No time lost…portable precision time in your pocket.

Nanosynchronization of multiple transducers requires a common clock source, such as the time signal from GPS.  But when no GPS signal is available, synchronization is still possible, assuming you have a very stable clock, where an atomic clock is as … Continue reading
