3. End E SEARCH LIMIT 10 1 2 Inclined Orbit Search Pattern Some older satellites in order to save fuel to keep them exactly positioned over the Equator are in an inclined geosynchronous orbit The satellite remains geosynchronous but is no longer geostationary From a fixed observation point on Earth it would appear to trace out a figure eight with lobes oriented north southward once every twenty four hours The north south excursions of the satellite may be too far off the center point for a default box search pattern to find that satellite at all times during the 24 hour period You can configure the ACU to do a special search pattern for a satellite that is in an inclined orbit by using the following settings SEARCH INC set to the default value for the frequency band that your antenna model is currently being used for typically 15 counts SEARCH LIMIT leave this set to the default value for your antenna model SEARCH DELAY default or any number of seconds from 1 255 that you would prefer that the ACU wait before starting an automatic search SWEEP INC set to 192 if your antenna is a Series 04 or Series 06 or Series 09 Set to 193 if your antenna is a Series 97 Series 00 or Series 07 This parameter sets the sweep increment shown in the graphic above to be 8 0 degrees above below the satellite arc GYRO TYPE must NOT be set to zero SAT REF mode It is normally OFF as long as you have good gyro

In the simplest scenario if you could rotate the antenna pedestal to be in line with the bow and then rotate the home flag clamp assembly around until the trailing edge is centered on the body of the home flag sensor and tighten the clamp HFO would be set close enough for Optimizing Targeting procedure to be effective Unfortunately rarely is the equipment going to align where the clamp and sensor will be easy to access reach and see to align it this way The hex bolt heads in the plate below the Home Flag Clamp assembly are 60 degrees apart as shown in the picture on the right above and allow multiple points of view to calibrate rotation of the clamp to If you installed the ADE with the Bow reference of the radome oriented in line with the bow the antenna pedestal will be pointed in line with the ships bow when stopped at the Home Flag position on completion of initialization before it targets a satellite as shown in Figure 1 in the Electrical Calibration Procedure above In this case when the antenna stops at the home flag and is pointed in line with the Bow Home Flag Offset HFO should be set to zero and mechanical position of the metal Home Flag tab should be left at the 0 default position Any small mechanical mount error will be compensated when Optimizing Targeting is accomplished to correct for small variations of up to 5 0 degrees If the ADE is installed with the Bow reference of the radome oriented 45 to starboa
