For that purpose, the IGS orbits and clock files are considered as a priori information while ATOMIUM estimates daily station positions, hourly tropospheric zenith path delays and epoch-wise station clock synchronization errors with respect to the IGS time. In addition to its very fast operation (a daily run takes about 5 seconds by station), the mean weekly position repeatability obtained with ATOMIUM is at the level of 3.9 mm for the north, 2.4 mm for the east and 6.8 mm for the up component. If in addition, a Helmert transformation is performed to more reliably express the solution in the IGS05, then the mean weekly station position repeatabilities reach 3.1 mm for the north, 1.9 mm for the east and 5.7 mm for the up component, i.e. similar to what is presently obtained with the Bernese.
