The accuracy Df a few centimeters oan be easily obtained in 2drms of the horizontal positions by R. TK − GPS positioning . It is necessary , however , to provide tho carrier phase data丘o 皿 a reference station looated at a known position, to a user rcceiver . It is hard to purchase the expensive GPS receiver for RTK − GPS . So , the RTK − GPS users in Japan have desired the develop 皿 e 皿t of a 皿 ore flexible , wider and less expensive carrier phase data dissemination service fbr a long time . In
