History

Mnemonic:

DRAFT_3GM_GRAVITY_FLYBYS

Name:

DRAFT_3GM_GRAVITY_FLYBYS

Description:

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

Payload:

3GM

Pointing

Pointing Type:

Target:

PTRSnippet file:

Advanced

Scheduling Rules:

USO should be ON and scheduled in the background (TO BE SCHEDULED BY SOC AT PLANNING SET-UP)
HAA should be in STANDBY mode and scheduled in the background (TO BE SCHEDULED BY SOC AT PLANNING SET-UP).
If HAA is OFF, HAA needs to be ON at least 48hours before measurement starts.
3GM_GRAVITY should be scheduled for 3 consecutive communication passes centered around flyby C/A. If not PRIME, MGA is used.

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

Avoidance Rules:

no WOL should occur between 2 consecutive measurements

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