The algorithm for the definition of a navigating vector of the consumer was offered and it is based on the condition and Kalman filter variables in strapdown inertial navigating system which uses the quaternion approach to the rotary motion description. Calculation accuracy characteristics of the given algorithm are done. There was investigated the influence of frequency of data receipt on accuracy of location.
Предложен алгоритм определения навигационного вектора потребителя, использующий сигма-точечный алгоритм фильтра Калмана в бесплатформенной инерциальной навигационной системе с использованием кватернионного подхода к описанию вращательного движения. Выполнены расчеты СКО погрешности оценок местоположения потребителя. Изучено влияние скорости поступления данных на точность оценки местоположения.
