The Tracker Calibration Wizards
Your tracker is easily calibrated by running one of the tracker calibration wizards, as described below.
Before running the wizard, ensure that the tracker’s linkage is adjusted so that the tracker is centered (pointing to 0 degrees as shown in Figure 8),
and the pan servo is also centered, so it can move back and forth the same amount in either direction. Note that you must always use this same
linkage adjustment at the field, so that the tracker will pan to the same angles that the EagleEyes will learn in the wizard. In other words, the pan
servo position must correspond with the same pan angle at the field that it learns in the wizard steps below.
Your tracker is calibrated by running the appropriate calibration wizard based on how far your tracker tilts.

If your tracker TILTS 90 degrees (from horizontal to vertical) select the “Tracker Cal Wizard 180dg Tilt” menu item to calibrate the tracker.

If your tracker TILTS a full 180 degrees (from horizontal to horizontal) select the “Tracker Cal Wizard 180dg Tilt” menu item to calibrate the
tracker.
After selecting the appropriate wizard, you will be prompted to pan and tilt the tracker to the specified angles.
You will use your radio’s ELEVATOR stick to move the servo corresponding to the axis being calibrated (don’t
manually move the servos!).
Servo movement speed is proportional to the degree of elevator stick deflection, so moving the stick farther will
speed up the servo movement, and less deflection will allow you to precisely adjust the position.
MAKE SURE that you don’t allow the tracker’s servos to move too far during calibration, as this can destroy the
servos!
Here are the steps to follow in the wizards:
Pan tracker to -90 (CCW)/Mode: Use the elevator stick to move the tracker’s PAN servo Counterclockwise, until the antenna is pointing exactly -90
degrees (precisely to the LEFT, if you are standing behind the tracker). Toggle the Mode switch when it is in the correct position.
Pan tracker to max CCW/Mode: Use the elevator stick to move the tracker’s PAN servo almost as far as it will go Counterclockwise (to the LEFT),
but not so far as to cause the pan servo to bind. Toggle the Mode switch when it is in the correct position.
Pan tracker to +90 (CW)/Mode: Use the elevator stick to move the tracker’s PAN servo Clockwise, until the antenna is pointing exactly +90 degrees
(precisely to the RIGHT, if you are standing behind the tracker). Toggle the Mode switch when it is in the correct position.
Pan tracker to max CW/Mode: Use the elevator stick to move the tracker’s PAN servo almost as far as it will go Clockwise (to the RIGHT), but not
so far as to cause the pan servo to bind. Toggle the Mode switch when it is in the correct position.
Tilt tracker to 0(horiz)/Mode: Use the elevator stick to move the tracker’s TILT servo until the antenna is pointing at 0 degrees (horizontal). In other
words, the antenna should be tilted as it would be when the model is on the ground. Toggle the Mode switch when it is in the correct position, or if
your tracker doesn’t support tilt.
(for 90 degree tilt trackers) Tilt tracker to 90(vert)/Mode: Use the elevator stick to move the tracker’s TILT servo until the antenna is pointing at 90
degrees (vertical). In other words, the antenna should be tilted as it would be when the model is directly overhead. Toggle the Mode switch when it
is in the correct position, or if your tracker doesn’t support tilt.
(for 180 degree tilt trackers) Tilt to 180(backward)/Mode: Use the elevator stick to move the tracker’s TILT servo until the antenna is pointing at
180 degrees (backwards). In other words, the antenna should be tilted as it would be when the model is directly behind the tracker. Toggle the Mode
switch when it is in the correct position, or if your tracker doesn’t support tilt.
Tracker calibrated!/Click Mod: The tracker should now be correctly
calibrated. Choose angles in the “Pan Test” and “Tilt Test” menu items
if desired, to confirm that the tracker is moving correctly.
Calibrating Your Tracker using the Vector
Software
Calibrating your tracker with the Vector software is very similar to the
onscreen menu calibration steps above, so please read those steps first.
To calibrate the tracker with the software, click the “Calibrate Tracker”
button on the “EagleEyes and Data Logging” tab. Then, the tracker
calibration wizard (shown at right) will appear. Follow the instructions
in the wizard. Instead of moving the tracker with your elevator stick, the
wizard’s buttons are used.
