METHODICAL ERROR OF LOW ALTITUDE ALTIMETERS AND POSSIBILITIES OF ITS IMPROVEMENT

Abstract

This article is focused on the present state in the field of the accuracy of measurement of the real height of the aircraft above the terrain with a radioaltimeter. Authors deal with the analysis of beat frequency generation and also with the reasons of formation of the methodical error of radioaltimeter. On the base of those knowledge and findings this article also implies the solution and the attitudes to the improvement of the accuracy of radioaltimeter by reducing of the methodical error.
