An inertial navigation system with error correction based on navigation map

摘要

An inertial navigation system with error correction based on a navigation map is disclosed herein. The inertial navigation system can include a trajectory calculator for calculating a position and an orientation of a moving object based on moving information of the moving object, an error correcting unit coupled to the trajectory calculator for correcting the position and the orientation of the moving object based on reference road information, and a storage unit coupled to the error correcting unit for storing geographical information of a road network and providing the reference road information according to the geographical information of the road network.
