With the increasing number of navigation satellite constellations from multiple service providers, an emerging concept for receiver avionics is being developed which will significantly improve the current, widely available operations based on the classical Receiver Autonomous Integrity Monitoring (RAIM). This emerging concept, called Advanced RAIM (ARAIM), is envisioned to eventually provide a worldwide approach capability for Localizer Performance with Vertical Guidance (LPV). One major architectural change of ARAIM from RAIM is introduction of the Integrity Support Message (ISM), which is a set of parameters representing the statistical characterization of the core navigation constellation performance. The ISM values will be periodically updated and used as a priori information in the ARAIM user algorithm. Therefore, it is critical to broadcast ISM values that would provide optimal ARAIM performance balanced between the margins of integrity, continuity, and availability. In this paper, we analyze the sensitivity of ARAIM performance to potential ISM mischaracterization.

高级 RAIM 性能对完整性支持消息值中的错误表征的敏感性

随着来自多个服务提供商的导航卫星星座数量不断增加，正在开发一种用于接收器航空电子设备的新兴概念，它将显着改善当前基于经典接收器自主完整性监测 (RAIM) 的广泛可用的操作。这一新兴概念称为高级 RAIM (ARAIM)，旨在最终为具有垂直引导 (LPV) 的定位器性能提供全球进近能力。与 RAIM 相比，ARAIM 的一个主要架构变化是引入了完整性支持消息 (ISM)，这是一组表示核心导航星座性能统计特征的参数。ISM 值将定期更新并用作 ARAIM 用户算法中的先验信息。所以，广播 ISM 值以提供在完整性、连续性和可用性之间平衡的最佳 ARAIM 性能是至关重要的。在本文中，我们分析了 ARAIM 性能对潜在 ISM 错误表征的敏感性。
