This program converts low-low satellite data measured by the K-band ranging system
from the GRAIL format into \file{instrument file (SATELLITETRACKING)}{instrument}.
The \config{inputfile}s contain also corrections for antenna offsets
and the so called light time correction.
The corrections can be stored in additional files in the same format as the observations.
If a phase break is found an artificial gap is created.
