Inertial Navigation combined with other navigation supports like GPS, has gained importance due to enhanced navigation and inertial reference performance. The INS individually can compute the position of the device without any help from the outside world. However, a huge number of errors are introduced by sensors giving rise to an unacceptable drift in the output. So, a GPS is used to help the INS, using a Kalman filter which helps in estimating the errors in the INS and thus updating position to improved accuracy.
