Abstract
Status of the upgrade of the tagging system of KEDR experiment at VEPP-4M is described. Triple-GEM detectors have been added to eight coordinate stations of the system. These detectors will improve momentum resolution of the system and will allow effective rejection of the background of single Bremsstrahlung events. Main parameters of the triple-GEM detectors have been measured at the cosmic ray setup. Efficiency reaches 98% and spatial resolution in the direction of the beam orbit plane is 73 μ m (standard deviation).
