Recently, we have proposed a new Global-Local Grouping method, which divides a signal charge into two parts: one provides a coarse position and the other provides a fine position. In this paper, we introduce a new Global-Local Grouping readout method, which utilizes a geometrical charge division method for cathode signals. We have fabricated an ultra-long microstrip detector whose sensitive length is 640 mm. Test measurement with neutron beam showed good global and local position resolutions, that were estimated to be 32mm and 1.2mm, respectively.
