History

Mnemonic:

MAJ_SAT_FLYBY_MEDRES

Name:

MAJ Satellite Medium Resolution

Description:

Flyby observations of the satellite surface with vertical (N-S) slews or MAJIS scan providing medium spatial resolution (e.g.resolution from 3 km to 1 km/pixel for Ganymede). Perform when the S/C moves slowly from approach YS phase to PB phase and during PB phase
Duration: a few minutes maximum

Payload:

MAJIS

Pointing

Pointing Type:

nadir

Target:

PTRSnippet file:

Advanced

Scheduling Rules:

+/-1H around C/A (equivalent to +/-20000 km range for Ganymede, +/-13000 km range for Europa, +/-7000 km for Callisto range) but excluding phase near C/A during which MAJ_SAT_FLYBY_HR is required

any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc

Avoidance Rules:

near C/A during which MAJIS_Flyby_HR is required

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