the search pattern is reached, the MXP will retarget the antenna to the calculated Azimuth and Elevation
point.
If the desired signal is found (AND network lock is achieved in the satellite modem) at this position, or
anywhere within the search pattern, the MXP will terminate search and go into Tracking mode. If the desired
signal is not found the MXP will wait SEARCH DELAY, then target the antenna to start point shown in the
graphic above and begin the search pattern again. This cycle will repeat until the desired satellite signal is
found or the operator intervenes.
12.1.3. Sky Search Pattern
If the ship does not have a gyro compass to use as a heading input to the MXP, you may manually key in the
actual heading of the vessel and then re-target the desired satellite, every time you need to re-target a
satellite, or configure the MXP to do a “No Gyro Search Pattern”.
Initially the antenna will go to the “Start” relative azimuth position at the calculated elevation. Then the
antenna will search up 450 degrees in azimuth, search up one Search Increment in elevation, search down
450 degrees in azimuth, search down two Search Increments in elevation, etc until Search Limit is reached.
When the end of the search pattern is reached, the MXP will retarget the antenna back to the start point
shown in the graphic below.
If the desired signal is found (AND network lock is achieved in the satellite modem) at this position, or
anywhere within the search pattern, the MXP will terminate search and go into Tracking mode. If the desired
signal is not found the MXP will wait SEARCH DELAY seconds and then begin the search pattern again. This
cycle will repeat until the desired satellite signal is found or the operator intervenes.
12.2. TX Pol select
Is used to select the transmit polarity of the C-Band Linear/Circular selectable feed, or the Ku-Band linear feed,
whichever is currently installed.
12.3. Band select
Controls the band selection of the selected LNB (X-Pol or Co-Pol ) on the Ku-Band linear feed ONLY. This setting works
in conjunction with the X-Pol / Co-Pol selection setting.
12.4. X-Pol / Co-Pol select
Selects the desired (X-Pol or Co-Pol ) on the Ku-Band linear feed ONLY. This setting works in conjunction with the
band selection setting.
