Abstract

This publication explores the influence of a realistic multipath channel model to satellite navigation applications in urban environments. In this context we have discovered that there is a tradeoff between accuracy and robustness concerning the bandwidth. While narrow band signals such as GPS C/A, BOC (1,1) proved to be robust especially under shadowing situations the wideband signals lost lock very likely in the shadowing situation while being more accurate in LOS situations. In severe multipath situations we have been able to prove the performance of the particle filter receiver wich is clearly showing a better performance than the conventional receivers and even than a maximum likelihood estimation DLL. Furthermore we have identified critical situations where receivers tend to loose lock.
