Hi Bojan,
I understand you know the correct AOB of the contact at the first bearing by using the auto target function.

The angle gained by the drawing is actualy aob wright?!So if I copy it form the targets last known position It would give me the line wich would represent the targets real cours of heading.

No!
The red angle of the auxillary drawing is the AOB at your first bearingline - not the AOB at last known position.
Copy the red angle onto your first bearingline and you get courseDIRECTION - not REAL courseline!
REAL courseline is parallel to courseDIRECTION through real position from crossbearing (fifth bearing intercepts "fourth bearing").
You can compare auto target AOB at first bearingline with red angle AOB - they should be identical - more or less
To get better results:
ask for constant contact reports and speed up the time.
Start with first bearing whenever the bearings change rate is ~ 1 per minute!
A six minute index will result in an angle of ~ 6° for your A1 and A2 will be even bigger.
This should make it easy for you to construct the auxillary drawing and the "tool error" is moderated too.
In my "33° AOB drawing" A1 was 10° and A2 was 16°!
