3 In the Antenna configuration window, input the Baseline length 2.5 metres if the
standard Antenna Bracket is used, otherwise this length has to be measured
manually with 1 cm accuracy and this value entered. For the Antenna orientation
input an approximate value or input zero if you are uncertain. For the Height
difference input an approximate value. Then click on the
Calibration wizard
button to prepare the calibration.
4 In the Antenna calibration wizard – Page 1 Input Parameters, Step 1 check that the
baseline length has been entered correctly.

5 In Step 2 input 120 minutes (two hours) as the calibration period and the logging
interval as 10 seconds. Log the calibration data to the file "Seapath.cal" on a
preferred folder on the PC.
6 Before pressing Next and start logging of Seapath GNSS, it is recommended to
start recording data of the vessel reference heading on another PC or by manual
readings. When logging of the reference heading has started, click
Next in order
to proceed to page 2 Processing.
7 The progress of the calibration process is then shown on the screen with a
graphical presentation of the measured data for the Seapath heading, the gyro
compass (if connected), the antenna baseline length and the height difference.
