3GM_RADIO_OCCULTATIONSThe radio science experiment 3GM, with its dual-frequency radio links (X and Ka-band) referenced to an ultrastable oscillator (USO), is performed as JUICE spacecraft moves in and out of occultation. Occultations occur throughout the jovian tour, but their phasing is not always synchronized with the timing of dedicated Jupiter observations by the other orbiter experiments. For instance, there are no occultations by Jupiter during the equatorial phase in 2030 and only 2 during the inclined orbital phase in 2031. The mission phase with the greatest number of Jupiter occultations (26) is the transfer to the Ganymede mission phase in 2032. The current planning tour offers a fairly regular sampling of latitudes between 54° S and 17° N and a rather global longitudinal coverage. USO unmuted, HAA in NOMINAL SCIENCE.
