Hi The TBolt is a very unique design. It directly uses code phase information against the OCXO. The net result is really no different than the “correction message” approach, but it is a different implementation. Since you can’t *buy* the guts of a TBolt to strap into a DIY GPSDO, it’s not generally part of a “I want to build a GPSDO from scratch” conversation.
