В режиме гирокомпасирования начальный угол курса бесплатформенной инерциальной навигационной системы (БИНС) определяется на основе данных акселерометров и гироскопов, измеряющих проекции вектора гравитационного ускорения и вектора угловой скорости вращения Земли на оси связанной системы координат в начальном неподвижном режиме работы БИНС. Из-за неизбежного наличия нестабильности смещения нуля и случайных шумов в сигналах акселерометров и гироскопов требуется длительное время для получения достаточного объема данных датчиков, чтобы достичь требуемой точности определения полезных измеряемых значений методом усреднения. Поэтому, чтобы сократить время режима гирокомпасирования, необходимо использовать методы обработки данных для снижения нестабильности смещения нуля и случайных шумов в полученных от инерциальных датчиков БИНС сигналах.Цель работы. Разработка метода подавления случайных шумов и уменьшения нестабильности смещения нуля в сигналах инерциальных датчиков, благодаря чему сокращается время режима гирокомпасирования БИНС при обеспечении требуемой точности определения ее начального угла курса.Материалы и методы. Используется модель авторегрессии (англ. autoregressive – AR) для построения математической модели случайных шумов в сигналах датчиков, затем эти шумы фильтруются путем использования фильтра Калмана типа SKURF (англ. Square-Root Unscented Kalman Filter) с применением Sage-окна (англ. Sage window Square-Root Unscented Kalman Filter – SW-SRUKF).Результаты. Математическая модель случайных шумов инерциальных датчиков в неподвижном режиме. Алгоритм подавления случайных шумов. Результаты обработки реальных данных в виде рисунков и таблиц для апробации эффективности предложенного метода.Заключение. Предлагается метод шумоподавления для снижения нестабильности смещения нуля и случайных шумов акселерометров и гироскопов БИНС путем комплексирования AR-модели и SW-SRUKF. Корректность и эффективность предложенного метода подтверждена результатами обработки реальных данных с инерциальных датчиков. Полученные результаты значимы для сокращения времени начальной выставки БИНС в режиме гирокомпасирования.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. In the gyrocompassing mode, the initial heading angle of a platformless inertial navigation system (PINS) is determined based on the data obtained from accelerometers and gyroscopes that measure the projections of the gravitational acceleration vector and the Earth’s angular velocity vector on the axes of the body coordinates system in the PINS initial stationary mode. Due to unavoidable circumstances, such as bias instability and random noise in the accelerometer and gyroscope signals, much time is required to obtain the sufficient amount of sensor data for achieving the necessary accuracy of useful measurement values by the averaging method. In this context, in order to reduce the time of the gyrocompassing mode, data processing methods should be used to eliminate the bias instability and random noise in the signals received from PINS inertial sensors.Aim. To develop a method for suppressing random noise and reducing bias instability in the signals of inertial sensors, thereby reducing the time of the gyrocompassing mode of PINS and providing for the required accuracy of its initial heading angle determination.Materials and methods. An autoregressive (AR) model was used to simulate random noise in the measured sensor signals followed by its filtering using a Sage-window square-root unscented Kalman filter (SW-SRUKF).Results. A mathematical model describing random noise in the PINS inertial sensors in the stationary mode was derived. A methodology for suppressing random noise was proposed. The effectiveness of the proposed method was tested on actual data, with the results presented in the form of figures and tables.Conclusion. A method for eliminating the bias instability and random noise of PINS accelerometers and gyroscopes was proposed based on AR model and SW-SRUKF. The accuracy and effectiveness of the proposed method was confirmed by processing actual inertial sensor data. The results obtained are significant for reducing the initial alignment time of a PINS in the gyrocompassing mode.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инерциальный датчик</kwd><kwd>случайный шум</kwd><kwd>фильтр Калмана типа SRUKF</kwd><kwd>Sage-окно</kwd><kwd>интегрированная модель авторегрессии – скользящего среднего</kwd><kwd>начальная выставка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inertial sensor</kwd><kwd>random noise</kwd><kwd>square-root unscented Kalman filter</kwd><kwd>Sage window</kwd><kwd>autoregressive integrated moving average model</kwd><kwd>initial alignment</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">Боронахин А.
