The present disclosure describes a self-positioning system, a tracking beacon and a self-positioning method for a vehicle. The self-positioning system is configured to estimate an direction of arrival of a radio wave tracking beacon signal arriving at an antenna array of the vehicle from a non-stationary tracking beacon unit, estimate Euclidian distance between the self-positioning system and the tracking beacon unit by using wireless radio-frequency communication between the self-positioning system and the tracking beacon unit, and determine position data identifying a three-dimensional position of the self-positioning system with respect to tracking beacon unit on the basis of the estimates of the direction of arrival and the Euclidian distance.
