Hi Bruce,

I seem to remember that the old Austron 2200 series GPS (2200 and 2201) had
a myriad of output data available on all sorts of GPS parameters. 

Will dig around my archives and check.

Subject: [time-nuts] Earth rotation angle parameters via GPS?

The GPS interface control document IS-GPS-200D defines message type 32 on
page 145 (Figure 30-5) and pages 175-178.
The message contains the parameters necessary to calculate UT1 (Earth
rotation angle) when UTC is known.
Does anyone know of a readily available GPS receiver that makes these
parameters accessible to the user?

Bruce
