Graham, Merlin,

Nice discussions that could have been avoided by me if I thought of asking Mr. Nestorovic before 2 minutes ago. Sorry, but that's Titian: sometimes very very very very late. But in italy they say: better late then never!

So hear is the answer:

Mr. Nestorovic said that the whole system IS time alligned (1 m in front of the satellites).  He said this discussion about time allignments was already there 20 years ago and 20 years ago he has done it. All the components (crossover and drivers) are especially made  for the time allignment.
