I can't imagine that this hasn't been discussed but I didn't find anything
in my search. I've been ignoring it since it specifically says "NON CIVILIAN
GPS." But, this just seems so weird.

!GPS 04/036 ZAU NON CIVILIAN GPS MAY BE UNREL OR UNAVBL WITHIN A
240 NM RADIUS OF 420153N/913847W AT FL400 WEF 0704250001-0712312359

That's April 25 through the end of the year, right? Non Civillian. FL400? No
higher. No lower. No block altitude. The lat/long is somewhere around Cedar
Rapids, IA, right?

That's that all about?
I'd guess that Collins is doing some high-tech testing/development work.

Happy Flying!
