Introduction:
The Automatic Antenna Position option provides the user with a fast and simple way to deploy the 12 Volt
Dual Axis Portable Rotor System by providing automatic True North and 0 Degree Elevation antenna system
positioning. The system consists of a Tilt Compensated 3-Axis Magnetometer and 3-axis Accelerometer that
attaches to the Left (when viewed from the back) Antenna Arm. When deploying the system, the user only
needs to set the Antenna in a Northerly position and approximately level and instruct the Hand Controller to
do an Antenna Position Calibration. When finished the system will move the antenna back to 0 degrees
True North and to 0 Degrees Elevation.
While in Remote Control mode, a move command to 0 Degrees Azimuth and 0 degrees Elevation will cause
a short re-calibration to happen. This will correct any drift inaccuracies in the system and bring the antenna
back to 0 degrees Azimuth and 0 degrees Elevation.
Specifications:
Azimuth Accuracy: +/- 4 Degrees
Elevation Ac/- 1 Degree
Installation
:
•
Power off The Az/El Rotor System
•
Remove the Left Antenna Arm and slide the mounting fixture over the end of the antenna Arm. Position such that
it does not interfere with the Arm Set Screws or rub on the Elevation unit Enclosure
•
Re-Attach the Antenna Arm, tightening the set screws
•
Adjust the sensor Arm such that it is in alignment with the attached antenna and lightly tighten the set screw
•
Plug in the 5 pin connector to the matching socket at the bottom of the Azimuth Unit. Tightening locking collar
finger tight.
•
Use Velcro straps in a few locations to mate the cable to the main Elevation cable, leaving some slack in the cable
at the top.
Initialization:
There are two required steps to initialize the Position Sensor for use: Setting your locations Declination and
Calibrating the Sensor.
To set the Declination, Power on the System while holding the “CW” button. Press the “Mode” Button to select
Magnetic Declination. Prior to this step it is recommended to look up your locations Declination, a number of web
sites can be found with your locations information.
