MODE OF DEFINITION OF THE COORDINATES OF MOBILE STATIONS Russian patent published in 2007 - IPC H04B7/26 

FIELD: the invention refers to the field of radio technique and may be used in the position finding systems of the mobile stations of communications systems.

SUBSTANCE: the mode includes evaluation of a relative time delay by way of measuring divergence of the incoming time of the signal from a mobile station relatively to the reference time scale formed at measuring the time structure of the signal of the base station whose location is considered known, the distance from the base station to the mobile station is defined on the basis of time delay transmitted in the signal of the base station, two relative time delays in two standing positions of the measurer with known coordinates are evaluated, two hyperbolic lines of position defined by two relative time delays are calculated, the hyperbolic lines of positions with taking into consideration the distances from the base station to a mobile station are corrected, the coordinates of the mobile station are defined by way of calculating the point of intersection of two hyperbolic lines of position.

EFFECT: definition of the coordinates of mobile stations of communications systems with frequency-time division of channels.
