Abstract
Способ определения местоположения объекта навигации, заключающийся в излучении объектом навигации высокочастотного гармонического сигнала и приеме его в нескольких опорных радионавигационных точках с известными координатами, отличающийся тем, что с объекта навигации в течение заданного интервала времени дополнительно излучают второй высокочастотный гармонический сигнал, частота которого отличается от частоты первого высокочастотного гармонического сигнала на заданную величину, в каждой из опорных радионавигационных точек принимают этот сигнал наряду с первым, формируют из принятых сигналов сигналы разностной частоты, передают сформированные сигналы в центральный пункт обработки, где измеряют разности фаз сигналов разностной частоты, полученных из разных опорных точек, а результаты этих измерений фиксируют, все описанные действия начиная с излучения второго высокочастотного гармонического сигнала повторяют, изменив частоту второго гармонического высокочастотного сигнала таким образом, чтобы новая разностная частота увеличилась примерно на порядок, интервал же времени, в течение которого частота второго гармонического сигнала остается постоянной, выбирают достаточным для измерения разности фаз сигналов разностных частот, полученных из опорных радионавигационных точек, по окончании измерений все зафиксированные величины разностей фаз пересчитывают в координаты объекта навигации с учетом взаимного расположения центрального пункта обработки и опорных радионавигационных точек.A method for determining the location of a navigation object, which consists in emitting a high-frequency harmonic signal from the navigation object and receiving it at several reference radio navigation points with known coordinates, characterized in that a second high-frequency harmonic signal is additionally emitted from the navigation object for a predetermined time interval, the frequency of which differs from the frequency the first high-frequency harmonic signal by a given value, at each of the reference radio navigation points jumble this signal along with the first one, form the difference frequency signals from the received signals, transmit the generated signals to the central processing point, where the phase differences of the difference frequency signals obtained from different reference points are measured, and the results of these measurements are recorded, all the described actions starting from the radiation of the second the high-frequency harmonic signal is repeated by changing the frequency of the second harmonic high-frequency signal so that the new difference frequency increases by about an order of magnitude, inter At the same time, during which the frequency of the second harmonic signal remains constant, sufficient is chosen to measure the phase difference of the difference frequency signals obtained from the reference radio navigation points, at the end of the measurements, all the recorded values of the phase differences are converted into the coordinates of the navigation object, taking into account the relative position of the central processing point and reference radio navigation points.
