GPS Data inside SSA Convention Hall

Hi,

I have a technical question. Next week at the SSA Convention many vendors
(myself included) will have many soaring instrument demos on display. It
would be great if they could be locked onto GPS satellites, but that is not
likely inside the convention hall. I imagine the roof is made of metal.
The moving map displays will display more interesting information when
locked onto satellites. Also, the all the FLARM units in the room would
show up on the moving map displays - but only if the FLARMs and the moving
map displays are locked-onto GPS satellites.

Is there a technical solution to that issue? Could a receiver be mounted
somewhere that receives, amplifies or re-directs and rebroadcasts the GPS
signals for use inside the hall?

I have no idea if that is possible, easy or difficult.

Any thoughts?

I imagine it is too late to get that working for the SSA Convention this
year, but it doesn't hurt to ask.

Best Regards,
