This program converts low-low satellite data measured by the K-band ranging system
from the GRACE SDS format (KBR1B or LRI1B) into \file{instrument file (SATELLITETRACKING)}{instrument}.
The \config{inputfile}s contain also corrections to 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.
For further information see \program{GraceL1b2Accelerometer}.
