Active development of unmanned aerial vehicles has led to their widespread use for various purposes, and magnetic prospecting is no exception. UAVs in various modifications are used in aeromagnetic surveys intended for magnetic mapping of the subsurface. This allows to solve the problems of not only aeromagnetic prospecting (identification of ore deposits, petroleum prospecting, etc.), but also of geological engineering and archeology. The advantage of using UAV lies in the cheapness and safety of the survey. Magnetic prospecting in this case is carried out with minimal financial and time costs, while the study area is limited only by the time of flight. As a rule, UAV flight time varies from 1 to 1.5 hours. This problem is due to the limitation of the energy source of the UAV. In addition, most UAVs are made from light materials such as carbon composite and aluminum, which has a positive effect on their use in aeromagnetic prospecting. However, there is little research on the impact of UAVs on magnetometers. Most of the work is devoted directly to the processing and interpretation of the results. This paper analyzes the influence of a quadcopter, an octocopter and a two-stroke combustion engine on the readings of the quantum magnetometer MMPOS-1. The impact of electric motors and a combustion engine is shown. A comparative analysis was carried out aimed at revealing the most optimal distance for a magnetometer sensor. The impact of various types of UAV is estimated, depending on their design features.
