Contact person(s): Enrico de Marinis Data collector(s): Enrico de Marinis. Fabrizio Pucci, Michele Uliana Data curator(s): Guido Rosi Work package leader(s): Fabrizio Pucci; Fabio Andreucci 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_20200729_141819_000002_000003_007.decod.grz: collected in Pisa (Italy) with the DUNE foot-mounted sensor unit on July 29, 2020, in the frame of the project WP4 activities (system demonstration).

Images of the experimental data For each of the above data files, the image of the corresponding PDR (Pedestrian Dead Reckoning) processed track has been added as a geo-referenced JPG capture overlaid on the location satellite image. The image file name is the same as the corresponding data file.
