摘要

本文重点介绍了概率模型检验在飞行器制导卫星定位系统中的应用。在引入基于PRISM模型检查器的形式化方法的基础上，利用支持并发性、不确定性和移动性建模的过程代数——概率π微积分，建立了基于GNSS的特定飞行定位系统模型。之后，我们将模型编码为PRISM语言。然后，我们分析与底层系统的可靠性和整体性能相关的可用性属性。我们的研究目的是使用PRISM来协助工业设计师和GNSS的开发人员。

Availability Analysis of Satellite Positioning Systems for Aviation Using the PRISM Model Checker

This paper highlights an application of probabilistic model checking to satellite positioning systems for aircraft guidance. After introducing our formal approach based on using the PRISM model checker, we built a model of a global navigation satellite system (GNSS) based positioning system for a specific flight in the probabilistic π-calculus, a process algebra which supports modelling of concurrency, uncertainty, and mobility. After that, we encode our model into the PRISM language. We then analyse the availability properties that relate to the dependability and overall performance of the underlying system. The aim of our research is to use PRISM to assist industrial designers and developers of the GNSS.
