Abstract: The invention relates to a flight guidance system for the flight support of a aircraft (1), said system comprising a plurality of fixed ground stations (4a to 4e) respectively comprising a transmitting and/or receiving unit (5a to 5e), and at least one transmitting and/or receiving unit (6) that is arranged on the aircraft (1), the transmitting units being act up to send position signals (7) and the receiving units being set up to receive said position signals (7).

Abstract: The invention relates to a method for controlling the driving dynamics of a vehicle, especially of a single-track or dual-track and vehicle. The driving dynamics of the vehicle are controlled by way of brake and/or engine intervention, notably depending on a change of the movement of the vehicle in the three-dimensional space and relative to the earth coordinate system and depending on the effective direction of gravity or the earth's gravitational pull. According to said method, the attitude or orientation and the position of the vehicle in three-dimensional space and relative to the earth coordinate system is determined by means of a satellite navigation system (GNSS) which comprises a receiver, mounted on/in the vehicle, having at least three antennas for reception of satellite navigation signals and an inertial measuring system (INS), mounted on/in the vehicle, for measuring all changes in the movement, position and/or attitude of the vehicle.

Abstract: A control device is provided for an aircraft, the aircraft having at least one undercarriage with one or more undercarriage wheels. A control mechanism interacts with the aircraft undercarriage and is configured to turn the undercarriage wheels relative to the longitudinal axis of the aircraft. The control device has an alignment unit which is connected to the control mechanism and which is configured to control the turning of the undercarriage wheels by means of the control mechanism during at least one part of the landing or take-off phase of the aircraft in such a way that the running direction of the undercarriage wheels is aligned in the direction of a fixed point which may be a corrected fixed point situated below a fixed point by a compensation angle.

Abstract: The invention relates to a device (10) for stabilizing the guidance of a vehicle (1), the vehicle (1) having at least one or two which is arranged in such a way that it can be turned relative to the longitudinal axis of the vehicle (1), and steering means that interact with the at least one wheel (2) and are designed to guide the vehicle (1) by turning the at least one wheel (2). The device (10) has a detecting unit (12), which is designed to detect an at least partial transition from static friction to dynamic friction between the at least one wheel (2) and a ground covering (3), and furthermore has a control unit (11), which, when the detecting unit (12) detects the transition from static friction to dynamic friction, is designed to turn the at least one wheel (2) by means of the steering means in such a way that the dynamic friction between the wheel (2) and the ground covering (3) changes back to static friction.
