Hi Trevor,

Matthias Jelen did a test on the Trimble Thunderbolt here:


So we're all quite confident that the TBolt 1PPS and 10 MHz will be glitch-free. Mark Sims fixed his LH program so even the date & time will be correct. Still, the more tests the better, and the more thorough the better. Thanks for posting your results. The rest of us are envious that you own or have access to a GPS/GNSS simulator.
