Joint GNSS and 3GPP-LTE Based Positioning in Outdoor-to-Indoor Environments - Performance Evaluation and Verification

Armin Dammann, Emanuel Staudinger, Stephan Sand, Christian Gentner

Abstract:	Indoor positioning is an extremely challenging task for GNSS positioning. Thus, we propose to use terrestrial communications systems such as 3GPP-LTE as a complementary positioning system. We estimate the expected positioning performance of 3GPP-LTE indoor positioning by assessing link budgets and calculating the Cramer-Rao lower bounds for pseudo-range and 2D position estimation. An experiment shows that the combination of mobile radio based positioning can achieve a positioning accuracy in the range of a few meters, indicating that such technologies are suitable for complementing GNSS indoors.
