В качестве беспилотного летательного аппарата использовался электрический гексокоптер DJI Matric 600Pro. Схема проведения съемки заключалась в следующем: маршрут во время полета состоял из трех параллельных залетов (основных профилей) и одного пересекающего залета (перпендикулярный профиль). Расстояние между соседними параллельными залетами составляло 100 м. Пересекающий профиль был необходим для проведения увязки основных профилей относительно друг друга. Каждый полевой день полетные задания строились таким образом, чтобы профили перекрывались с соседними вылетами величиной не менее 100 м и траектория движения совпадала с предыдущим вылетом. Для оптимизации процесса для двух соседних вылетов выбиралась одна точка взлета/посадки. Максимум за одну съемку в течение 20–25 мин беспилотное воздушное судно с магнитометром покрывало профиль величиной, равной 1,25 км. Максимальная величина полета (от момента взлета до момента посадки) не превышала 6–6,5 пог. км. Рассмотренная в работе методика позволила покрывать 45 пог. км на протяженном участке даже в сложных погодных условиях (дождь и порывы ветра 8–12 м/с). Итоговая среднеквадратичная погрешность данной съемки составила ±4,7 нТл. В результате проведенной съемки было получено три профиля со значением индукции магнитного поля на протяженном участке. В итоге наблюдалась хорошая корреляционная зависимость между аэромагнитной съемкой с данными блокового строения фундамента (по данным геоморфологического анализа) с локальной компонентой кристаллического фундамента. Алтунино-Шунакский разлом уверенно проявился в магнитном поле в виде положительной аномалии с амплитудой ≈60 нТл.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of the study is to survey the magnetic field induction on the Romashkinskoye oil field (Republic of Tatarstan, Russia) using an unmanned aerial vehicle over the profile of 68 km 320 m. A DJI Matric 600Pro electric hexacopter was used as an unmanned aerial vehicle. The survey scheme was as follows: the mission route consisted of three parallel flights (main profiles) and one crossing flight (transverse profile). The distance between adjacent parallel flights was 100 m. The intersecting profile was necessary to connect the main profiles. The flight assignments of each field day were built to overlap the profiles by at least 100 m by the nearby flights and make the flight trajectory coincide with the one of the previous flight. To optimize the process one takeoff / landing point was selected for two nearby flights. During one 20-25 min survey the maximum profile covered by the unmanned aerial vehicle was 1.25 km. The maximum flight distance (from the takeoff moment to the landing) did not exceed 6–6.5 linear kilometers. The methodology considered in the article made it possible to cover 45 linear kilometers over a long span even in adverse weather conditions (rain and wind gusts of 8–12 m/s). The resulting root mean square error for this survey was ±4.7 nT. The survey conducted allowed to obtain 3 profiles with the magnetic field induction magnitude over an extended section. A good correlation was registered between the aeromagnetic survey and the data on the block structure of the basement (according to geomorphological analysis data) with the local component of the crystalline basement. Altunino-Shunak fault has clearly manifested itself in the magnetic field as a positive anomaly with an amplitude of ≈60 nT.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>беспилотный летательный аппарат</kwd><kwd>аэромагниторазведка</kwd><kwd>геофизика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>unmanned aerial vehicle</kwd><kwd>aeromagnetometry</kwd><kwd>geophysics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Пат. № 172078, Российская Федерация, МПК B64C 39/02.
