3GM_USO_ONUSO is SWON and muted3GM
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. Note that 2 other options exist for torus occultations but are not (yet) defined in the database3GM

MAJIS_STANDBYAfter switch-on of MAJIS, the Boot SW automatically starts, and performs the primary boot from the PROM (Init fugitive BSW mode). After processor modules initialization, the Boot software goes to STANDBY mode. By default, the ASW Image0 (stored in MRAM0 = ASM0) is autonomously loaded after a timeout of 30 seconds. MAJIS then enters into ASW init Mode and then into SAFE mode. In STANDBY Mode, all channels are off, and only DPU HK SID1 are received. MAJIS needs to be maintained in STANDBY mode using the TC(17,1) in the following cases : - upload (using service 6) of new ASW images (or CUSW, or firmware) into MRAM: FCP-MAJ-070 describes the maintenance process. - upload a new BROWSE Table FCP-MAJ-060 into MRAM - select ASW Image1 and then start ASW Image 1 instead of teh default ASW Image0. FCP-MAJ-062 - any other update of MRAM using service 6MAJIS

MAJIS_JUP_STELLAR_OCCMAJIS will acquire several “subcubes” (number depends upon planet's speed over the sky) around the (fixed) star position, at different angular distances between the star and the planet's limb during the ingress/egress. Each sub-cube spans over several lines (around 6, less if S/C capability allows it) to compensate for possible pointing inaccuracies. Bright far moons can be used instead of stars as sources to decrease the repetition integration (and therefore spatial sampling) as the orbital velocity ranges from ~ 5 km/s at apojove to ~ 13 km/s at perijove satellite orientation: LIMB TANGENT (preferred, otherwise VERTICAL), to minimize straylight duration: About 10min 66 sec (max) for each subcube.

MAJIS_ICUTo monitor the radiometric performances of MAJIS using VISNIR and IR sources Specifically, there are several goals A) tracking the evolution of the actual levels (before subtracting for CDS) in the digital dynamics (0-65535 at 100 kHz, 0-4095 at 1 MHz). Such an evolution could lead to adjust an offset which can be selected by TC (4 settings) so as to avoid reaching digital saturation for the read image before analog saturation.
