Median Orbit Repeatability (see table below): 6.0 cm
This week, we add five new candidate global stations. As with other sites,
these sites are given the opportunity to participate in the orbit and clock
solution as the global site distribution varies. The following nominal
coordinates were assumed:
X (m) Y (m) Z (m)
HILO (Hilo, HI, USA) -5446001.8115 -2533417.4802 2138468.2071
HNLC (Honolulu, HI, USA) -5506798.7611 -2240049.7833 2302720.2972
MAUI (Maui, HI, USA ) -5466068.8855 -2404328.3191 2242127.3144
MSKU (Franceville, Gabon) 6198407.1698 1494056.7354 -180399.5311
PARC (Punta Arenas, Chile) 1255992.4258 -3622975.1314 -5079719.3782
Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated. (For
geographical reasons, they may not have been used in any case.)
