Full film:3min10s. 1280×720,24fps; English on-screen explanation and optional closed captions; no audio.

## 00:00:00.000–00:00:04.000

Retain the inventory
Twelve 3U envelopes. Two independent six-cell banks.

## 00:00:04.000–00:00:10.000

Retrieve the captive pallet
The lift grips the reusable pallet before carrier locks release.

## 00:00:10.000–00:00:16.000

Index to the selected cell
The pallet rises to the source-cell loading plane.

## 00:00:16.000–00:00:25.000

Feed one CubeSat
Storage keepers open. Guided lead-screw pusher advances 250 mm.

## 00:00:25.000–00:00:30.000

Secure the transfer
Lift keepers retain the payload. Pusher retracts; cell gates close.

## 00:00:30.000–00:00:38.000

Lower to the launch plane
Loaded lift moves from 830 mm to the 46 mm launch datum.

## 00:00:38.000–00:00:43.000

Transfer custody to the sled
Carrier locks engage before the lift releases its pallet grips.

## 00:00:43.000–00:00:49.000

Clear. Prove. Arm.
Lift clear. Pallet locked. Source and arrest path ready.

## 00:00:49.000–00:00:54.000

Accelerate the loaded sled
1.300 m powered stroke. Evaluated commands: 1, 2 and 3 m/s.

## 00:00:54.000–00:00:58.000

Release the CubeSat
The payload departs; the pallet remains attached to the sled.

## 00:00:58.000–00:01:05.000

Arrest and return the carrier
210 mm arrest allocation. Retained carrier and pallet return.

## 00:01:05.000–00:01:10.000

Index the next retained cell
Eleven payloads remain. Repeat the controlled sequence.

## 00:01:10.000–00:01:20.000

Passive canisters release stored spring energy; VOLLEY commands a powered stroke.
Both start from the host-established orbital state.

## 00:01:20.000–00:01:30.000

Host trims or an ideal preset spring can match preplanned targets.
Actual deployer mechanisms and separation settings vary.

## 00:01:30.000–00:01:35.000

A generic restart-capable upper stage supplies the coarse move from 500 km circular.

## 00:01:35.000–00:01:40.000

A +27.42 m/s tangential burn enters the transfer ellipse.

## 00:01:40.000–00:01:45.000

Coast for 47.82 minutes in the same orbital plane.

## 00:01:45.000–00:01:50.000

A second +27.32 m/s burn circularizes the host at 600 km.

## 00:01:50.000–00:01:55.000

At delivery, VOLLEY sets the relative release vector; the host supplies maneuver authority.

## 00:01:55.000–00:02:00.000

Current ACR1 computations evaluate command points 1, 2 and 3 m/s.

## 00:02:00.000–00:02:05.000

The 3 m/s command gives a modeled payload inertial kick of 2.92694 m/s.

## 00:02:05.000–00:02:10.000

Retained sled motion and host recoil are included. The local schematic is not to scale.

## 00:02:10.000–00:02:15.000

Compare the same 600 km host state with a representative 1 m/s passive spring.

## 00:02:15.000–00:02:20.000

The 1 m/s P-POD-style example is a comparison choice, not a universal product rating.

## 00:02:20.000–00:02:25.000

An ideal ground-preset spring can match the same kick and the same ideal trajectory.

## 00:02:25.000–00:02:30.000

The 24-hour co-rotating zoom has separately scaled axes. It is not navigation accuracy.

## 00:02:30.000–00:02:35.000

The 3 m/s command example creates a 600 by 610.82 km ellipse.

## 00:02:35.000–00:02:40.000

Perigee remains at 600 km. The orbital period is about 96.80 minutes.

## 00:02:40.000–00:02:45.000

A circle at apogee requires another propulsion event: about +2.926 m/s here.

## 00:02:45.000–00:02:50.000

Coast follows the ellipse. Circularization requires a separate burn.

## 00:02:50.000–00:02:54.000

0.2 m/s is an illustration outside the current evaluated command points.

## 00:02:54.000–00:02:58.000

Current modeled points are 1, 2 and 3 m/s. This view shows the 3 m/s command.

## 00:02:58.000–00:03:02.000

About 16 m/s is a historical periodic-model result, not a current ACR1 rating.

## 00:03:02.000–00:03:06.000

1 km/s is future kinematic research, shown separately from the current rail.

## 00:03:06.000–00:03:10.000

3.5 km/s gives an unbound path: a future kinematic case, not current rail capability.
