A method of providing cellular telecommunications system service with more precise beamforming to a user equipment situated in a first aircraft that is in-flight, wherein the method is performed by a first network node of a terrestrial cellular telecommunications system, the method comprising: periodically acquiring, via an aircraft navigation broadcast receiver, acquired navigation information transmitted from the first aircraft, wherein the acquired navigation information comprises: an identity of the first aircraft; a position of the first aircraft; an altitude of the first aircraft; and a time value indicating when the position of the first aircraft was determined; using the acquired navigation information to determine that the first aircraft is entering a first coverage area associated with the first network node; when the first aircraft is determined to be entering the first coverage area associated with the first network node, directing a beam towards the first aircraft to establish a first link between the first network node and the user equipment; maintaining the first link between the first network node and the user equipment by transmitting beam steered, Doppler shift compensated downlink signals, and by performing beam steered reception of uplink signals, wherein beam steering is directed toward the first aircraft based on the periodically acquired navigation information, and wherein the Doppler shift compensation is based on one or more determinations of relative velocity between the first aircraft and one or more first antenna nodes associated with the first network node, and compensates for a Doppler shift experienced by the user equipment; detecting that the first aircraft will be leaving the first coverage area that is served by the one or more first antenna nodes and will be entering a second coverage area that is served by one or more second antenna nodes, and responding by causing the one or more second antenna nodes to provide a second link between the user equipment and the one or more second antenna nodes using a same cell identifier and a same frequency allocation to the user equipment as are being used for the first link. periodically acquiring, via an aircraft navigation broadcast receiver, acquired navigation information transmitted from the first aircraft, wherein the acquired navigation information comprises: an identity of the first aircraft; a position of the first aircraft; an altitude of the first aircraft; and a time value indicating when the position of the first aircraft was determined; an identity of the first aircraft; a position of the first aircraft; an altitude of the first aircraft; and a time value indicating when the position of the first aircraft was determined; using the acquired navigation information to determine that the first aircraft is entering a first coverage area associated with the first network node; when the first aircraft is determined to be entering the first coverage area associated with the first network node, directing a beam towards the first aircraft to establish a first link between the first network node and the user equipment; maintaining the first link between the first network node and the user equipment by transmitting beam steered, Doppler shift compensated downlink signals, and by performing beam steered reception of uplink signals, wherein beam steering is directed toward the first aircraft based on the periodically acquired navigation information, and wherein the Doppler shift compensation is based on one or more determinations of relative velocity between the first aircraft and one or more first antenna nodes associated with the first network node, and compensates for a Doppler shift experienced by the user equipment; detecting that the first aircraft will be leaving the first coverage area that is served by the one or more first antenna nodes and will be entering a second coverage area that is served by one or more second antenna nodes, and responding by causing the one or more second antenna nodes to provide a second link between the user equipment and the one or more second antenna nodes using a same cell identifier and a same frequency allocation to the user equipment as are being used for the first link.
