Precision Timing
dpGPSDO
It all starts with a nano-second
Our differential phase GNSS disciplined oscillator is a new technology that fixes a hidden limitation in most precision timing GPSDO solutions. Most commodity 'disciplined' oscillators are, in fact, ONLY frequency stable.
dpGPSDO produces a reference clock that is both 1) frequency stable and 2) phase aligned to the GNSS 1 PPS.
In fact, the conventional GPSDO reference clock phase deviation is unknown, inconsistent, and on the order of many tens of nano seconds. To put this in perspective a single nanosecond of precision results in about one foot of positional accuracy. Or more simply stated, without the dpGPSDO, expect to achieve a football field of precision.
With the dpGPSDO expect sub-meter precision on commodity oscillators and better when upgrading from the VCTCXO to an OCXO
Prolific Effects' dpGPSDO was designed from the ground up to meet sub-meter timing requirements while remaining procurable and inexpensive at scale. Furthermore, our dpGPSDO is the ONLY precision timing device that enables in-line manifold calibration for interferometry on inexpensive antenna element arrays.
