Problems solved by technology

However, GBAS requires the construction of ground base stations, which is costly. A set of GBAS can only cover the surrounding airports within 23 nautical miles. As of 2009, there are only 8 Honeywell GBAS ground stations in the world.

Embodiment Construction

[0069] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0070] The purpose of the present invention is to propose a calculation method for generating and solving the rotating magnetic field for three-dimensional positioning in space, called the rotating magnetic field positioning method, and apply it to the positioning of the aircraft during the landing and rolling phase, which can solve the aircraft in real time. The amount of deviation from the centerline of the runway to correct it and prevent the aircraft from veering off the runway. In order to achieve the above-mentioned purpose, the present invention uses simple and independent signal sources arranged along the runway, and the signal acquisition device is placed on the n...

Abstract

The invention discloses a positioning system for a take-off deviation of an airplane, which comprises a signal generator, a signal acquisition device and a deviation positioning unit, wherein the signal generator consists of power-on solenoids vertical to each other, is arranged on an airstrip and is used for transmitting a signal; the signal acquisition device is arranged on a nose of the airplane and is used for receiving the signal transmitted by the signal generator; and the deviation positioning unit is connected with the signal acquisition device and is used for carrying out real-time resolving on the acquired signal to determine a distance that the nose of the airplane deviates the center line of the airstrip. The invention also provides a positioning method for the take-off deviation of the airplane. The positioning system of the invention has low cost. The precision of the positioning system is higher than that of the common GPS system and is equivalent to that of a GBAS system. The positioning system has simple structure, is easy to arrange, can be applied to the field opportunity airfield and is unlike the GBAS system which needs to arrange an expensive ground base station. The positioning system is self-provided with a signal source, is independent from the commonly used global positioning system and can be applied to the runways in large-scale shelters and the areas with bad satellite signals.

Description

technical field [0001] The invention belongs to the field of aerospace science and technology, and relates to an aircraft taxiing deviation positioning system and positioning method, which can be applied to positioning the position of the aircraft during the landing and rolling phase, and prevent the aircraft from deviating and rushing out of the runway. Background technique [0002] At this stage, when the aircraft rolls on the runway during the landing phase, it mainly relies on the pilot's naked eyes and the indication of the runway lights, and the pilot manually adjusts it. The positioning of an aircraft on a runway in an aircraft landing system relies primarily on onboard GPS systems, which have limited accuracy and are prone to signal jamming due to weather and obstacles including large aircraft like the A380. For this purpose, Honeywell Corporation of the United States has developed the Ground Based Augmentation System GBAS (Ground Based Augmentation System). By insta...
