Precise location and projection by radio beacon signals

Various embodiments herein each include at least one of systems, methods, software, and devices for precise location and projection by radio beacon signals. One such embodiment, in the form of a method that may be performed in whole on a mobile device or on a mobile device in communication with a server based system. The method includes iteratively determining an unfiltered location. The unfiltered location is determined based on at least three received beacon signals and beacon location data retrieved from a database for the beacons from which the beacon signals were received. The method then applies a triangulation algorithm to the beacon location data. The method may continue in some embodiments by then determining a filtered location based on recent unfiltered locations while disregarding unfiltered locations determined to be bad signals. A path may then be projected based on filtered and unfiltered locations.
