На основе исследования вероятности наличия прямой видимости в условиях сверхплотного распределения опорных станций радиодоступа и транспортных средств, а также существующих математических моделей-прототипов позиционирования, разработана новая имитационная модель построения траектории транспортного средства для оценки соответствия требованиям по точности оценки координат на примере сценария приоритетного проезда перекрестков. В имитационной модели реализованы процедуры сбора первичных угломерных и дальномерных измерений опорными станциями, полученными от транспортного средства, для последующей вторичной обработки с использованием расширенного фильтра Калмана, в результате чего в реальном времени строится траектория движения транспортного средства. В отличие от существующих моделей-прототипов, разработанная в настоящей работе имитационная модель позволяет производить оценку соответствия заданным требованиям и другим спецификациям в зависимости от текущих условий наличия прямой видимости, а также точности сбора первичных угломерных измерений, определяемых установленной на опорном устройстве антенной решеткой. Результаты имитационного моделирования согласуются с известными оценками моделей-прототипов и подтверждают возможность достижения точности до 1 м для сценария управления дорожным движением при погрешности определения угла прихода сигнала в 2°.</p></abstract><trans-abstract xml:lang="en"><p>This work is devoted to the study of mathematical models of vehicle positioning in ultra-dense V2X / 5G radio access networks using the extended Kalman filter. Based on the study of the probability of line-of-sight availability in the conditions of ultra-dense distribution of reference radio access stations and vehicles, as well as existing mathematical prototype positioning models, a new simulation model for constructing the trajectory of a vehicle has been developed to assess compliance with the requirements for the accuracy of coordinate assessment on the example of the scenario of priority passage of intersections. The simulation model implements the procedures for collecting primary angle and rangefinder measurements by reference stations received from the vehicle for subsequent secondary processing using the extended Kalman filter, as a result of which the vehicle trajectory is built in real time. In contrast to the existing prototype models, the simulation model developed in this work makes it possible to assess compliance with the specified requirements and other specifications depending on the current conditions of line-of-sight availability, as well as the accuracy of collecting primary angle measurements determined by the antenna array installed on the support device. The results of simulation are consistent with the known estimates of prototype models and confirm the possibility of achieving an accuracy of up to 1 m for a traffic control scenario with an error in determining the angle of arrival of a signal of 2 °.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>позиционирование</kwd><kwd>сверхплотные сети 5G</kwd><kwd>дальномерные и угломерные измерения</kwd><kwd>расширенный фильтр Калмана</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vehicle to everything</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">Фокин Г.А., Кучерявый А.Е.
