A Review of Integrated Navigation System GPS/INS Methods and Study of New Approaches in This Field

The integrated navigation contains Inertial Navigation System (INS),Global Positioning System (GPS) is an important methodin moving vehicles such as ground, sea,aerospace vehicles navigation. This study contains the introduction of INS, theintroduction of GPS, the integration method of above systems,important issues in this field. For these purposes, the mostimportant researches of Iranian,overseas scientists are studied. Besides of issues such as using a Kalman Filter (KF), ExtendedKalman Filter (EKF), Particle Filter (PF),other methods based on KF,PF, the new approaches are also surveyed. The studyresults show that recently using artificial intelligence method in integration, the problem outage or block of GPS signal in integrationand low-cost inertial navigation sensors have been the focus of attentions.
