Abstract: This article presents information on the design and use of unmanned aerial vehicles with a description of the design solutions of individual elements. Developments in the areas of height measurement and UAV stabilization are presented and described. The general design of a UAV based on a quadcopter is described.

The existing variants of altitude sensors, which are necessary for drones of special design, are considered. 3 existing systems are presented - barometric, ultrasonic and visual positioning. RADAR, LIDAR and LADAR systems are among the systems that are not found on civil drones. Possibilities of their use as UAV sensors, advantages and disadvantages. RADAR systems include ToF systems, signal transmission by electromagnetic waves. LIDAR and LADAR are optical height meters.

Two variants of drone flight stabilization, use of regulators on the basis of neural networks and traditional systems with the use of PID-regulators are considered. The work of such regulators is described, graphs are given, which show the difference between the set and real angles of deviation of the pitch and yaw, which allows to evaluate the advantages of using each of regulators.

As a future study, the development of a prototype quadcopter for the study of the considered systems of altitude measurement and flight stabilization is envisaged. Build a mathematical model using sensors and regulators described here to study their real real behavior in the field. Integration of LADAR, LIDAR and RADAR systems as the main ones for UAVs.
