VLC based indoor positioning using single-Tx and rotatable single-Rx

We proposed a two-dimensional positioning system and an algorithm using single transmitter and receiver. The system is using modeled characteristics of device which is based on the experimentally measured. We were able to obtain the estimated position with less than 3 cm of error when polar angle was 15 degrees and the azimuth angles of PD were 45, 315, and 135 degrees.
