"Navigation Principles and System"is a professional course with civil aviation characteristics.As the equipments for the ground based radio navigation system are very expensive

it is difficult for the students to have direct access to these devices.Thus this paper introduces MATLAB language into the teaching of "Navigation Principles and System"to simulate the ground based radio navigation system by using MATLAB software

from which the students can further understand the principle of these navigation equipments and build a solid foundation for their engagement in avionic equipment repair

technology management and research.
