Content Inertial Measurement Unit raw data in TXT open and readable format, to be used for processing and testing the pedestrian dead reckoning algorithms by the inertial and indoor tracking scientific community. The raw inertial data have been collected and made publicly available in the frame of the SME Phase 2 project PROTECT (820867), co-funded by the European Commission Experimental data The publicly shared archive contains the following, distinct datasets: RawData_5_2_20191113_180029.decod: collected in Rome (Italy) with the DUNE foot-mounted sensor unit n. 5 on November 13, 2019, in the frame of the project WP3 activities (system scale-up design); aprox. Duration, 30 mins.

RawData_008_06_20191120_182949.decod: collected in Roma (Italy)with the DUNE foot-mounted sensor unit n. 8 on November 20, 2019, in the frame of the WP3 activities (system scale-up design), aprox. Duration, 30 mins. The experiment has a mix of walk and fast run. Open and Accessible Data format The data format is the following gyro(x) gyro(y) gyro(z) acc(x) acc(y) acc(z) mag(x) mag(y) mag(z) temperature altitude x, y, z indicate the axes of the Inertial Measurement Unit gyro stands for the angular velocity and is in rad/s acc stands for the acceleration and is in m/s^2 mag is the magnetic field and is in milligauss temperature is in °C altitude is the output of the altimeter and is expressed in meters All the samples, in all dataset have been recorded with a 200 Hz sampling frequency.
