Description

This menu allows an offset to be inserted between the “angle”

 

from the resolver and the displayed angle in order to calibrate

 

the system for any difference between the actual antenna

 

angle and the resolver angle.

 

The actual pointing angles of the antenna are accurately

 

established and the displayed angles are set to those angles

 

using this facility.

 

Azimuth & Elevation or Polarisation are selected using menu

 

key 5.

 

The setting of the offset is done using the manual drive keys.

 

For Az & El the right and left keys offset the Az and the upper

 

and lower keys offset the El. For Pol the right and left keys

 

are used.

 

The angles displayed in the upper section of the menu screen

 

change in real time. Menu Key 6 may be used together with

 

the direction key to increase the rate of change.

 

The actual amount of offset is not displayed.

 

The offset can be returned to zero for any angle by pressing

 

the opposite keys at the same time.

 

Care should be taken to release both keys at the same time

 

otherwise another offset will be inserted.

Note

This should only be carried out at commissioning or on the

 

installation of a new resolver or if the relationship between the

 

antenna and a resolver has changed.

Caution

Inserting any offset will reset the orbit model.
