Abstract
Изобретение относится к области радионавигации, может быть использовано для определения угловой ориентации объектов по сигналам космических аппаратов глобальных навигационных спутниковых систем и направлено на повышение точности определения угловой ориентации объекта в условиях наличия систематической погрешности измерения фазовых сдвигов принимаемых сигналов. Указанный технический результат достигается предлагаемым способом, который обеспечивает определение угловой ориентации по результатам одного или нескольких разновременных измерений фазовых сдвигов сигналовкосмических аппаратов (>4). Способ реализуется подбором целочисленных неоднозначностей измеренных значений фазовых сдвигов, определением неизвестных значений ориентации объекта и разности группового времени запаздывания, исключением избыточных значений угловой ориентации путем проверки на соответствие априорным данным, проверкой оставшихся значений с использованием сигналов дополнительных космических аппаратов. Искомое значение угловой ориентации определяется на основе критерия максимального правдоподобия.The invention relates to the field of radio navigation, can be used to determine the angular orientation of objects from signals of spacecraft global navigation satellite systems and is aimed at improving the accuracy of determining the angular orientation of an object in the presence of a systematic error in measuring the phase shifts of received signals. This technical result is achieved by the proposed method, which provides for the determination of the angular orientation from the results of one or several multi-temporal measurements of the phase shifts of spacecraft signals (> 4). The method is implemented by selecting the integer ambiguities of the measured phase shift values, determining the unknown values of the object orientation and the group delay time difference, eliminating the excess angular orientation values by checking for a priori data compliance, checking the remaining values using signals from additional spacecraft. The desired value of the angular orientation is determined on the basis of the maximum likelihood criterion.
