5.1.2.4 MoveTo
The MOVETO mode is intended to provide an easy way to move the antenna to a certain position for
doing testing such as cutting antenna patterns. This mode is also useful for tuning up automatic
movements.

SET <1>AZ<2>EL<6>POL <4>START MOVE
The current azimuth, elevation and polarization angles are displayed. When the mode is first entered, the
current positions are shown as the target positions. After setting target positions and setting the desired
speed, the automatic movement may be initiated by pressing the 4 key.
<5>SENSOR:PRIMARY
The state of this field when this mode is entered will be “PRIMARY”. This means that the displayed
angles and entered targets are generated and referenced to the axis sensor that generates angles. For
instance, the typical primary elevation sensor is the electronic inclinometer.
If the mount is equipped with higher resolution sensors such as resolvers or pulse sensors, toggling the
field to “SECONDARY” will cause the display and target to change to an integer representative of the high
resolution sensor. This mode of operation allows actions such as the small movements made during
inclined orbit tracking to be simulated.
<6>LON:
This field allows the user to enter a satellite longitude. The ACU will calculate the Azimuth and Elevation
target positions and the horizontal Polarization position for a satellite at the entered longitude. The ACU
will then move the antenna to the calculated positions.
