Abstract
We present the first results of the engineering model of the cold atom space clock PHARA.O. A relative frequency stability of 4.2 times 10-13t-1/2 with a quartz oscillator and of 2.5 times 10-13t-1/2 with a cryogenic oscillator have been obtained on the ground with a single path in a Ramsey cavity designed for micro gravity operation.
