In this paper, the Kalman filter (KF) has been implemented as the primary integration scheme of the global positioning system (GPS) and inertial navigation systems (INS) for many land vehicle navigation and positioning applications. However, it has been reported that KF-based techniques have certain limitations, which reflect on the position error accumulation during GPS signal outages. Therefore, this article exploits the idea of incorporating artificial intelligence to develop an alternative INS/Differential-GPS (DGPS) integration scheme, the intelligent navigator, for next generation land vehicle navigation and positioning applications.
