An Ultra Stable Oscillator is being developed by AccuBeat (named USO) for the Gravity and Geophysics of Jupiter and the Galilean Moons (3GM) radio occultation experiment of the ESA JUICE mission. This paper reviews the oscillator design and the critical issues to be tackled. The USO is a compact 15×13×10cm3 oscillator, based on a quartz crystal resonator and highly stable double oven. A Partial Engineering Model of (PEM) was built and tested in thermal vacuum. The PEM with 5MHz output has…
