Abstract :
This paper describes the achieved results of a new space Rubidium Atomic Frequency Standard (named Robust-RAFS) through the description of the internal coefficients influence reduction and the positive consequences in term of clock frequency stability and predictability improvements. Performances achievements during uninterrupted operation of several months demonstrate a monotonic behavior, a stability of 1×10-14 @105 sec. and a drift per day of few 10-14.
