ESE ES-410 GPS Based Frequency Generator

The ES-410 is a GPS-based frequency generator that locks a disciplined temperature-compensated crystal oscillator to GPS satellites, delivering a house 10 MHz reference that stations and networks can build their whole facility timing around. It won a 2016 NAB Best of Show Award from Radio Magazine for doing that job in a compact, ruggedized desktop enclosure rather than a full rack-mount frame.

Eight 10 MHz outputs split evenly between sine wave and 5-volt-logic square wave, so it can feed both analog and digital equipment simultaneously without external buffering, and a phase-coherent 1 PPS output keeps everything aligned to the UTC seconds transition. An indoor/outdoor GPS antenna with a 13-foot cable ships in the box, and the disciplined oscillator holds a 1x10⁻⁸ accuracy reference even through brief GPS signal interruptions.
