Tri-band (L1/L2/L3) antenna modules АМ415 have been developed consisting of a patch slot leaky wave antenna with the right-hand circular polarization and a low-noise amplifier. Their accuracy characteristics have been studied. It has been shown that when taking measurements in the L1 frequency band using GLONASS/GPS combined constellation the root-mean square deviation (RMSD) of the positioning accuracy of the second and third module АМ415 relative to the first one is 2,2 mm in the horizontal plane and 1,7 mm in the vertical plane. RMSD of the positioning accuracy with yaw, roll and pitch angles does not exceed 9 angular minutes at a distance of 0,7 m between the centers of three antenna modules and it is up to 4 angular minutes at a distance of 2 m. The antenna modules АМ415 are designed for the high accuracy positioning using GLONASS/GPS signals.
