Raw recordings and derived data for wearable UWB TDOA positioning: tag-, orientation- and placement-dependent bias (office campaign, October 2026)

Data supporting the manuscript "What Anchor Calibration Cannot Fix: Tag-, Orientation- and Placement-Dependent Bias in Wearable UWB TDOA Positioning for Occupational Safety" (E. Mert, F. Kaçar), submitted to Sensors (MDPI), manuscript sensors-4679143. The record contains (1) Minimal_Dataset_UWB_TDOA.zip: the derived tables behind every table and figure of the manuscript, with the figure script; and (2) one ZIP per recording session (31 sessions, 7.6 GB uncompressed, 4.2 GB as ZIPs): a lossless capture of every UDP datagram received by the positioning server (DW1000 receive timestamps, synchronisation frames and per-link power from five anchors), the session metadata with the full configuration and laser-surveyed test points, and the live position output. A session can be re-processed with a different clock model or solver. README.md gives the raw record format and the session-to-experiment table; MANIFEST.csv and SHA256SUMS.txt give file sizes and checksums. Recordings were made in an office with DWM1000 anchors and DWM1001 tags on desks or carried by a member of the research team. No personal data are included.
