Collaborative GNSS Receiver Architecture for Weak Signal Processing

Andrey Soloviev, Jeffrey Dickman, Jacob Campbell

Abstract:	This paper introduces a concept of collaborative GNSS receiver where individual (non-collocated and asynchronous) nodes exchange their signal and measurement data in order to enhance GNSS navigation capabilities in degraded signal environments such as urban canyons and indoors. The paper specifically addresses the use of collaborative receiver architecture for tracking of weak signals. Algorithmic approaches are described and validated with experimental data. Various applications of the proposed technology are envisioned including localization of cellular phone users for indoor location-based services.
