1. A supplemental GPS System, the system comprising:

  • a. an accelerometer-gyroscopic sensor configured to output heading data of an object and a velocity of the object;

    b. an inertial navigation system; and

    c. a navigation system controller that receives the heading data and the velocity of the object from the accelerometer-gyroscopic sensor and sends the heading data and the velocity of the object to the inertial navigation system,wherein the inertial navigation system receives the heading data and the velocity of the object from the navigation system controller and outputs navigation data for the object, wherein the system is configured to provide navigation data during periods of connection loss with a GPS satellite system, and wherein the GPS satellite system takes priority when available.
