Are there specs for any of the Russian GPSDO's
With phase resolution around 1000 times better than a Tbolt, they should be

I see that Meinberg have just announced a GPS/Glonass LanTime unit. It can
work either one or the other source or a combined mode. Would like to get my
hands on one.

We are looking to offer Glonass enabled versions of our Jackson Labs Tech
GPSDOs (Firefly-II series) by Q1 next year.

If sufficient interest exists.
