Satellites now form a core component for space based systems such as GPS and GLONASS which provide location and timing information for a variety of uses. Such satellites are designed for operating on orbit to perform tasks and have lifetimes of 10 years or more. Reliability, availability and maintainability (RAM) analysis of systems has been indispensable(More)
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(More)
Zonal safety analysis (ZSA) is important to system safety analysis, and is especially required during the development of aircrafts. As the ZSA method in present specifications and standards is not well-enough designed to implement, an improved ZSA scheme was put forward here. In the new scheme, the connotation of ZSA method was clarified, and the method was(More)
With the aid of the Finite State Machine (FSM) and formal verification, a framework of updated Functional Resonance Analysis Method (FRAM) is proposed to refine operation guidelines as such and hence improves manufacturing processes by reducing risks of unqualified products during manufacturing operations. Firstly, the FRAM is used to model a manufacturing(More)
