1. For use with a mobile object, a system for embedding positional data in a video signal where the positional data is indicative of the position of the mobile object, the system comprising:

  • a positioning receiver associated with the mobile object for obtaining positional data indicative of the position of mobile object from a plurality of positioning satellites;

    a video camera associated with the mobile object for creating the video signal; and

    an encoder for receiving the video signal from the video camera and the positional data from the positioning receiver and modulating the video signal with positional data thereby creating a modulated video signal where the positional data is implicitly part of the modulated video signal for later recovery of the positional data.
