Beschreibung
Zusammenfassung:	According to an example aspect of the present invention, there is provided a method and system for determining and tracking an indoor position of an object, the method comprising: using a primary position indication, based on signals received from an external positioning system of at least two different positions of said object to calibrate tracking of a secondary position indication, which is an indoor position, and wherein the tracking of the secondary position comprises: recording acceleration data of a second part of the object, integrating said acceleration data, determining a characteristic position of the cyclically moving second part of the object in subsequent cycles, measuring a geomagnetic first orientation of the second part of the object in said characteristic position, determining the second direction of movement of the first part of the object, computing a velocity of the object in any direction based on the acceleration data, and determining the secondary position indication of said object based on said direction data and said velocity data.
