The invention discloses a multi-level airspace planning method based on a spherical diamond discrete grid, and the method comprises the following steps: 1, carrying out the conversion of airspace coordinate information from an equal latitude and longitude coordinate system to a spherical rectangular coordinate system in an airspace management system according to a spherical latitude and longitude coordinate system and a regular icosahedron spherical diamond discrete grid; step 2, carrying out regular icosahedron rhombic grid subdivision; step 3, establishing an airspace coordinate global coding system, performing global positioning coding on the airspace coordinate points, and completing multi-level airspace planning based on the spherical diamond discrete grid; and step 4, in the airspace management system, managing the aircrafts in the governed airspace according to the global positioning codes in the step 3. According to the method, the problem that the flight safety is finally influenced by the inconsistent flight intervals caused by the inconsistent area representation of the airspace model in the grid representation can be effectively solved.
本发明公开了一种基于球面菱形离散格网的多层级空域规划方法,包括以下步骤:步骤1、在空域管理系统中,根据球面经纬度坐标系,结合正二十面体球面菱形离散格网,进行空域坐标信息由等经纬度坐标系向球面直角坐标系转换;步骤2、进行正二十面体菱形格网剖分;步骤3、建立空域坐标全球编码系统,对空域坐标点进行全球定位编码,完成基于球面菱形离散格网的多层级空域规划;步骤4、在空域管理系统中,依据步骤3中所述的全球定位编码,对所管辖空域内的飞行器进行管理。本方法可以有效解决空域模型在格网表征中存在的面积表征不一致,进而导致飞行间隔不一致,最终影响飞行安全的问题。
