ABSTRACT:
A method for determining rotational position of a target in a target tracking System is disclosed. The target comprises a plurality of light emitting elements arranged circumferentially around the target. The target tracking System further comprises a tracker unit capable of detecting light emitted by said light emitting elements. The method comprises the Steps of emitting from said light emitting elements an omni-directional synchronization signal; detecting in the tracker unit said synchronization signal; activating said light emitting elements sequentially starting from a reference direction, wherein each light emitting element is activated for a predetermined time and emits light during the time it is activated; detecting in the tracker unit a time when a maximum amount of light is received from the target; and calculating the reference direction for the target relative to a coordinate System based on the time interval between detection of the synchronization signal and the detection of a maximum amount of light received from the target. An active target for use in the method is also disclosed.
