Abstract:

Ground-based area navigation is an important part of the implementation of area navigation,and the operation of ground-based area navigation must evaluate the coverage and accuracy of the DME facilities,in this way to ensuring the effectiveness and safety. This article describes the basic calculation principle of the ground-based area navigation system,the network structure,the system design method and the function of system,such as data management,analysis and evaluation of navigation performance,data exchange,and so on. This paper also introduces an application case which combined the specific airport. The purpose of this paper is that giveing a solution to solve the problem of ground-based regional navigation performance assessment.

Key words: RNAV, navigation performance evaluation, signal coverage, update area, accuracy assessment
