Method, mobile device, computer program product, and apparatus for performing Positioning System Enhancement is described. A visible light communication (VLC) signal is received at a mobile device in an environment and the mobile device measures an external field in response to receiving the VLC signal. The mobile device decodes an identifier from the VLC signal and determines a relative position to the VLC signal source. The mobile device sends information to a server. The information sent to the server includes the identifier, position, and external field measurement. The server calculates position within the heatmap according to the identifier and relative position received from the mobile device. The server updates the heatmap according to the position of the mobile device and respective external measurements at the position. |
