Embodiment Construction

[0026] The World Wind-based 4D track display method provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] figure 1 It is a flow chart of the 4D track display method based on World Wind provided by the present invention.

[0028] Such as figure 1 As shown, the 4D track display method based on World Wind provided by the present invention comprises the following steps carried out in order:

[0029] (1) The S1 stage of sorting out the aircraft flight dynamic data handed over by the air traffic control command system:

[0030] The air traffic control command system distributes the aircraft flight dynamic data required for display to the display subsystem through the local area network. According to regulations such as air traffic control radar and control center facility coordination handover data specification (MH / T 4008-200) and European surveillance data handover standard (SUR.ETI...

Abstract

The invention discloses a 4D trajectory displaying method based on World Wind. The 4D trajectory displaying method based on World Wind comprises the following steps of disposing flight dynamic data of an aircraft; converting projection coordinates of the aircraft so as to obtain the projection position; introducing control airspace GIS data so as to obtain an airspace background; combining the projection position of the aircraft and the airspace background so as to obtain the projection position of the aircraft with the combination of the airspace background; and displaying the flight dynamic data of the aircraft in the form of comprehensive information and the like. According to the method disclosed by the invention, the three-dimensional airspace background of a display subsystem is rendered by utilizing a World Wind platform; the dynamic information of the aircraft is displayed by adopting a transparent target layer, and the position of the aircraft at the target layer is consistent with the three-dimensional airspace background by adopting a space conversion mode, so that relatively intuitive airspace dynamic information can be provided for managers, and the effectiveness and reliability of air traffic control can be improved.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a four-dimensional track display method for an air traffic control command system. Background technique [0002] Aircraft four-dimensional (4Dimensional, referred to as 4D) track is a method of accurately describing the spatial position (longitude, latitude and altitude) and time of aircraft operation in the form of space and time. System, referred to as NEXTGEN) and one of the important supporting technologies of the European Sky Integrated Air Traffic Control Research (Single European Sky ATM Research, referred to as SESAR) program. The operation based on 4D trajectory can significantly reduce the uncertainty of aircraft trajectory, and improve the safety and utilization of airspace and airport resources. At the same time, 4D trajectory is of great significance in flight conflict research, airspace planning, trajectory planning, flight simulation, air traffic control support ...
