Assessing the Accuracy of Underground Positioning Using Pseudolites

William R. Michalson and Ilir F. Progri

Abstract:	By placing pseudolites at strategic locations in underground locations such as tunnels, it becomes possible to maintain navigation capabilities in situations where signals from the GPS system are unavailable. By knowing the precise location of the pseudolites, and by having one antenna on a vehicle and another fixed in the tunnel, it is possible to quickly resolve ambiguities and achieve high accuracy. The achievable accuracies using such a system are presented in this paper.
