Abstract :
The paper presents the results of development of the Optical-Inertial System for Railway Track Diagnostics. It is demonstrated that in order to implement the solution at a speed of up to 430 km/h while satisfying the accuracy of 0.1...0.5 mm during measurement of longitudinal level, cross level, twist, curvature, rail profile, etc., it is needed to combine the optical scanners of the inner profile of the rail line with the strapdown inertial navigation system (SINS) in a single block. The possibility of using SINS based on fiber-optic gyros (FOG) for railway applications is considered in the article. Some practical results are given.
