It's very difficult to interpret what you wrote, and there seems to be an omission.

I'll use for latitude, for longitude.
And I think the problem goes like this . . .
. . Get OR if all other values are known.
And the asymmetry of the right side makes me suspect even more typos.
I can't possibly work on it until I'm sure of the original statement.
