Abstract:
This paper presents a brief overview of how opportunistic signals can be utilised for localisation. Two different techniques for using opportunistic signals have been implemented and are validated through a number of experiments. These experiments show the performance of the navigation system when configured to use different signal types including Medium Wave radio, Digital Audio Broadcast, GSM and 3G. The same dataset is used for each experiment and uses data simulated from real transmitters operational in the Sydney region which enables a comparison of the performance benefits of using different signal types in this environment.


Results show that there are three dominant factors that contribute to the quality of the solution; accuracy of the timing information contained in the signal, and the quantity and location of the transmitters used for the estimation.
