Abstract

Using current GPS receivers, is not possible to navigate (explore) inside a building. Seoul National University (SNU) has developed a closed-space navigation system based on pseudo-satellites in which the results of the RMS errors are limited to 1-2 mm in determining the static position and to 5-15 mm in the dynamic position determination.
