Беспилотные летательные аппараты (БПЛА) все чаще используются в военных и научных исследований. Некоторые миниатюрные БПЛА полагаются полностью на глобальной системе позиционирования (GPS). GPS уязвим для случайного или преднамеренного вмешательства что может привести к его сбою. Для БПЛА, полагающихся исключительно на GPS для навигации такое событие может быть катастрофическим. В настоящем документе предлагается расширенный подход фильтра Калмана для оценки местоположения БПЛА, когда его GPS-соединение потеряно. Приводится альтернативное использование частичного фильтра. В конце делается вывод о необходимых направлениях дальнейших научных исследований.</p></abstract><trans-abstract xml:lang="en"><p>Unmanned aerial vehicles (UAVs) are increasingly used in military and scientific research. Some miniaturized UAVs rely entirely on the global positioning system (GPS) for navigation. GPS is vulnerable to accidental or deliberate interference that can cause it to fail. It is not unusual, even in a benign environment, for a GPS outage to occur for periods of seconds to minutes. For UAVs relying solely on GPS for navigation such an event can be catastrophic. This article proposes an extended Kalman filter approach to estimate the location of a UAV when its GPS connection is lost, using inter-UAV distance measurements Increasing the accuracy of coordinate’s determination is one of the most crucial tasks of the modern UAV navigation. This task can be solved by using different variants of integration of navigation systems. One of the modern variants of integration is the combination of GPS/GLONASS-navigation with the extended Kalman filter, which estimates the accuracy recursively with the help of incomplete and noisy measurements. Currently different variations of extended Kalman filter exist and are under development, which include various number of variable states [<xref ref-type="bibr" rid="cit1">1</xref>]. This article will show the utilization efficiency of extended Kalman filter in modern developments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>беспилотный летательный аппарат</kwd><kwd>математическое моделирование</kwd><kwd>фильтр Калмана</kwd><kwd>GPS</kwd><kwd>контроль</kwd><kwd>навигация</kwd><kwd>интеграция</kwd><kwd>геометрия движения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Kalman filter</kwd><kwd>GPS</kwd><kwd>coordinates UAV</kwd><kwd>mathematical modeling</kwd><kwd>aerial vehicle</kwd><kwd>visual odometry</kwd><kwd>projective geometry</kwd><kwd>control</kwd><kwd>navigation</kwd><kwd>integration</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">Макаренко Г.
