What is a rubidium frequency standard?

Rubidium Atomic Frequency Standard. The RAFS (Rubidium Atomic Frequency Standard) is a space-qualified radiation hard high-performance 10.00 MHz frequency standard based on the atomic refer- ence given by the spectral absorption line of the Rb87 isotope.

How accurate is a rubidium clock?

A rubidium clock will be used as a second, technologically independent time source. It is accurate to within 1.8 nanoseconds over 12 hours.

How does a rubidium oscillator work?

How does a rubidium oscillator work? In simple terms, the physics package contains a chamber of rubidium gas, a light is shone through the gas and the level of this light is detected. The rubidium gas is excited by microwave energy at the transition frequency of the gas.

What is GPS frequency standard?

All GPS satellites broadcast on at least two carrier frequencies: L1, at 1575.42 MHz, and L2, at 1227.6 MHz (newer satellites also broadcast on L5 at 1176 MHz).
