摘要: 在对空域空间有限元的相关研究中,构建空域空间的网格标识系统,是将信息技术应用于空域管理、推进空域数字化的重要基础。在美军全球区域参考系统和通用地理位置参考系统基础上,提出了一种同时具备标识平面和立体空间位置能力的参考系统。通过在地球表面以上特定高度之下的空间内,建立一种递归剖分策略方法,将空域空间划分为若干空间网格,不同尺度下的网格既是一种地理空间位置参考系统,也是一种组成空域的基本空域体,以此实现空间位置参考与空间位置标定的混合表达,为开展空域数字化管理提供底层模型。

Abstract: At present, in the related researches of airspace spatial finite element, the construction of a grid identification system for airspace space is an important foundation for applying information technology to airspace management and promoting airspace digitization. Based on the US military’s global regional reference system and general geographic location reference system, this paper proposes a reference system that has the ability to identify both plane and three-dimensional spatial positions. By establishing a recursive system in the space below a specific height above the earth’s surface, the airspace space is divides into several spatial grids. Grid at different scales is not only a geographic spatial position reference system, but also a basic airspace body that composes the airspace, which means to realize spatial position reference and spatial position calibration. The mixed expression of airspace provides an underlying model for the development of digital airspace management.

Key words: airspace spatial identification model, spatial recursive division, basic airspace unit, finite element, spatial grid coding
