Abstract

Network based geographic localisation has been widely researched in recent years due to the need to locate mobile data communication nodes to a level of accuracy equivalent to that provided by global navigation satellite systems (GNSS) in multipath urban and indoor environments. This paper investigates whether direct sequence spread spectrum (DSSS) signal processing can be applied to narrow-band radio channels to improve the ranging estimates. The DSSS signal processing application is then developed further to provide a method of deriving a measurement confidence indicator, allowing the optimisation of time separated measurements in a dynamic signals of opportunity radio environment. A set of validation tests demonstrates that the proposed method provides a significant improvement in the accuracy and robustness of the ranging estimate compared to simple threshold analysis in multipath environments.
