Errors reduction in the location of objects of the radio navigation system

In the present paper, a method for improving the accuracy of the dead reckoning position of a board station based on signals from ground-based radio navigation systems is considered. In the radio navigation system, based on the radiation of the signal by the master fixed station, signals are received by the slave fixed stations with the determination of the moments of their arrival relative to their own time scales. On the other hand, based on the radio frequency radiation of signals by the slave fixed stations, signals are received by the master fixed station with the determination of the moments of their arrival relative to their own time scale. According to the measured moments of arrival of the radio frequency radiation signals, time corrections to the time scales of the slave fixed stations relative to the master fixed station are calculated. Since the time correction is calculated for a time of no more than 10 seconds, a random components are excluded due to the variability of the propagation velocity of the surface electromagnetic wave due to the variability of the environmental parameters and the parameters of the near-surface layer of the electromagnetic wave propagation area. If the calculated value of the time correction of the duration of the clock interval of the generated signal is exceeded, the moment correction (up to a clock) of the formation of the modulating code of the signal radiated by the slave fixed station is carried out and the calculated value of the time correction is corrected by the value of the previously corrected clock durations. The corrected values of the time corrections (pre-coded) are transmitted to each of the slave fixed stations as part of their navigation signals. The navigation information user receives the radio navigation signals radiated by the fixed stations, through decoding highlights information about the mismatch of time scales from the signals of the fixed stations and measures the radio navigation parameters with heightened accuracy due to compensation for the error of the out-of-sync radiation signals of the slave fixed stations of the radio navigation system.
