There are many situations in which global navigation satellite systems (GNSS) such as the global positioning system (GPS) cannot provide adequate navigation performance (such as indoors or in urban canyons). This paper describes the technical challenges of non-GNSS radio frequency navigation, with particular emphasis on signals of opportunity (i.e., signals(More)
This paper presents a numerical approach to the mapmatching problem. The proposed solution is based on a sequential Monte Carlo method, so called particle filtering. This algorithm can be adapted for implementation on real-time car navigation systems using a low-cost MEMS heading rate sensor and standard vehicle speed sensor installed in the car as(More)
