Abstract

In indoor environments, GNSS signals endure serious attenuation, hence a GNSS receiver could not output accurate, reliable positioning solutions continuously. Pseudolite positioning system was proposed as a suitable alternative solution for indoor positioning applications. In this research, a new indoor pseudolite positioning system based on carrier phase interferometry technique is presented. This pseudolite-based positioning system can achieve decimeter accuracy without the support of a base station, and without the need of synchronization between pseudolites. In addition, in the proposed new positioning system the integer ambiguity resolution is unnecessary as well. In this pseudolite system, the main part of interferometric measurement is a dual-antenna software receiver. By using the principle of interferometric measurement, dual-antenna software receiver could deduce the spatial relationship between the dual-antenna and pseudolites. As a result, dual-antenna’s position can be determined uniquely. Experiment results demonstrate that a horizontal positioning accuracy of decimeter-level accuracy can be obtained.
