Abstract

A network positioning system (NPS) uses GNSS-like signals transmitted from a GNSS-synchronized network of terrestrially based, low cost positioning-unit devices. These positioning-unit devices are used for the determination of absolute and relative position in satellite obscured environments, thus allowing seamless transition between GNSS and NPS, e.g., outdoors to indoor. Positioning-unit devices are self-integrating, thus allowing effortless integration of positioning-unit devices into both the GNSS and the NPS network.
