Accuracies of Position Fixes Obtained by GPS―V On the Use of High Stable Oscillator
抄録
In order to lengthen the usable time and evaluate the positioning accuracy of the GPS by means of two satellites, we made a measurement at three fixed stations in Japan with a GPS receiver connected with a high stable oscillator. The usable time became about four hours longer at each station. Positioning accuracy was influenced by the accuracy of navigation messages from each satellite, so that we should not use an inaccurate satellite for positioning. By avoiding an inaccurate satellite, we attained almost the same fix accuracy as the low level positioning with three satellites.
