چکیده
The article discusses an important issue of railway line construction and maintenance, which fundamentally is the verification geometric parameters track. For this purpose, mobile measurements have been performed using a measuring platform with two properly arranged GNSS receivers, made it possible to determine base vector platform. functionality system was extended by IMU. In article, effect conditions on accuracy results collected from receivers analyzed. particular, advisability digital filtering recorded coordinates eliminate disturbances indicated. also presents use devices IMU unit for determining direction angle longitudinal lateral inclination angles This makes verify track geometry in horizontal plane positions straight sections, circular arcs, transition curves. It indicated that are repeatable despite dynamic interaction between confirm usefulness applied signal processing method monitoring geometrical operating conditions.

متن کاملA New Filtering and Smoothing Algorithm for Railway Track Surveying Based on Landmark and IMU/Odometer
High-accuracy railway track surveying is essential for railway construction and maintenance. The traditional approaches based on total station equipment are not efficient enough since high precision surveying frequently needs static measurements. This paper proposes a new filtering and smoothing algorithm based on the IMU/odometer and landmarks integration for the railway track surveying. In or...
