Basic model for PDR algorithm. Starting from the user's initial position (x0, y0), we can calculate the next position, notated as (x1, y1), by utilizing the heading angle θ1 and the displacement d1. Based on the iterative process of position calculation, the coordinates of the user's k th position are calculated by (1).
