Abstract

A personal inertial surveying system includes an inertial sensor and processing equipment adapted to be mounted to or carried by a person walking through a region being surveyed. As the person walks inaccuracies in position measurement due to drifts in the inertial sensor can be conveniently corrected. Corrections can be performed often during brief pauses as the person paces though the region, resulting in improved accuracy in the survey.
