摘要：

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