Description
Summary:Passive magnetic sensors can measure the magnetic field density in three orthogonal axes and are often integrated on a single chip. These sensors are low-cost sensors and widely used in car navigation as well as in battery powered navigation equipment such as smartphones. There, its general purpose is the measurement of the heading angle by an electronically gimbaled compass technique. We are interested in train localization with multiple, exclusively onboard sensors and a track map. This approach is considered as a base technology for future railway applications such as train-centric train control, collision avoidance systems and autonomous driving. It has been shown that active magnetic measurements, such as a metal detector, is very beneficial for onboard train localization.
