DAC-03 Tracking Antenna Controller Operation
2-5
HDG 000.0 000.0
Heading entry mode . Used to provide “True”
Azimuth antenna position.
If the GYRO TYPE parameter is NMEA0183 data or
1:1 Synchro, you will not be able to set HDG to
any other value than it receives from the Ships
Gyro Compass. For all other acceptable Gyro
Compass input types the HDG
MUST be initially
set whenever the ACU power is turned ON. Key in
the heading value of the Ships Gyro Compass and
press
ENTER .
HDG display may be a single value, or left and
right values depending on the GYRO TYPE
parameter. When Left and right values are
displayed, left is the response from the pedestal
and right in the local input from the gyrocompass.
During subsequent normal operation, the HDG
value should automatically follow the Ships Gyro
Compass correctly (HDG value should agree with
the value observed on the Gyro Compass).
2.5.2. SAT information menus.
Main Menu Sub Menu Display Meaning
SAT 101 W THRS 1234
INA 1100 AGC 1234
Display of the current SAT information.
SAT 101 W
Satellite Longitude entry menu . Used to
calculate antenna Elevation, Azimuth and
Polarity pointing angles.
Key in the numeric longitude of the satellite
you want to target (even if it is the same
value as is presently displayed), press
N/S/E/W
to toggle the E/W hemisphere as
necessary and press ENTER .
The ACU will then calculate the Elevation,
Azimuth and Polarization that the antenna will
be driven to, based on the current SHIP
information (LAT, LON & HDG) and issue
those (AZ, EL & POL) targeting values to the
antenna. Auto-Threshold will re-set as the
antenna targets.
THRS 1234
Threshold entry mode . Default setup is
Automatic Threshold, which sets the
Threshold value to 128 counts of AGC above
the average AGC value whenever the ACU
Searches or Targets.
To manually set threshold, key in the desired
numeric value and press
ENTER .
