Abstract
The indoor positioning system includes a mobile device, a remote controller, and three RF positioning devices. The RF positioning devices are located at different locations within an indoor space. The mobile device receives and detects strengths of RF signals from the RF positioning devices, and constructs a grid of relative areas within the indoor space accordingly. The mobile device is controlled by the remote controller to move for a number of distances and directions within the inner space so as to integrate the distances and directions with the gird of relative areas into a coordinate system. The mobile device therefore is able to move precisely within the indoor space, either by the remote controller or autonomously.
