A position tracking system is disclosed which derives information relating to a location of a cart or trolley, such as a shopping trolley in a supermarket. The cart comprises at least one wheel that is configured to acquire and output information representing a rotational distance travelled by the wheel and to determine and output a bearing of the wheel during motion, for example using an encoder, gyroscope, magnetometer, accelerometer or similar sensors. The system obtains information relating to an estimated change in a position of the cart and identifies, based on the wheel information, at least one location at which the cart was located. The wheel may also include means for wireless communication and wireless signal triangulation positioning may be used. Position estimates may include generating candidate state particle sets. Specific locations may be identified such as checkouts, aisles, near items of interest and restricted areas, for example to prevent the trolley being stolen.
