EON SPACE VENTURES · SIMULATION PROCEDUREOptical head access and protective hood restoration
ESV-S06-SOP-01 · Earth observation satellite · model v3 · 12 steps
Practise accessing the optical head without disturbing its lens, harness or nearby service interfaces. Resolve a cover-selection error and restore the assembly to its protected baseline.
Concept-model training and authoring specification. Real hardware operations require the programme owner’s approved procedure and engineering limits.
Before the exercise
Use the unpowered Earth-observation satellite on its support frame. Supply a no-contact zone for the optical surface, an authored hood parking pose and the access-cover sequence. Real cleanliness classes, alignment limits and handling methods require the programme procedure.
1 Identify the instrument and support
Model labels: support, bus, optics
Select the support frame, spacecraft bus and optical head, then save the baseline pose and model revision.
Check: The optical task must not move the independent support assembly.
2 Set the protected work state
Model labels: optics.lens, optics.rim, optics.hood
Mark the lens as a no-contact surface and establish the scenario isolation and controlled-access state.
Check: The learner acknowledges the protected surface before any cover movement.
3 Trace the instrument harness
Model labels: optics.harness, harness.left, harness.right
Identify the optical harness and distinguish it from the bus side routes. Save the authored route used by this exercise.
Check: Selecting a bus harness as the instrument connection is rejected.
4 Resolve the cover mismatch
Model labels: hatch, optics.hood, optics.band
Present an instruction pointing to the bus hatch rather than the optical hood. Place a hold and identify the intended cover.
Check: Opening the unrelated hatch after the mismatch is a critical error.
5 Prepare the hood removal path
Model labels: optics.hood, optics.rim, optics.harness
Preview the authored hood translation and its clearance from the rim and harness. Confirm the parked location.
Check: The path must remain outside the configured optical no-contact zone.
6 Remove and park the hood
Model labels: optics.hood, optics.band, optics
Release the exercise retention state and move the hood into its parked pose while keeping the optical head fixed.
Check: Record the correct hood identity, path and parked state.
7 Expose the access context
Model labels: optics.liner, optics.lens, optics.patch
Identify the liner, lens and patch surfaces now accessible. Compare them with the supplied reference condition card.
Check: A condition decision must cite the card or observed geometry, not invented internals.
8 Restore the optical harness route
Model labels: optics.harness, harness.rear.left, junction.rear
Use the scenario route reference to correct a displaced optical harness segment without changing the rear bus junction.
Check: The target route is restored and the protected junction remains unchanged.
9 Prepare the hood for refit
Model labels: optics.hood, optics.rim, optics.band
Return the hood from its parked pose to the authored alignment point and compare orientation with the baseline.
Check: A reversed or incomplete alignment prevents the seating action.
10 Seat and retain the hood
Model labels: optics.hood, optics.band, optics.rim
Move the hood into its saved seated pose and restore the simulation retention state. Keep the lens untouched.
Check: Assess seated pose and retention state against declared authoring criteria.
11 Verify the surrounding configuration
Model labels: optics.harness, connectors.left, connectors.right, hatch
Confirm that the optical route, side connectors and unrelated hatch remain in the intended final states.
Check: The comparison must identify both the corrected route and unchanged interfaces.
12 Hand over the protected instrument
Model labels: optics, optics.hood, optics.lens, support
Submit the cover-selection recovery, final pose comparison and evidence of the protected optical surface.
Check: Complete only when access is closed and no unresolved protection hold remains.
Assessment and completion
Score object identification 20, optical protection 25, cover-discrepancy recovery 20, route and pose restoration 20 and evidence 15. Contact with the protected lens, moving the wrong hatch or unsupported retention assumptions triggers a stop.
Authoring and headless handoff
Author the hood as a declared detachable cover unless a verified mechanism is supplied. Use separate condition cards and protected envelopes. This exercise does not demonstrate optical performance, cleanliness certification or alignment accuracy; those require independent records.
Reuse the exact GLB and part identifiers. Verify the supported Genesis import and binding path before generation. These are procedure specifications; they do not claim a completed Genesis run.
