This article presents information on the design and use of unmanned aerial vehicles with adescription of the design solutions of individual elements. The purpose of this work is to analyze the designof the UAV, review the main parts, analysis and comparison of technologies for measuring altitude andstabilization of drone flight, description of UAV control processes based on modified stabilization in airspace sensors and altitude regulators. Developments in the areas of height measurement and UAVstabilization are presented and described at the current time. The general design of a UAV based on a ISSN 2221-3805. Електротехнічні та комп’ютерні системи. 2021. №34 (110)Автоматизовані електромеханічні системиquadcopter is described. The existing variants of altitude sensors, which are necessary for drones of specialdesign, are considered. 3 existing systems are described - barometric, ultrasonic and visual positioning.RADAR, LIDAR and LADAR systems are among the systems that are not found on civil drones, because theyvery have a complex design and are quite expensive for simple drones. Possibilities of their use as UAValtitude sensors, advantages and disadvantages. RADAR systems is ToF systems, which measure time offlight transmission by electromagnetic waves. LIDAR and LADAR are optical height meters, which worksimilarly systems RADAR. Two variants of drone flight stabilization, use of regulators on the basis of neuralnetworks and traditional systems with the use of PID-regulators are considered. The work of such regulatorsis described, graphs are given, which show the difference between the set and real angles of deviation of thepitch 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 ofaltitude measurement and flight stabilization is envisaged. Building a mathematical model using sensors andregulators described here to study their real real behavior in the field. Integration of LADAR, LIDAR andRADAR systems as the additional measurement systemsones for special and civil UAVs
