Study on Safety & Protection Ability of GNSS Receiver from the View of Main Materiel System

Abstract

The global navigation satellite systems (GNSS) is used more and more widely in military and civilian, but because of low sending power of GNSS signal, and other weakness, the safety and protection related issues have attracted wide attentions. However, most literatures about this were just qualitative enumeration or only focused on the navigation performance itself. This work studied this question from the view of the main materiel system that GNSS served for. We analyzed the impacts of GNSS receiver’s safety & protection ability on the operational utility of main materiel system based on a mathematical model. First of all, a mathematical function which contains several protection related parameters was used to describe the issues, followed with detail quantitative methods for those parameters. Then a case study was shown to demonstrate the application of the model proposed before. Based on the case study, it appears that the method has great potential and applicability to safety & protection ability analysis of GNSS.
