摘要

The analytic approach proposed by N. Divine for meteoroid flux calculation has been applied to develop a tool providing flux and spatial density data resulting from space debris. The tool is based on simple structured input data describing the size distribution as well as the distributions of orbital elements of single population phases (e.g. catalogued objects, paint flakes) or objects on particular classes of orbits such as GTO. The input data may either be provided as discrete (tabled) distribution data or by means of functional forms. The tool combines the advantages of deterministic approaches, e.g. the MASTER Analyst application (high resolution flux data), with the advantages of analytical approaches (simplicity, CPU time efficiency). Shortcomings of the Divine approach, e.g. the assumption of symmetric population distribution, have been identified and patched. In the course of the upgrade of ESA's Meteoroid and Space Debris Terrestrial Environment Reference model (MASTER) the kernel of the new tool has been established as the so called MASTER 'Standard Application' replacing the former MASTER 'Engineering Application'. This paper presents the implementation philosophy of the tool. A discussion of the model capabilities is followed by a comprehensive comparison to the MASTER Analyst application. Finally, a number of promising applications and extensions offered by the simple structure and CPU time efficiency of the tool is addressed by this paper.

Divine提出的流星通量计算分析方法已被用于开发一种工具，该工具可提供由空间碎片产生的通量和空间密度数据。该工具基于简单的结构化输入数据，该数据描述了尺寸分布以及单个填充相（例如，分类物体，油漆薄片）或特定类别的轨道（如GTO）上的轨道元素的分布。输入数据可以作为离散（表格）分布数据提供，也可以通过功能形式提供。该工具结合了确定性方法的优势，例如MASTER Analyst应用程序（高分辨率通量数据），具有分析方法的优势（简单性，CPU时间效率）。 Divine方法的缺点，例如已经确定并修补了对称人口分布的假设。在升级ESA的“流星和空间碎片地面环境参考模型”（MASTER）的过程中，已建立了新工具的内核，即所谓的MASTER“标准应用程序”，取代了以前的MASTER“工程应用程序”。本文介绍了该工具的实现原理。在讨论模型功能之后，将与MASTER Analyst应用程序进行全面比较。最后，本文讨论了该工具的简单结构和CPU时间效率所提供的许多有前途的应用程序和扩展。
