The difference between their
average positions is 3.28 cm in latitude, 1.44 cm in
longitude and 0.91 cm in altitude. 2drms against the
average points is 2.63 cm and 3.60 cm, and S.D. in
altitude is 2.08 cm and 2.83 cm, respectively. The low
rate of ‘Fix’ solution by Kawasaki GPS-based Control
Station is supposed to be due to the excess of data
transmission delay over 2.0 s, which is observed
approximately every other second. It seems that the
transmission delay should be within 2 s in order to get
‘Fix’ solution by Trimble 4000SSi’s. There must be
some technical problems to be solved in the
communication system from Kawasaki GPS-based CS
through Shinyokohama MCA Base Station.
