Hej Björn,

They replaced all their GPS receivers, that failed over a span of 24 hours.

I need to be updated on that. I fear the last page is not written on that
affair.

Sadly enought they don't seem too keen to test one of their old GPS receivers
with the GPS simulator. I think the whole thing was setup the wrong way. It
wheren't in their best interest to do that part of the aftermath, so they where
not too keen to pay that simulation time while their economy got strained by
the unexpected need to buy new GPS receivers and install those (a nation wide
effort). I think we need to have another approach than that to get the
simulations we want. There are a few other things that went wrong that we take
between four eyes Björn.

Cheers,
Magnus
