The Navigation Equipment of Consumers (NEC) working on signals of the global navigation satellite systems (GNSS) of GLONASS and GPS, finds more and more broad application as a part of various objects, including in artillery. For mobile artillery pieces, rocket artillery and mortars the most effective is NAP application with a mode of definition of spatial orientation, so-called "goniometric NAP" (UNAP). The antenna system of UNAP consists of several antenna modules (AM) carried in space that allows by results of measurement of a difference of phases of signals of the bearing frequency of the navigation spacecrafts (NS) at AM exits, with high precision to define a difference of a course of signals of NS between AM and to provide measurement by an interferometrichesky method of spatial orientation (corners of a course (roving), pitch and a list) with a margin error in units of angular minutes. In article approaches to metrological providing the goniometric navigation equipment of the consumer of GLONASS/GPS, applied as a part of objects are considered, allow to solve problems of updating of the equipment on object, and also periodic checking of UNAP in field conditions as a part of object directly in dislocation places forces of specialists of exit test laboratory.
