Beschreibung
Zusammenfassung:	Aspects of the present invention relate to systems, methods, and computer program products for tracking an orientation of an object. The system includes a first sensor that measures the orientation of the object relative to an external reference frame and generates an orientation signal based on the measured orientation of the object, the first sensor being subject to drift over time; a second sensor that receives a global positioning system (GPS) signal and generates a drift compensation signal based on the received GPS signal; and a processor coupled to the first sensor and the second sensor, the processor generating a drift-corrected orientation signal based on the orientation signal from the first sensor and the drift compensation signal from the second sensor.
