9.2. Manually Calibrating Targeting
1. Access the Satellite Search screen
2. Assure that your Ship Latitude & Longitude
(under ship position) and Heading (in the
banner) settings in the MXP are correct.
3. Target the desired satellite by selecting it
from the drop down list. You will see a
message “Acquiring Satellite Signal…Please
Wait” displayed.
4. Watch the Azimuth and Elevation values
displayed in the center area of the banner
and prepare to click the Track OFF button.
When targeting the antenna will initially drive to an
elevation position that is 8 degrees above (or below
if the elevation is greater than 83 degrees) the
actual calculated position that the satellite should
be at. After azimuth and polarization also finish
driving, the elevation will drive to the actual
elevation of the satellite.
5. As soon as the elevation drives (up or
down) 8 degrees click the Track OFF
button and record the Azimuth and
Elevation positions displayed in the banner
(these are the Calculated positions).
6. Click Track ON button and allow the
antenna to search, acquire and track the
desired satellite.
As this happens you will see “Satellite Signal Found”
and “Modem Lock: LOCKED” messages displayed.
7. After the antenna has been tracking for
several minutes, record the Azimuth and
Elevation positions of the antenna (these
are the Peak positions).
8. Subtract the Peak Positions from the
Calculated Positions to determine the
amount of Trim which is required.
9. Access the Reflector Configuration page.
