ABSTRACT

The development of modern space systems requires the collaboration among several national and international space organisations. Along with this complexity and diversity come progressively increasing challenges with managing the associated requirements, properties, emergent behaviours, and integration risks. Collaborative and distributed simulation is one technology being applied to address these challenges. A notable example of this is the well-established standard for distributed simulation, the IEEE 1516-2010 – High Level Architecture (HLA). To enable and ensure a-priori interoperability for complex space systems simulations and foster international collaboration, the Simulation Interoperability Standards Organization (SISO) formed a Product Development Group (PDG) to develop the Space Reference Federation Object Model (SpaceFOM). This article presents the SpaceFOM standard describing the principal design elements that compose it along with a set of design patterns introduced to deal with common issues in distributed simulation and to pursue extensibility, interoperability, and robustness.

摘要

现代空间系统的发展需要多个国家和国际空间组织之间的合作。随着这种复杂性和多样性的出现，在管理相关需求、属性、紧急行为和集成风险方面面临的挑战也越来越大。协作和分布式仿真是用于解决这些挑战的一种技术。这方面的一个显着例子是完善的分布式仿真标准，即 IEEE 1516-2010 – 高级架构 (HLA)。为了实现和确保复杂空间系统模拟的先验互操作性并促进国际合作，模拟互操作性标准组织 (SISO) 成立了一个产品开发组 (PDG)，以开发空间参考联邦对象模型 (SpaceFOM)。
