| JAN_SCI_RASTER | Observations of multiple frames in (m x n) positions targeted with a raster pointing of the S/C. The raster is done with a stop-and-go approach: the S/C maintain an inertial pointing allowing images acquisitions, then perform a slew to the new position and repeat the cycle till the (m x n) raster is completed. To be used while in J orbit or during FBs (out from CA phase).

| 3GM_JUPITER_OCCULTATION | The radio science experiment 3GM, with its 1-way 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. | 3GM |
|---|
| 3GM_IO_PLASMA_TORUS_OCCULTATION | The radio science experiment 3GM will use navigation data in X/X and X/Ka band to characterize the Io plasma torus. The data generated by the DST in 2-way dual-frequency radio links will be the primary observable to perform this investigation. 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 will stay MUTED and HAA in nominal SCIENCE.
Note that other observation strategy would be possible (2-way triple link, 1-way X and Ka link with USO UNMUTED). | 3GM |

| 3GM_GRAVITY_TOUR | Gravity measurement during flyby requires the use of the HGA.
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 CONFIGURATION mode at least 48 hours before the gravity measurement.
The observation should start with 1 hour of HAA in SELF_CALIBRATION mode. KaT starts with 10min of warm-up.
Additional X/X and X/Ka (DST) link may be required whenever the Sun-
Earth-Spacecraft angle is < 60 deg to cancel noise due to the solar wind plasma | 3GM |

| 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. USO is 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 SELF_CALIBRATION mode. KaT starts with 10min of warm-up. | 3GM |

| 3GM_BISTATIC_RADAR | Characterization of the surface by determination of roughness, dielectric constant of surface material and material density. The chosen antenna points towards surface, radio signal reflects from surface and received on ground. USO unmuted.
