The Rubidium Atomic Frequency Standard (RAFS) from Orolia is a state-of-the-art ultra-stable atomic clock able to deliver a frequency stability of 2x10-14 over averaging intervals of 10’000 s. It is designed with the latest technologies, providing advanced features, such as long lifetime, high reliability, lightweight and ultra-low phase noise, for next-generation space applications. The RAFS unit is composed of two main parts, the clock itself named “RAFS core” and the Electronic Power Conditioning name “EPC” which includes the DC/DC converter and the electrical interface to the satellite. The EPC design can be adapted to the satellite’s need.

The RAFS delivers an output frequency of 10 MHz with a phase noise of -120 dBc at a 10 Hz offset and has harmonics of less than -40 dBc. It is available in a chassis that measures 217 x 124 x 117 mm and is suitable for use in navigation satellites, space scientific missions, military communication satellites, tracking and guidance control, and advanced low orbit digital communication satellite. The device requires a DC supply voltage of 28 V and has an operating power of up to 35 W.
