A method of pedestrian navigation, based on an external positioning system and a Dead Reckoning (DR) system is provided herein. The method may employ the following steps: obtaining external positioning readings from an external positioning source and DR position readings from a pedestrian-carried platform; estimating an external positioning error, based at least partially on the external positioning and the DR position readings; and applying an estimation function to the external position readings, the DR position readings, and the external positioning errors, to yield a corrected estimated position. |
