EON SPACE VENTURES · SIMULATION PROCEDUREFolded solar array deployment and return with a clearance hold
ESV-S01-SOP-02 · Payload satellite · model v5 · 12 steps
Rehearse a controlled array deployment and return using both folded-array groups. Detect a harness obstruction before movement, recover to a clear route and restore the stowed configuration with its retention evidence.
Concept-model training and authoring specification. Real hardware operations require the programme owner’s approved procedure and engineering limits.
Before the exercise
Use an inert spacecraft model with the payload protected and fixture secured. The author supplies array membership, reference axes, stowed and demonstration-deployed poses, keep-out envelopes and a clearance-fault variant. These kinematic poses do not establish a real deployment mechanism.
1 Confirm the spacecraft and fixture
Model labels: bus, base, solar_r, solar_l
Select the bus, fixture and both folded arrays. Save the accepted stowed pose and identify which array is scheduled to move first.
Check: A reversed left/right selection or mismatched model revision blocks the sequence.
2 Establish the movement boundary
Model labels: objective, optics, foot_rf, foot_lf
Mark the optical aperture as a no-contact zone and confirm the fixture support state. Identify the complete array sweep envelope supplied by the scenario.
Check: The learner must acknowledge the protected payload and movement envelope before releasing retention.
3 Trace the hinge and retention groups
Model labels: solar_r, solar_r_center_strap, hinge_rft, hinge_rfb
Select the right array, its centre strap and the displayed hinge references. Confirm the authored array group includes its leaf, strips and hinge attachments.
Check: Reject movement of a single solar-cell surface while its supporting group remains fixed.
4 Find the obstructing harness
Model labels: cable_r, cable_r_sleeve, cable_r_head_clip, solar_r
Present the right harness crossing the planned movement envelope. Compare that route with the approved clearance snapshot and place the work on hold.
Check: Continuing the deployment through the displayed obstruction is a critical error.
5 Recover the harness route
Model labels: cable_r, cable_r_sleeve, cable_r_head_clip
Return the array to its safe starting pose if needed. Route the harness to the scenario-defined clear position, restore the sleeve and engage the retaining clip.
Check: The hold is resolved only after the saved route and retention states agree.
6 Release the right retention state
Model labels: solar_r_center_strap, solar_r, solar_r_inner_leaf
Support the right array in the simulated fixture and release the authored retention state. Select the whole right array group for controlled movement.
Check: Support must precede release. The virtual strap state is separate from any unmodelled release hardware.
7 Deploy the right array
Model labels: solar_r, solar_r_inner_leaf, hinge_rft, hinge_rrt
Move the right array along the reviewed kinematic path to the stored demonstration pose. Pause at the intermediate clearance checkpoint and capture the pose.
Check: A wrong axis, disconnected leaf or crossed keep-out envelope prevents progression.
8 Deploy the left array
Model labels: solar_l, solar_l_inner_leaf, solar_l_center_strap, hinge_lft
Repeat support, retention release and staged movement for the left group. Compare the resulting left/right configuration with the approved scene snapshot.
Check: Do not apply the right-side path blindly to the mirrored left assembly.
9 Check the deployed work configuration
Model labels: solar_r, solar_l, cable_l, cable_r, objective
Review both array poses, the optical no-contact zone and the visible harness routes. Submit the prescribed geometric clearance evidence before returning to stow.
Check: Only the declared geometric checks are assessed; electrical output is not inferred from the solar-cell texture.
10 Return the arrays in the reviewed order
Model labels: solar_l, solar_r, hinge_lft, hinge_rft
Return the left array and then the right array along their reverse authored paths, stopping at the same intermediate checkpoints.
Check: Preserve the specified order and prevent a shortcut through the protected payload envelope.
11 Restore retention and covers
Model labels: solar_l_center_strap, solar_r_center_strap, bus_top_hatch, bus_front_top_hatch
Restore the stowed retention states, confirm both bus access covers are in their baseline positions and inspect the saved harness-clearance view.
Check: Missing retention or an access cover in the movement envelope prevents completion.
12 Record the return to baseline
Model labels: solar_l, solar_r, cable_r_head_clip, base
Compare final group transforms with the stowed baseline and hand over the obstruction, recovery, deployment and return records.
Check: Completion requires accepted final poses, resolved hold and complete retention evidence.
Assessment and completion
Score group identification 20, preparation and support 20, clearance recovery 25, movement order and final poses 25, and handover 10. Passing through an obstruction or releasing an unsupported array prevents completion.
Authoring and headless handoff
Create explicit group bindings for each array and its leaves. Use authored kinematic poses with a stated demonstration axis and clearance envelope. Do not derive an actual flight joint, release system or energy model from appearance. Record every hold, pose checkpoint and retention-state transition.
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.
