1. A method of tracking a remote object comprising the steps of:

  • fitting a remote object with a positioning sensor configured to receive and store positioning information when the remote object is in a fix position;

    positioning the remote object in a fix position such that the positioning sensor is capable of detecting an activation signal;

    receiving and storing a predetermined amount of data in the positioning sensor, the data comprising positioning information;

    processing the data to determine the location of the fix position;

    decoding data encoded upon a signal using a matched filter, the data being demarcated into successive data epochs; and

    decoding periodic phase shift-data encoded upon the signal by phase shifts of the data epochs using the matched filter.
