The article deals with the problem of researching the influence of the magnetic field caused by unmanned aerial vehicle navigation equipment. The possibilities of using magnetometric information in modern aviation are analyzed. The process of integrating inertial sensors and magnetometric devices for determining moving vehicle orientation is shown. The tested unmanned aerial vehicle, and attitude and heading reference system, which is used for magnetic heading determination, are described. Features of the experimental test and sequence of its stages are represented. The results of the experiment are given in a graphical way. The analysis of the obtained results is represented.
