An Integrated Inertial-Odometric Navigation System with Satellite Calibration

Special features of the functioning of navigation systems (NS) under urban conditions are considered. The object of studies was an NS built on the basis of inertial and odometer systems. The technology of integration of such systems is proposed. As a kernel, the inertial navigation system SINS-500NS based on fiber-optic gyros is included in this NS. The results of natural development of inertial-odometric NS presented in this paper are given and analyzed.
