Embodiment Construction

[0086] figure 1 An example from the prior art is shown in which simulated data are transmitted from an aircraft 100 to a ground station 102 by means of an isotropic radiator.

[0087] figure 2 One embodiment of the invention is shown. An aircraft is shown there, which is designed as an aircraft 100 and which has a first directional antenna 103 transversely or laterally on a fuselage 104 . here, in figure 2 A cross-section of the fuselage 104 is shown in the right part of , in which it can be seen that the first antenna 103 embodied as a directional antenna and the The second antenna 105 .

[0088] Furthermore, a region 108 of the fuselage facing the sky and a region 109 of the fuselage facing the ground are shown. Also shown is an angle "α" 110 . exist figure 1 The surface normal 111 of the region 108 facing the sky is likewise shown in . Furthermore, a digital transmitter unit 101 is shown, which is electrically connected to a first antenna 103 and a second antenna ...

Abstract

The invention relates to a method for digital and directed data transmission between aircraft and a ground station. Data is thereby exchanged digitally and directly, that is, instantaneously, using directed antennas between the aircraft and the ground stations. Furthermore, transmission beams are adjusted during the flight, and the directed antennas on the aircraft illuminate only areas on the ground that have a minimum clearance transversely to the flight path of the aircraft.

Description

technical field [0001] The invention relates to ground communication of an aircraft. In particular, the invention relates to a method for directional digital data transmission between an aircraft and at least one ground station, a digital transmission unit for directional digital data transmission between an aircraft and a ground station , and a communication system for directional data transmission between an aircraft and a ground station. Background technique [0002] The communication systems used today that connect an aircraft with the outside world for data transmission use omnidirectional antennas, so-called omnidirectional antennas. Owing to the low antenna gain of such an omnidirectional antenna, a high transmission power is required for the transmitter mounted on the aircraft and for the transmitter mounted on the ground. [0003] With omnidirectional antennas in or on the aircraft, transmissions from the aircraft on ground stations other than those supplied to th...
