Altitude estimation for the UAV's applications based on sensors fusion algorithm

Abstract

Altitude measurement with a high reliability is a very difficult issue not because of the sensors complexity and requirements but due to the quality of the signals and fast changing environment conditions. In this paper we focus on the problem of the vertical movement measurements of the unmanned aerial vehicles and approach to the future control algorithms implementation. Two-sensors algorithm has been proposed on the basis of the data fusion from the pressure sensor and ultrasonic range finder.
