Embodiment Construction

[0019] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0020] This method for extracting track cruising segments from aircraft three-dimensional position sequences comprises the following steps: (1) reading aircraft pressure altitude data and recording the time of the data; (2) combining China's airspace level allocation scheme, using Aircraft pressure altitude data, analyze and calculate the altitude where the aircraft is currently flying; (3) compare the pressure altitude data of three adjacent points in time one by one for each calculated aircraft pressure altitude data of the same altitude layer, and cut out the level flight The segment sequence of the increase and decrease of the aircraft pressure altitude in the segment is obtained to obtain the level flight segment sequence of the aircraft cruising segment, wherein each level flight segment sequence contains the star...

Abstract

The invention discloses a method for extracting the cruise section of a flight path from a three dimensional position sequence of an air craft, including: (1) reading atmospheric pressure height data of the air craft and recording the time of the data; (2) calculating the flight level at which the air craft is located currently; (3) cutting off climbing and descending sequence section in level flight section to obtain the level flight sequence section of the cruise section; (4) reading GPS longitude and latitude data and recording the time of the data; (5) intercepting the GPS longitude and latitude sequence into direct flight sequence section and cutting off turning sequence section to obtain the direct flight sequence section of the cruise section of the air craft; (6) solving an intersection of the level flight sequence section and the direct flight sequence section over time; calculating the difference of atmospheric pressure height data with lower sample rate in the sequence duration of which meets the duration requirement to extract the cruise section of the flight path is extracted. The method realizes analysis and processing on the three dimensional position sequence of the air craft, effectively removes climbing, descending and turning sections and extracts the cruise section of the flight path.

Description

technical field [0001] The invention relates to a data processing method for a three-dimensional position sequence of an aircraft, in particular to a method for extracting track cruising segments from the three-dimensional position sequence of an aircraft. Background technique [0002] With the rapid development of our country's national economy, the volume of air traffic continues to grow, making it difficult for the existing air traffic management system and technology to meet the needs of development. In order to promote the sustainable development of air traffic, improve the existing management system, and solve the bottlenecks that restrict the development of air traffic control such as airspace congestion, ICAO is constantly introducing new concepts and technologies for air traffic operations. [0003] Drawing on the international high-efficiency altitude allocation scheme and the application of high-precision navigation technology, my country has successfully implemen...
