as pointed out earlier, while we know Chelton has their own
GADHARS in a familiar blue box with the same names we know
on their IDU I and III.

it sounds like from
http://www.aero-news.net/index.cfm?ContentBlockID=423a7277-4c85-4405-9290-53b63a27fdc2

"Chelton's new compact digital air data and attitude/heading reference system,
(ADAHRS), along with Chelton's latest technology Beta 3 GPS/WAAS (Wide Area
Augmentation System) receiver."

it sounds like there is a Chelton branded certified LPV ready GPS.
