FIELD: radar ranging and radio navigation.
SUBSTANCE: invention relates to radar ranging, in particular, to determination of location of ground targets by ground-based spatially distributed radio navigation system (RNS), containing transmitters of RNS reference stations, ground receiver, in which for illumination of targets signals of transmitters are used RNS. Transmitters of reference stations RNS with known coordinates, navigation signals are emitted, which are scattered by ground targets with unknown coordinates, ground receiver with known coordinates synchronized with transmitters of reference stations RNS, by signals scattered by ground targets, distance Rnm "n-th transmitter – m-th target – receiver", wherein for the space of the possible location of the targets viewing the coordinates of the virtual ground target are given, for each n-th transmitter (n = 1, 2, …, N) detected in the receiver, forming the M equations corresponding to the M targets, from these equations selecting the equation corresponding to the target with the number 
, for which module of difference between virtual and measured distance "n-th transmitter – m-th target – receiver" will be minimum, generating sums of minimum values of difference modules corresponding to virtual targets 
, after calculating sums of difference moduli Δk coordinates M of targets are selected coordinates corresponding to M minimum values of these sums of modules, wherein set of M vectors, each of which includes N measurements 
, providing minimum Δk, is the result of primary identification of position measurements in ground spatially distributed RNS.
EFFECT: identification of position measurements and location of several ground targets by radio navigation system based on measurements of sums of distances from ground targets to transmitters of reference station RNS and ground receiver, coordinates of which are known.
