| 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. USO unmuted, HAA in NOMINAL SCIENCE.
Note that 2 other options exist for torus occultations but are not (yet) defined in the database | 3GM |

| DRAFT_3GM_OCCULTATION | 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. USO unmuted, HAA in NOMINAL SCIENCE.

| DRAFT_3GM_GRAVITY_TOUR | KaT and HAA should be operating during gravity measurement
USO assumed to be ON during the full tour: this should be defined in the scenario set-up and not at 3GM observation approach.
HAA should be in STANDBY mode at least 48 hours before the gravity measurement.
The observation should start with 1 hour of HAA in CALIBRATION mode. KaT starts with 10min of warm-up. | 3GM |

| DRAFT_3GM_GRAVITY_GCO500_200 | Gravity measurement during GCO500 and GCO200 will use the HGA during downlink sessions. If not possible, it will use the MGA. KaT and HAA should be operating during gravity measurement. USOis OFF during this phase (except in case of BSR opportunity). HAA should be in STANDBY mode at least 48 hours before the gravity measurement. The observation should start with 1 hour of HAA in CALIBRATION mode. KaT starts with 10min of warm-up. | 3GM |

| DRAFT_3GM_GRAVITY_FLYBYS | Gravity measurement during flyby requires the use of the MGA.
