Cramer-Rao Bound for Hybrid GNSS-Terrestrial Cooperative Positioning

Artikel i vetenskaplig tidskrift, 2010

In this contribution we derive an expression of the Cramer-Rao bound for hybrid cooperative positioning, where GNSS information is combined with terrestrial range measurements through exchange of peer-to-peer messages. These results provide a theoretical characterization of achievable performance of hybrid positioning schemes, as well as allow to identify critical network configurations and devise optimized node placement strategies.
