USAL settings out of sync

Hi friends,

It looks my motorised dish have moved by wind as my USAL settings does not bring signals on any of the sats. Therefore, I have setup all the sats using the postioner setup.

From the USAL parked position, I have to click 8 to 10 time 'move West' to get best signals within the postioner setup fine movement option.

I was reading, I can tweak my longitude or latitude settings to get the USAL working.again.

Any idea what should I change latitude or longitude? 1 click West is equal to how many degrees?

My fake coordinates are as below
Longitude 003.320 West

Latitude 051.521 north

Just want to know which number I need to tweak to get the signals.
