WebThe IGS Final orbits (clocks) are combined from seven (five) contributing IGS Analysis Centers (ACs), using six, largely independent, software packages (i.e. BERNESE, GAMIT, GIPSY, BAHN (Dow et al., 1999), EPOS (Gendt, et al., 1999) and PAGES (Schenewerk et …
WebOct 26, 2024 · Given the current IGS orbit accuracies, the difference between the rapid and final only impacts very long baselines. For example: a 5cm orbit error with a 20 000 000 m distance to the SV yields a 2.54e-4 m baseline error on a 100 000 m baseline. Note that the broadcast orbits accuracies are indicated to be at the one meter level. http://acc.igs.org/igsacc_final.html
