Scheme Design and Simulation of Hybrid Navigation System Composed of a Strapdown Inertial Reference System and an Odometer

Focused on shortcomings of vehicle-mounted positioning and orientation system, a new vehicle-mounted positioning and orientation system was designed. The scheme design and simulation of the hybrid system were finished which is composed of a strapdown inertial reference system and an odometer with low cost, high reliability and very high resolution. The simulation results show that the system is featured with high alignment precision for attitude angle error and heading angle error and period stopping for system verification is no longer required.
