Abstract
The purpose of the work is to study the methods of estimation of navigation accuracy using information of azimuthal navigation systems.
The general task of this course work is to evaluate the accuracy of lines of position and location of aircraft using information of azimuth navigation systems.
Radio navigation systems are assigned to ensure navigation software for the tasks of navigation solving by radio technical methods. Among them, the important is to determine the current value of the position of the aircraft and line position. It is up to the accuracy of all navigation options depends on the accuracy and reliability of the tasks of navigation.
