FIELD: radio engineering and communications.
SUBSTANCE: invention relates to the field of engineering of radio engineering positioning means and can be used, for example, to control the movement of mobile objects. This result is achieved due to the fact that in the ranging method, the generation of two continuous low-frequency oscillations in each measurement station is performed with simultaneous generation in each measuring station high-frequency oscillations, the frequency of which is known, but in each measuring station has its own, the radiation of these oscillations through the transmitting antennas, the reception of these oscillations in both transponders, the shift to a known low frequency, which for each transponder has its own and is generated by a low-frequency transponder generator, reradiation, secondary reception and allocation of combinational components with these frequencies with the subsequent measurement of phase difference of these combination components and signals of local low-frequency generators. After that, the frequencies of the high-frequency generators of each measuring station are reversed and measurements similar to those described above are made. As a result, four phase differences are obtained, which determine four ranges from each of the two measurement stations to each of the two transponders.
EFFECT: reducing the frequency resource used while maintaining the update rate of the position data of the object.
