to transmit alternating electromagnetic fields within a three-dimensional space and at least one sensor arranged to be fixed to at least one corresponding portion of a moving object whose position it is sought to monitor. Each of said at least one sensors includes an electromagnetic field receiver having at least one active axis and operative to receive at least one component, lying along the at least one active axis respectively, of the alternating electromagnetic fields, an accelerometer to independently measure at least one component of the acceleration of the moving object; and a digital signal processor. The digital signal processor is adapted to store at least one characteristic of the electromagnetic fields as received by the electromagnetic field receiver, and at least one characteristic of the acceleration as measured by the accelerometer, and to transmit the stored characteristics to a Kalman filter, and to compute therefrom an estimate of at least one component of the position and orientation of the moving object.
