RESEARCH THE ACCURACY OF ALGORITHMS OF STRAPDOWN INERTIAL ORIENTATION SYSTEMS

Abstract

The problems of comparing the accuracy of known algorithms of strapdown inertial orientation systems by computer V-test. A method according to the generalized representation of the drift error of the algorithm from step survey sensors in the form of dimensionless quantities.The effect on the accuracy of the algorithm step size survey type integrable equation, the type of algorithm, the number of polling steps in one step of integration. Two algorithms are proposed with precision at least an order of magnitude greater than that of known algorithms. The conclusions on the effectiveness of V-test for the analysis of the accuracy of the algorithms

Розглядаються питання порівняння точності відомих алгоритмів бесплатформенних інерціальних систем орієнтації (БІСО) за допомогою комп'ютерного V-тестування. Запропоновано спосіб узагальненого представлення залежності дрейфу похибки алгоритму від кроку опитування вимірювачів у вигляді безрозмірних величин. Досліджено вплив на точність алгоритму величини кроку опитування типу рівняння, що інтегрується, виду алгоритму, кількості кроків опитування в одному кроці інтегрування. Запропоновано два алгоритми з точністю принаймні на порядок більшою, ніж у відомих алгоритмів. Зроблено висновки про ефективність V-тестування для аналізу точності алгоритмів

Рассматриваются вопросы сравнения точности известных алгоритмов бесплатформенных инерциальных систем ориентации (БИСО) с помощью компьютерного V-тестирования. Предложен способ обобщенного представления зависимости дрейфа погрешности алгоритма от шага опроса измерителей в виде безразмерных величин. Исследовано влияние на точность алгоритма величины шага опроса типа интегрируемого уравнения, вида алгоритма, количества шагов опроса в одном шаге интегрирования. Предложены два алгоритма с точностью, по крайней мере, на порядок большей, чем у известных алгоритмов. Сделаны выводы об эффективности V-тестирования для анализа точности алгоритмов
