TDOA navigation using CDMA2000 signals — Experimental results

This paper presents results of an experiments on the possibility to estimate position of a CDMA2000 receiver on the basis of TDOA measurements. The hardware and software structure of a navigation receiver used during investigation is briefly described with focus on drawbacks and limitations. The main part of this paper contains basic information about CDMA2000 network in northern Poland, which signals were recorded during tests of TDOA navigation, detailed description of results including maps and discussion of possible improvements of position estimation accuracy.
