Abstract

Article is devoted for new formation methods of signals of the global navigating satellite systems that connected with application of overlay coding. Two possible variants of such application are considered: formation of identical and different overlay codes in the signals concerning with different satellites. Research of correlation properties of both variants of application of overlay codes on an example of the codes used in Galileo system is conducted.
