Abstract: A method of pedestrian navigation based on an external positioning system and a Dead Reckoning (DR) system, us provided. The method includes: obtaining DR position readings from a plurality of pedestrian-carried platforms and external position readings from a remote source which is independent of the pedestrian-carried platforms, wherein the obtaining is repeated for a plurality of locations associated with the plurality of pedestrian-carried platforms; estimating, for each of the plurality of locations, an external positioning source error, based at least partially on the external position readings and the DR position readings; applying an estimation function to the external position readings, the DR position readings, and the external positioning source error, for the plurality of locations, to yield a corrected estimated position for each of the plurality of locations; and presenting the corrected estimated position for each of the plurality of locations to users of the pedestrian-carried platforms, respectively.
