Abstract

In order to achieve indoor positioning, and hence a real continuity of the positioning service in all environments, we designed a new pseudolite-based system using the so-called repealites. A single GNSS-like signal is transmitted from all the repealites (typically 4 for 3D positioning): this approach simplifies both the synchronization process (between transmitters) and the indoor interference between pseudolites. In addition, in order to avoid intentional artificial multipath, the signals from two repealites are shifted in time by a few chips. This approach has already been described in previous conferences.
