which leads to pointing inaccuracies. Setting the value too high may actually slow the process down
as the AAQ is forced to correct for frequent over-shoot of the target position.

Plateau Peaking Coarse Azimuth
Velocity
4
Float
0.02 to 30.0
Azimuth velocity in degrees/sec for
coarse peaking.
Plateau Peaking Coarse Elevation
Velocity
4
Float
0.02 to 30.0
Elevation velocity in degrees/sec for
coarse peaking.
Plateau Peaking Fine Azimuth Velocity
4
Float
0.02 to 30.0
Azimuth velocity in degrees/sec for
fine peaking.
Plateau Peaking Fine Elevation
Velocity
4
Float
0.02 to 30.0
Elevation velocity in degrees/sec for
fine peaking.
Plateau Peaking is a function used only with certain types of modem systems, where the signal
feedback reaches a limit over the course of a scanning sequence. The differential in degrees is
measured during this limit and a pointing “center” is calculated for the acquisition solution.

Polarization Dwell Iterations
4
Unsigned
1 to 100
Number of peaking iterations to pause for look for
signal changes.
Polarization Peaking Step
4
Float
0.0 to 60.0
Width in degrees to scan during a pol peaking
function.
Scan Polarization Velocity
4
Float
0.01 to 60.0 (deg/sec)
Pol scanning maximum velocity used in scanning
movements.
Polarization Peaking Enabled
4
Choice
"No", "Yes"
If set to “Yes”, then the pol will be peaked after fine
peaking
Polarization Peaking is an automated process that may be employed only on specially equipped
and supported linearly polarized AvL antenna systems. This new AAQ feature is currently
implemented only on satellite systems that utilize a feedback signal metric generated by the NOC
and provided to the AAQ via the forward satellite link and the terminal’s Modem (Hughes HX).
