METHOD FOR MULTI-POSITIONAL DETERMINING OF POSITION OF DECAMETRIC TRANSMITTERS Russian patent published in 2006 - IPC G01S5/04 

FIELD: radio engineering, possible use for determining position of objects using radiations of their decametric transmitters with use of two or more receiving stations (range and direction finders).

SUBSTANCE: method is based on using additional information about rules of ionosphere distribution of decametric signals. This information is considered at each receiving station when determining assumed coordinates of objects by one-positional method with use of ionosphere model. In central calculator, connected to all stations, by comparing results of physically different methods of estimation of spatial coordinates (one-positional and multi-positional) indeterminacy of unification of measurement results is removed and position of objects is determined unambiguously with use of two or more stations.

EFFECT: increased precision of determining position of a set of one-typed decametric transmitters by wider class of signals, including complex signals with low spectral density of power.
