This repository provides an indoor Optical Wireless Positioning (OWP) + Inertial Measurement Unit (IMU) fusion positioning dataset comprising over 110 K continuous samples collected over more than 80 minutes. The data acquisition rates are:
- RSS measurements: 27 Hz
- IMU readings: 200 Hz
- Ground truth (position & attitude): 160 Hz

The vehicle traverses the floor while on-board sensors capture RSS values from ceiling-mounted infrared LEDs.
The ceiling is equipped with four infrared LEDs, each modulated at a unique frequency for optical ranging calibration. |
Schematic annotation includes LED mounting positions. |
