Abstract
In an embodiment a method includes emitting at least one group of at least N+1 mutually temporally asynchronous synchronization signals from at least N+1 fixed emitting locations in a space, receiving the synchronization signals of the group by a mobile device and at at least one fixed receiving location in the space, determining a reception moment of each synchronization signal of the at least one group by the mobile device in a time base specific to the mobile device, determining a reception moment of the synchronization signals of the at least one group at the at least one receiving location in a time base specific to each receiving location, and determining a position of the mobile device in the space at a given moment based on the reception moments determined at the at least one receiving location, the reception moments determined by the mobile device, coordinates of the emitting locations in the space and a distance between each emitting location and the at least one receiving location.
