Multi Hz is usually a feature of the chipset.  If ti is Antares/Ublox it
might be able to do 5Hz with WAAS or 10Hz without.

(I have 3 Wintec Bluetooth/USB modules that use antares/ublox that I used
because they were 10Hz, and they weren't that much more expensive and that
was a few years ago).
(Even my Skytraq 20Hz isn't that much more expensive).

But that might be a good question - would WAAS improve the timing?

If there is a "first batch": available, I'd sign up to be on it.
