Re: Accuracy of tracking programs



Hi all

I have a similar question but mine is regarding "squint"
I'm using WinOrbit and as far as AO-40 is concerned, it indicates a low
squint (about 4 degrees).  I noticed in one of the postings it was mentioned
that AO-40 was at about 30 degrees.
How can I make sure the attitude information is correct in the program?
Also having some "blue screen" problems with it!!
Anythoughts???

Enjoy the postings and hope to be on AO-40 eventually...!!!!!  :-)

Cheers
