Web12 apr. 2024 · It is also known that PPP does not require a reference station and determines the coordinates of a station on the International Terrestrial Reference Frame (ITRF) . Unfortunately, a limiting factor in PPP is the long convergence time (<30 min in static PPP) required for ambiguity resolution and obtaining stable results [ 7 , 8 ]. WebSince the Bar廿gada (Guam) station was not transferred to Japan and was terminated in 1993, it was decided to change the configuration of the stations (Fig. 1 ) .
