EGNOS目前提供基于GPS的增强服务。它允许在广泛的导航应用中获得改进的性能，特别是在民用航空领域的航空方法方面。与此同时，GPS、伽利略和其他星座正在演变，并确定了服务于欧洲用户社区的新服务，以响应新的最终用户应用需求的出现，最终呼唤EGNOS V3一代。在导航领域，EGNOS旨在支持生命安全应用，具有严格的航空性能要求。同时，应确保EGNOS服务在演进和解决方案的安全方面对最终用户的连续性，并要求解决方案具有更高的可操作性和降低生命周期成本，这意味着在运营设计上要特别注意。本文概述了如何定制和应用基于泰利斯模型的系统工程(MBSE)方法和工具来支持EGNOSV3工程目标。建立工具环境以支持基于公共设计参考的并行工程，并有助于整合和调整EGNOSV3系统架构设计和需求。由此产生的工作组织以及系统工程团队和工程领域专家(安全、安保、运营…)之间的互动提出了一种新的解决方案。最后，本文提供了基于模型的方法联合并发工程活动的经验教训和成功案例，确定了主要结果和好处。
EGNOS provides today augmentation services based on GPS. It allows getting improved performances in a wide range of navigation applications, in particular for aeronautical approaches in the civil aviation domain. In parallel, GPS, Galileo and other constellations are evolving, and new services are identified to serve European users communities, answering to the emergence of new end-users applications needs, finally calling for the EGNOS V3 generation. In the area of navigation, EGNOS is designed to support Safety of Life applications, with stringent aeronautical performance requirements. In the same time, continuity of the EGNOS service to end users when evolving and security aspects of the solution shall be ensured, and furthermore, the solution is required to have improved operability and reduced lifecycle cost, that implies to pay specific attention in operations design. This paper provides an overview on how the Thales Model Based System Engineering (MBSE) methodology and tools are tailored and applied to support EGNOS V3 engineering objectives. A tooled-up environment is set-up to support concurrent engineering on a common design reference and to contribute to the consolidation and justification of the EGNOS V3 system architecture design and requirements. The resulting work organization and interactions between system engineering team and engineering domain specialists (safety, security, operations…) are presented. Finally, this paper is providing lessons learned and success stories of a model based approach to federate concurrent engineering activities, identifying the main outcomes and benefits.
