(4) The automatic antenna alignment calibration can be carried out at up to four different

aircraft headings. Out of the available headings, it is required to do only one automatic

alignment calibration while the aircraft true heading is toward one of the preferred directions.

NOTE: The values displayed in Figure 5-13 will change depending on the location

and attitude of the aircraft.

(5) The recommended values are dependent on the radome and these values are calculated

by the KANDU based on the input from the aircraft IRS and the selected satellite coordinates

and the APM configuration data. The Auto Alignment application automatically presents

the four true headings to the operator when a target satellite is selected from the

“recommended” target which is also location dependent. There is a recommended tolerance

range for these headings which is dependent on the radome and configured in the APM

configuration data.The chosen recommended true headings are used so that the radome

has consistent performance (i.e. no large changes in curvature) over the area being used

during alignment.

NOTE: It is advised not to do the automatic antenna alignment during rains with heavily

clouded sky.

(a) The antenna alignment should be performed only after completion of system power

up. The health status of each LRU should be checked on the GUI, and there should

be no display of system muting due to Initialization. Only then should the Initiate

button be pressed on the Antenna Alignment GUI page.

(b) The JetWave™ MCS-8562 Terminal uses the following input parameters during

the antenna alignment procedure:

Aircraft IRS data-

- OAE IMU data

- RSSI as reported from the Modman.

antenna calibration process, all LRUs of the JetWave™ MCS-8562 Terminal need

to be powered up with aircraft IRS system functioning and providing valid inputs.

The GUI page indicates the IRS status.

(d) Once the aircraft is aligned to within the tolerance range of any of the recommended

aircraft heading, the grayed out on the “Initiate” button will be changed, indicating

the system readiness to commence the antenna alignment process.

(e) Watch the GUI Antenna Alignment Calibration progress status bar until complete.

(f) On successful completion of the antenna calibration, the status changes to

“Complete”.

NOTE: If for some reason the Calibration procedure fails, the operator will be

given the opportunity to repeat the procedure. This may require several

attempts to finalize and confirm the offsets.
