IQUICK START GUIDE INTRAC-305

A suggested quick start procedure is given below:

1/ Before modifying system make a note the antenna pointing angles from the old tracking

system.

2/ Perform any recommended resolver mounting bracket modifications.

3/ Connect INTRAC-305 in place of Andrew APC300 and check that the Fitted Options

(Home>Function>System Setup>Fitted Options) (Manual page 39) are set correctly. Note

that the resolvers used with the APC300 system were normally x2 resolvers which would

require the x2 setting in the fitted options.

4/ Select Station Coordinates (Home>Function>System Setup>Station Coordinates) and

ensure that latitude is in correct hemisphere (North or South). You only need to enter the

correct station co-ordinates if you intend to use IESS-412 or Norad ephemeris data.

5/ Select Date and Time (Home>Function>System Setup>Date & Time) and enter the correct

time and date (in UT (GMT)). This is only strictly necessary if you intend to use IESS-412 or

Norad ephemeris data, but most users prefer to set the time correctly anyway.

6/ Select beamwidth (Home>Function>System Setup>Az & El Beamwidth) and set the receive

3 dB beamwidths of your antenna.

7/ Now ensure drive direction feedback is correct.

Select Manual on INTRAC . (Home>New Mode>Manual/Stow) Note displayed Az angle.

Command drive Right. Check if displayed angle increases or decreases.

Command drive left. Check if displayed angle increase or decreases.

Continue driving left until displayed angle has returned to the previously noted angle.

The angle should have increased while driving right and decreased while driving left. If it did

the opposite then the resolver sense is not correct and will need correcting. By bringing the

antenna back to the original displayed angle we have maintained the angle reference.

Note the displayed Elevation angle and repeat the operation for Elevation. Commanding Up

should give an increasing angle, Down a decreasing angle. If you found the opposite then

you will need to change the elevation resolver sense. Make sure you return the antenna to

the same elevation position (reading).

8/ If either resolver senses required changing then Select Fine Tune (Home>Function>System

Setup>Fine Tune) and change the required senses on the first screen. Then press EN to

continue and adjust the fine tune offsets so that the angle display reads the correct angles (

the ones you noted in step 1).

9/ Now check that Manual drive drives the angles in the expected direction. At this point you

can also check that the physical direction on motion of the antenna is also correct, but this

will be correct if the original installation was correct.

10/ Connect the beacon signal.

If an IBR-L is fitted and an L-band beacon is available connect this to the RF input on the

rear panel of the INTRAC. Select the correct frequency and check that a valid beacon level

is displayed. Manually peak the antenna to maximize the beacon level and check that the

beacon does not overload (24.9 dB displayed).
