METHOD OF LOCATING CONSUMERS OF NAVIGATION INFORMATION OF SATELLITE NAVIGATION SYSTEMS Russian patent published in 2014 - IPC G01S5/14 

FIELD: radio engineering, communication.

SUBSTANCE: method involves determining coordinates of consumers navigation information with an M-channel receiving device, which receives navigation radio signals from S satellites of satellite navigation systems; forming a spatial array of the expected coordinates of the object of consumers of navigation information and measuring, in the receiving device, relative velocities between the phase centre of the antenna of the receiving device and coordinates of each of the S satellites of the satellite navigation systems using measured Doppler frequency shifts, from which normalised values of relative velocities or accelerations are obtained and normalised calculated values of relative velocities or accelerations between expected positions of coordinates of the receiving device located in the nodes of the spatial array and each of the S satellites of the satellite navigation systems are subtracted, wherein coordinates of consumers of navigation information are determined iteratively by searching for a global minimum of the mean-square deviation of the difference in measured and calculated values in nodes of the formed spatial array and reducing the size of said spatial array at each iteration.

EFFECT: high accuracy of real-time global location of consumers when the navigation equipment of the consumer is operating in offline mode.
