Abstract
A method, apparatus and computer readable storage medium are provided to determine motion information associated with a mobile device. A plurality of signal propagation time parameters are obtained or determined. Each signal propagation time parameter is associated with a respective observation position of the mobile device and a respective installation position a radio device. Each signal propagation time parameter is representative of a respective signal propagation time value of radio signal(s) traveling between the respective observation position and the respective installation position. For each of the installation positions of the radio devices, respective point coordinates are determined that represent the respective installation position of the respective radio device, at least partially based on the signal propagation time parameters. Motion information associated with the mobile device is determined at least partially based on the signal propagation time parameters and the point coordinates that have been determined.
