HEADING         : 
     PRIMARY    : heading from gpshead
     CORRECTION : heading correction from ashtech

POSITIONS       : gps positions from gpsnav

CALIBRATION     : original transducer orientation: 44.80
                  transducer depth: 3.0
                  (check original processing parameters)
                  additional rotation 0
                  final transducer angle is:
                       (original transducer angle) - (rotate_angle)

COMMENTS        : gaps in heading correction?
                  scattering layers?
