Реализация алгоритма RAIM в среде MatLab

Abstract

Целью работы является реализация и исследование эффективности работы алгоритма автономного контроля целостности спутниковой навигационной информации в ÑƒÑÐ»Ð¾Ð²Ð¸ÑÑ Ð½ÐµÐ³Ð°Ñ‚Ð¸Ð²Ð½Ð¾Ð³Ð¾ влияния ÑÐ»ÑƒÑ‡Ð°Ð¹Ð½Ñ‹Ñ Ð¸ ÑÐ¸ÑÑ‚ÐµÐ¼Ð°Ñ‚Ð¸Ñ‡ÐµÑÐºÐ¸Ñ Ð¿Ð¾Ð³Ñ€ÐµÑˆÐ½Ð¾ÑÑ‚ÐµÐ¹ Ð¸Ð·Ð¼ÐµÑ€ÐµÐ½Ð½Ñ‹Ñ Ð¿ÑÐµÐ²Ð´Ð¾Ð´Ð°Ð»ÑŒÐ½Ð¾ÑÑ‚ÐµÐ¹, а также при воздействии Ð¿Ñ€ÐµÐ´Ð½Ð°Ð¼ÐµÑ€ÐµÐ½Ð½Ñ‹Ñ Ð¿Ð¾Ð¼ÐµÑ . Ð’ результате исследования был разработан алгоритм автономного контроля целостности спутниковой навигационной информации, который базируется на сравнении значений невязок с пороговым значением. Вычислены значения порога для различного количества спутников и различной дисперсии ошибок псевдодальностей. Для оценки эффективности разработанного алгоритма проведено моделирование в среде MatLab для различного местоположения приемника, различного числа Ð²Ð¸Ð´Ð¸Ð¼Ñ‹Ñ ÑÐ¿ÑƒÑ‚Ð½Ð¸ÐºÐ¾Ð² и различной дисперсии ошибок псевдодальностей.

The aim is to study the implementation and effectiveness of the satellite navigation information algorithm autonomous integrity monitoring under the negative influence of random and systematic errors of the measured pseudo-ranges, as well as under the influence of jamming. The study was designed algorithm autonomous integrity monitoring satellite navigation information, which is based on a comparison of residual value to a threshold value. The values of the threshold for the number of different satellites and different dispersion of pseudo errors. To evaluate the efficiency of the developed algorithm has been simulated in the MatLab environment for a different position of the receiver, a different number of visible satellites and the dispersion of various pseudo errors.
