导航中的完整性与可信度：从误差表征到运行保障
Integrity and Credibility in Navigation: From Error Characterization to Operational Assuran
AI总结：
该研究区分导航完整性与估计器可信度的定义，通过假设场景分析不同异常情况对二者判断的影响，明确评估需涵盖事件、主张可信性及信息适用性。
AI中文摘要：
导航完整性与估计器可信度利用误差和不确定性信息解决不同问题。本文视角区分实际定位误差与报告的统计表征，将完整性定义为在指定运行要求下控制危险未预警使用风险，将可信度定义为通过证据使用和建模过程对不确定性或风险主张的正当性论证。三个假设场景展示精度下降、不确定性报告矛盾及危险事件如何导致不同的可信度与完整性判断，最终评估需明确发生了什么、报告主张为何可信、信息是否满足预期运行需求。
英文摘要：
Navigation integrity and estimator credibility use error and uncertainty information to address different questions. This perspective distinguishes actual positioning error from reported statistical characterizations, formulates integrity as control of hazardous unwarned-use risk under the requirement of a specified operation, and describes credibility as the justification of an uncertainty or risk claim by its evidence usage and modeling process. Three hypothetical scenarios show how deteriorated accuracy, a contradicted uncertainty report, and a hazardous event can lead to different credibility and integrity judgments. The resulting assessment asks what happened, why the reported claim should be believed, and whether the information is sufficient for the intended operation.
