About

This data set can be used for rail vehicle positioning experiments. It contains measurements of an 6-DOF IMU and a GNSS receiver. The senors were mounted on a regular rail vehicle during a trip from Chemnitz (Germany, Saxony) to Neuffen (Germany, Baden-Württemberg) and back.

The recorded data have been pre-processed to have common time and coordinate frames. Furthermore, a simple loosely coupled GNSS/IMU positioning solution is provided which can be used as a baseline for more advanced fusion approaches.

All MATLAB scripts used to process the raw data and to calculate the GNSS/IMU positioning solution are provided within the data set.

The data can be used as a starting point for own work. Special features of this data set are its overall length (870km, 16hrs) with continuous journey sections of over 1h and its test-track (conventional line).
