We used cesium standards to manage the timing on our LORAN C transmitter timers in the USCG. At the time, they had their own rack and the room they were in was the most temp controlled on base. Now it's board mounted...wow.

Yeah, that is a fantastic bit of technology. I too have worked with Rubidium and cesium clock standards. Tony Parkes

The performance of this unit from the spec's given is really quite impressive especially if it can keep those spec's over temperature and vibration. I worked with a GPS timing receiver in the late '80s. We used a $40K cesium clock to monitor the performance of our system. The clock was very sensitive to temperature changes and power cycles. In a benign environment the long term stability of that $40K unit was about 5 x 10-11. In the early '90s, a rubidium clock was about 3 x 4 x 4 and cost $4K with similar performance in benign environments. These guys have built a pretty impressive device. You need to have worked in the field to really appreciate what they have.

It looks little costly but it is wonderful product for military and aerospace industry. If they desing and give it in various form factor (to replace old obsolete devices), it will be very good for lagacy sustainment program in miliitary.

Maybe the next generation will use MEMs technology to create a wristwatch sized unit...
