Apparatus and method for detecting location information using navigation algorithm

摘要

A method and apparatus for detecting location information using a navigation algorithm are provided. The method includes searching for neighboring Global Positioning System (GPS) satellites, receiving, if at least one GPS satellite is detected, pseudo-range information from at least one of the detected GPS satellites and storing the received pseudo-range information, calculating a displacement of a pedestrian terminal based on step detection of a pedestrian, correcting the calculated displacement of the pedestrian terminal using the received pseudo-range information, and measuring the location of the pedestrian terminal is measured using the corrected displacement.

1. A method for measuring a location of a pedestrian terminal, the method comprising:
receiving pseudo-range information from at least one of Global Positioning System (GPS) satellite and storing the received pseudo-range information; calculating a displacement of a pedestrian terminal based on a detected number of steps taken by a pedestrian; calculating a distance between the pedestrian terminal and the at least one GPS satellite using the calculated displacement of the pedestrian terminal and orbit information about the at least one GPS satellite; correcting the calculated displacement of the pedestrian terminal using a difference between the received pseudo-range information and the calculated distance; and measuring the location of the pedestrian terminal using the corrected displacement.
