3GM Radio Occultations
The 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.
Note that 2 other options exist for torus occultations but are not (yet) defined in the database

Latitudes should be repeated at regular intervals to characterise evolution of wave phenomena and middle-atmospheric temperatures. Occultation observations are event-driven and defined by the Earth-SC line reaching the '1-bar level plus 1000 km'
any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc

conditions that make the observation not possible (e.g. thruster firing)
