JMAG_BURST_FIB_FOBBurst observation mode without scalar sensor JMAG
JMAG_DL_FIB_FOBThis observation is introduced to characterize JMAG operations during downlink times where power resources from the SC may be more limited, and where SC attitude is driven by operational constraints Only MAGOBS is operating.JMAG
JMAG_CONTINOP_FIB_FOBJ-MAG will measure the magnetic field in normal mode (at a rate of 32 vectors/s) continuously with SCA not operatingJMAG
JMAG_DLThis observation is introduced to characterize JMAG operations during downlink times where power resources from the SC may be more limited, and where SC attitude is driven by operational constraints. Only MAGOBS and MAGIBS are operating.JMAG
JMAG_CALROLLCampaign of spacecraft rolls to allow calibration of J-MAG magnetic field measurements. J-MAG will take data in gradiometer mode continuously while the spacecraft rolls about two principal axes, in regions where the Jovian magnetic field is >100 nT. Spacecraft rolls about two principal axes. 3 rolls of 360° about first axis at 0.5 rev/hr, then 3 rolls about the second axis (also at 0.5 rev/hr). The spacecraft rotation axes must always make an angle with the ambient magnetic field between 20° and 160°. JMAG
JMAG_BURSTOperation of J-MAG in burst mode (measurement at rate of 128 vectors/s) starting 10 minutes before and ending 10 minutes after a predicted crossing of a thin current sheet in Ganymedes magnetosphere (magnetopause/magnetotail current sheet).JMAG
JMAG_CONTINOPmeasure the magnetic field in normal mode (at a rate of 32 vectors/s) continuouslyJMAG
