  The paper describes the results achieved in the development of the compact
transportable fully automated optical clock based on a single 171Yb+ ion in a
radiofrequency (RF) quadrupole trap. The resulted measurements demonstrated the
4.9E-16 output RF signal relative instability on 1000 s integration time with
298.1 kg weight, 0.921 volume, and 2.766 kW input power consumption of the
device. A transformation of the ultrastable optical signal into the RF range
was performed via the optical frequency comb with a supercontinuum fiber laser
generator. The transformation was conducted without loss of initial stability
and accuracy characteristics of the signal.
