Javad LGG100 with GPS/GLONASS L1 is available from around $4500.
Javad GGD112T with dual freq is available from around $8200.

The GG-16 (GPS/GLONASS L1) should be available for sub $1k.

Galileo will use the ITRF. (WGS84 has been converging towards ITRF in
the latest WGS84 revisions) They are now said to be identical down to
the cm level.

It is possible to do GPS or GLONASS in the same receiver channel. See
