the clock frequency: the clock stability depends on the lamplight stability, setting a limit to GNSS performance. This problem is well known [2] but, for the first time, we have been able to analyze years of data from actual in-orbit RAFS to study the effect, uncovering the impact of the lamp on the clocks' performances and providing a

Combined with a Rubidium clock do I think you could get the best from both worlds. Long term and short term stability, but I might be wrong. ... This also shows that a 10x increase in jitter will increase its impact (raises the jitter-induced noise floor) by 20dB. So a first-order approximation is: 10ns jitter -> (105-20*log ...

with one clock approaching 11 years of continuous operation. The GPS Block IIF satellites will follow [4]. Boeing is the prime USAF contractor for the IIF Program. The Block IIF GPS satellites are expected to use a mix of rubidium and cesium standards. The current plan is to fly two (2) PerkinElmer rubidium standards and one (1) cesium standard.

In this block diagram, you can see a 10 MHz signal from the rubidium clock entering the time engine. This clock signal can be replaced by a 10 MHz SMA input. The clock signal feeds into a digital clock module and a digital PLL (12.5x resulted from 25 up and divided by 2), resulting in a 125 MHz frequency.

We present the results of 10 years of research related to the development of a Rubidium vapor cell clock based on the principle of pulsed optical pumping (POP). Since in the pulsed approach, the clock operation phases take place at different times, this technique demonstrated to be very effective in curing several issues affecting traditional …
