An integrated position and direction system and method thereof for determining drift. The integrated position and direction system comprises a satellite positioning system and a digital compass. The satellite positioning system is used for determining position and heading, and the digital compass is used for determining direction. An amount of drift can be determined using the heading and the direction. Knowing the amount of drift, a course compensating for the drift can be determined. Thus, a craft that has drifted from its planned course can be directed to a course that will allow it to reach its intended destination.
